Addressing puerperal hematomas postpartum presents considerable challenges for obstetric care providers. While hematomas such as those affecting the vulva, vulvovaginal region, or paravaginal area are frequently encountered, retroperitoneal hematomas are rare and notably pose a greater risk to the life of the patient. The medical literature contains scant case reports on retroperitoneal hematomas, with no consensus on a definitive treatment approach. Pelvic arterial embolization has emerged as both a sensible and increasingly preferred method for treating these hematomas recently, but its application is contingent upon the patient maintaining hemodynamic stability and the availability of a specialized interventional embolization unit. In our case, we are presenting a very rare case of a 31-year-old primigravida female with a history of in vitro fertilization pregnancy. She delivered a normal vaginal delivery at 31 weeks gestation. Unfortunately, she experienced multiple complications intrapartum, including preeclampsia and placental abruption. These complications increased her risk of developing a broad ligament hematoma.展开更多

This case report reflects on this condition. A 45-year-old female, a known case of adenomyosis, presented with intermittent fever and foul vaginal discharge. These symptoms occurred shortly after the patient underwent UAE for menorrhagia secondary to adenomyosis. Computed tomography scan of the abdomen and pelvis aided in the diagnosis of Pyomyoma secondary to UAE. After a trial of broad spectrum antibiotics and Suction and Evacuation of the uterus had little to no help in the patient’s condition, she underwent Total Abdominal Hysterectomy in which a big, organized pus collection was removed from the uterus. Conclusion: Pyomyoma should be considered in the differentials for patients presenting with fever and vaginal discharge post UAE.展开更多

Hydromorphone(10 mg) was dispensed into a 100 ml PCA pump with normal saline. Pump administration was initiated 15 min before the start of the procedure, and the intraoperative dose was adjusted according to patient pain level. A numerical rating scale was used to evaluate pain immediately after embolization, 5 min after embolization, at the end of the procedure, and 6, 12, 24, 48, and 72 h after the procedure. Side effects were also observed.Results: Thirty-three patients underwent uterine artery embolization via the right radial artery. Patient pain was well controlled at all time points surveyed, and patients reported satisfaction with analgesia. The median length of hospital stay was 5 days. There were 7 cases of adverse reactions, but no serious side effects were observed.Conclusion: Patients reported positive experiences with arterial embolization of uterine fibroids via the right radial artery. Hydromorphone PCA effectively controlled pain. The PCA pump is easy to operate, has a low incidence of adverse reactions, and offers economic benefits at the patient and institutional levels.展开更多

We hypothesize that the formation of postoperative adhesions can impose technical difficulties for UAE, resulting in longer fluoroscopy time and less reduction of uterus and largest tumor volumes after the procedure. Methods: We retrospectively reviewed the medical records of 122 consecutive patients who underwent uterine artery embolization for the treatment of uterine fibroids in our department. Patients were divided into two groups according to the presence or absence of previous abdominal or pelvic surgery. Fluoroscopy time, change in symptoms, and volume variation of uterus and largest tumor were compared between groups. Results: Forty-seven patients underwent abdominopelvic surgery before UAE (Group 1) and 75 did not (Group 2). Median (IQR) fluoroscopy time was 22 minutes (IQR: 18 - 26.4) for Group 1, and 23.3 minutes (IQR: 19.05 - 28.25) for Group 2. No difference was found between the groups (P = 0.17). Regarding the results after UAE, neither the change in symptoms (P = 0.30) nor the volume variation for uterus (P = 0.41) and largest fibroid (P = 0.18) showed significant difference. Conclusions: In this study, previous abdominopelvic surgeries had no significant influence on fluoroscopy time, and overall outcomes of uterine artery embolization.展开更多

Nevertheless, the potential impact on endometrial morphological and functional outcomes after the procedure is still controversial based on reports of endometritis or eventual transient ischemia. This study evaluated endometrial reorganization in uterine leiomyoma patients, before and after AEM, through gene expression analyses of extracellular matrix and cytokines genes in theendometrial tissue. Eight patients with leiomyomas were evaluated before AEM and 6 months after. The examinations included transvaginal pelvic ultrasonography, dosing of the follicle-stimulating hormone, and endometrial biopsy during the second phase of the menstrual cycle. RNA was extracted from endometrial samples, cDNA was synthesized, and applied on PCR arrayTM plates to evaluate the expression of extracellular matrix (ECM) genes and cytokines and their receptors’ genes (CYT). The ECM overexpressed genes were MMP (1, 3, 10, 11, and 14), CTGF1, ICAM1, TBHS1, ITGA2, ITGA3, ITGB3, COL7A1, COL12A, SPP1, and TNC;ADAMTS8 was underexpressed. The CYT overexpressed genes were SPP1, BCL6, CXCL12, IL-8, and CEBPB;CXCL13 and CCL21 were underexpressed. The ECM results showed overexpression of proteases that are responsible for dysfunctions in the ECM, and of genes responsible for adhesion and membrane components. The CYT results showed overexpression of chemokines responsible for endometrial repair, and underexpression of cytokines involved in inflammatory processes in the endometrial tissue. AEM treatment did not negatively affect the endometrial function at 6 months after embolization. This study broadens the knowledge about using a procedure that is relevant to the treatment of leiomyomas and contributes to the establishment of future guidelines for the decision making process for physicians and patients.展开更多

文摘BACKGROUND Hemorrhoidal artery embolization(Emborrhoid)is a novel method for the treatment of severe hemorrhoidal bleeding.Despite having a technical success rate of 93%-100%,the clinical success ranges between 63%and 94%,with a rebleeding rate of 13.6%.AIM To evaluate the effectiveness of this procedure in reducing hemorrhoidal flow and hemorrhoidal bleeding.METHODS This prospective observational pilot study was conducted at Division of General Surgery 1 and Tertiary Referral Pelvic Floor Center,Treviso Regional Hospital,Italy.In a 2 months period(February-March 2022),consecutive patients with hemorrhoidal bleeding scores(HBSs)≥4,Goligher scores of II or III,failure of non-operative management,and a candidate for Emborrhoid were included.Endoanal ultrasound with eco-Doppler was performed preoperatively and 1 month after the procedure.The primary endpoint was to quantify the changes in arterial hemorrhoidal flow after treatment.The secondary endpoint was to evaluate the correlation between the flow changes and the HBS.RESULTS Eleven patients underwent Emborrhoid.The overall pretreatment mean systolic peak(MSP)was 14.66 cm/s.The highest MSP values were found in the anterior left lateral(17.82 cm/s at 1 o’clock and 15.88 cm/s at 3 o’clock)and in the posterior right lateral(14.62 cm/s at 7 o’clock and 16.71 cm/s at 9 o’clock)quadrants of the anal canal.After treatment,the overall MSP values were significantly reduced(P=0.008)although the correlation between MSP and HBS changes was weak(P=0.570).A statistical difference was found between distal embolization compared with proximal embolization(P=0.047).However,the coil landing zone was not related to symptoms improvement(P=1.000).A significant difference in MSP changes was also reported between patients with type 1 and type 2 superior rectal artery(SRA)anatomy(P=0.040).No relationship between hemorrhoidal grades(P=1.000),SRA anatomy(P=1.000)and treatment outcomes was found.CONCLUSION The preliminary findings of this pilot study confirm that Emborrhoid was effective in reducing the arterial hemorrhoidal flow in hemorrhoidal disease.However,the correlation between the post-operative MSP and HBS changes was weak.Hemorrhoidal grade,SRA anatomy and type of embolization were not related to treatment outcomes.

文摘Uterine fibroids are benign tumors that originate from smooth muscle cells of the uterus.It is the most common gynecological disorder,affecting up to 80%of women of reproductive age.Uterine fibroids can cause various symptoms such as abnormal uterine bleeding,pelvic pain,infertility,and pregnancy complications.The treatment options for uterine fibroids include medical therapy,surgical intervention,and minimally invasive techniques.AIM To compare ovarian function of women with uterine fibroids who did or did not undergo uterine artery embolization(UAE).METHODS This prospective cohort study enrolled 87 women with symptomatic uterine fibroids who underwent UAE,and 87 women with the same symptoms who did not undergo UAE but received conservative management or other treatments.The two groups were matched for age,body mass index,parity,and baseline characteristics of uterine fibroids.The primary outcome was ovarian function that was evaluated by serum levels of follicle-stimulating hormone(FSH),luteinizing hormone(LH),estradiol(E2),and anti-Müllerian hormone(AMH),as well as ovarian reserve tests,such as antral follicle count(AFC)and ovarian volume(OV).The secondary outcome was fertility that was evaluated based on the menstrual cycle,ovulation,conception,pregnancy,and delivery.The participants were followed-up for 36 months and assessed at 1,3,6,12,24,and 36 months after treatment.RESULTS The study found that the most common minor complication of UAE was postembolization syndrome in 73.6% of women,resolving within a week.No significant differences were observed between the UAE group and the control group in serum levels of reproductive hormones(FSH,LH,E2,AMH)and ovarian reserve indicators(AFC,OV)at any point up to 36 months post-treatment.Additionally,there were no significant differences in conception,pregnancy,or delivery rates,with the average time to conception and gestational age at delivery being similar between the two groups.Birth weights were also comparable.Finally,there was no significant correlation between ovarian function,fertility indicators,and the type or amount of embolic agent used or the change in fibroids posttreatment.CONCLUSION UAE resulted in significantly positive pregnancy outcomes,no adverse events post-treatment,and is a safe and effective treatment for uterine fibroids that preserves ovarian function and fertility.
文摘BACKGROUND Splenic rupture associated with Behçet’s syndrome(BS)is extremely rare,and there is no consensus on its management.In this case report,a patient with BSassociated splenic rupture was successfully treated with splenic artery embolization(SAE)and had a good prognosis after the intervention.CASE SUMMARY The patient was admitted for pain in the left upper abdominal quadrant.He was diagnosed with splenic rupture.Multiple oral and genital aphthous ulcers were observed,and acne scars were found on his back.He had a 2-year history of BS diagnosis,with symptoms of oral and genital ulcers.At that time,he was treated with oral corticosteroids for 1 month,but the symptoms did not alleviate.He underwent SAE to treat the rupture.On the first day after SAE,the patient reported a complete resolution of abdominal pain and was discharged 5 d later.Three months after the intervention,a computed tomography examination showed that the splenic hematoma had formed a stable cystic effusion,suggesting a good prognosis.CONCLUSION SAE might be a good choice for BS-associated splenic rupture based on good surgical practice and material selection.
文摘Broad ligament hematoma is typically seen during cesarean section due to rupture of branches of uterine and vaginal vessels and it’s rare to be seen post-normal vaginal delivery. Addressing puerperal hematomas postpartum presents considerable challenges for obstetric care providers. While hematomas such as those affecting the vulva, vulvovaginal region, or paravaginal area are frequently encountered, retroperitoneal hematomas are rare and notably pose a greater risk to the life of the patient. The medical literature contains scant case reports on retroperitoneal hematomas, with no consensus on a definitive treatment approach. Pelvic arterial embolization has emerged as both a sensible and increasingly preferred method for treating these hematomas recently, but its application is contingent upon the patient maintaining hemodynamic stability and the availability of a specialized interventional embolization unit. In our case, we are presenting a very rare case of a 31-year-old primigravida female with a history of in vitro fertilization pregnancy. She delivered a normal vaginal delivery at 31 weeks gestation. Unfortunately, she experienced multiple complications intrapartum, including preeclampsia and placental abruption. These complications increased her risk of developing a broad ligament hematoma.
文摘Pyomoyoma is a rare complication of Uterine Artery Embolization (UAE). This case report reflects on this condition. A 45-year-old female, a known case of adenomyosis, presented with intermittent fever and foul vaginal discharge. These symptoms occurred shortly after the patient underwent UAE for menorrhagia secondary to adenomyosis. Computed tomography scan of the abdomen and pelvis aided in the diagnosis of Pyomyoma secondary to UAE. After a trial of broad spectrum antibiotics and Suction and Evacuation of the uterus had little to no help in the patient’s condition, she underwent Total Abdominal Hysterectomy in which a big, organized pus collection was removed from the uterus. Conclusion: Pyomyoma should be considered in the differentials for patients presenting with fever and vaginal discharge post UAE.
文摘Objective: To evaluate the efficacy and safety of patient-controlled analgesia(PCA) with hydromorphone as perioperative analgesia during uterine artery embolization(UAE) via the right radial artery.Patients and methods: A total of 33 patients with uterine fibroids, who underwent UAE at the authors’ hospital between June 2021 and March 2022, were selected. Hydromorphone(10 mg) was dispensed into a 100 ml PCA pump with normal saline. Pump administration was initiated 15 min before the start of the procedure, and the intraoperative dose was adjusted according to patient pain level. A numerical rating scale was used to evaluate pain immediately after embolization, 5 min after embolization, at the end of the procedure, and 6, 12, 24, 48, and 72 h after the procedure. Side effects were also observed.Results: Thirty-three patients underwent uterine artery embolization via the right radial artery. Patient pain was well controlled at all time points surveyed, and patients reported satisfaction with analgesia. The median length of hospital stay was 5 days. There were 7 cases of adverse reactions, but no serious side effects were observed.Conclusion: Patients reported positive experiences with arterial embolization of uterine fibroids via the right radial artery. Hydromorphone PCA effectively controlled pain. The PCA pump is easy to operate, has a low incidence of adverse reactions, and offers economic benefits at the patient and institutional levels.
文摘Objective: To assess the influence of previous abdominal and pelvic surgeries on uterine artery embolization (UAE). We hypothesize that the formation of postoperative adhesions can impose technical difficulties for UAE, resulting in longer fluoroscopy time and less reduction of uterus and largest tumor volumes after the procedure. Methods: We retrospectively reviewed the medical records of 122 consecutive patients who underwent uterine artery embolization for the treatment of uterine fibroids in our department. Patients were divided into two groups according to the presence or absence of previous abdominal or pelvic surgery. Fluoroscopy time, change in symptoms, and volume variation of uterus and largest tumor were compared between groups. Results: Forty-seven patients underwent abdominopelvic surgery before UAE (Group 1) and 75 did not (Group 2). Median (IQR) fluoroscopy time was 22 minutes (IQR: 18 - 26.4) for Group 1, and 23.3 minutes (IQR: 19.05 - 28.25) for Group 2. No difference was found between the groups (P = 0.17). Regarding the results after UAE, neither the change in symptoms (P = 0.30) nor the volume variation for uterus (P = 0.41) and largest fibroid (P = 0.18) showed significant difference. Conclusions: In this study, previous abdominopelvic surgeries had no significant influence on fluoroscopy time, and overall outcomes of uterine artery embolization.
文摘BACKGROUND Bibliometric analysis can be used to assess the current state of the literature and publication trends on a given topic.There has not been a review of this kind on prostatic artery embolization(PAE)for benign prostatic hyperplasia(BPH).PAE is a relatively new and somewhat controversial treatment option for BPH.Given the novelty and controversy,there has been much research published on the topic recently.AIM To survey the current state of research on PAE for BPH by using bibliometric analysis to analyze the top 50 most highly cited articles.METHODS A cross-sectional study was performed using the Web of Science database to identify the most cited articles published on PAE for BPH as of June 2022.Articles that did not primarily focus on PAE or BPH as an indication were eliminated.The 50 most cited articles were carried forward for analysis.RESULTS All but 6 articles were published in the last decade with contributions from 15 countries.Fifty-two percent of the studies had a C level of evidence.The majority were published in the Journal of Vascular and Interventional Radiology and Cardiovascular and Interventional Radiology.Twenty percent(n=10)of the articles were published in urologic journals.On average,articles published in urologic journals tended to be more recent.The mean year of publication for an article in a urological journal was 2016.6 compared to 2013.9 in a non-urologic journal(P=0.02).Seventy percent of the articles focused on clinical outcomes,while only 2%focused on practice guidelines.Self-citations accounted for 11.4 citations perarticle on average,corresponding to 14.7%of all citations analyzed.CONCLUSION The most influential papers on this topic represent a fairly recent body of work with contributions from a wide variety of countries and journals.The fact that articles in urologic journals were published significantly more recently than articles on the list in non-urologic journals may suggest that the field of urology is starting to accept PAE for a wider range of indications.Finally,while there has been much high-quality research published,more influential studies on practice guidelines and technique may be beneficial.

文摘BACKGROUND Vaginal myomectomy is the most common form of radical treatment for prolapsed submucosal leiomyoma and is typically performed under general anesthesia.However,an alternative treatment approach is needed for patients who cannot tolerate general anesthesia.We describe a case with such a patient who was successfully treated via a minimally invasive method under local anesthesia.CASE SUMMARY A 46-year-old female suffered from abnormal uterine bleeding,severe anemia,and a reduced quality of life attributed to a massive prolapsed submucosal leiomyoma.She could not tolerate general anesthesia due to a congenital thoracic malformation and cardiopulmonary insufficiency.A new individualized combined treatment,consisting uterine artery embolization(UAE),percutaneous microwave ablation(PMWA)of the pedicle and the endometrium,and transvaginal removal of the leiomyoma by twisting,was performed.The lesion was completely removed successfully under local anesthesia without any major complications.The postoperative follow-up showed complete symptom relief and a significant improvement in the quality of life.CONCLUSION UAE combined with PMWA can be performed under local anesthesia and is a promising alternative treatment for patients who cannot tolerate general anesthesia.
文摘Prostate artery embolization is a well-known and promising treatment for benign prostatic hyperplasia, with the quantum leaps of research in medicine. We aim to provide an up-to-date review of the novel technique, including large retrospective studies and randomized control trials, ends with discussions of advantages and disadvantages of this minimally invasive technique.
文摘BACKGROUND Prostate artery embolization(PAE)is a promising minimally invasive therapy that improves lower urinary tract symptoms(LUTS)related to benign prostatic hyperplasia(BPH).Transurethral resection of the prostate(TURP)is the gold standard therapy for LUTS/BPH.AIM To evaluate the efficacy and safety of PAE vs TURP on LUTS related to BPH.METHODS A literature review was performed to identify all published articles on PAE vs TURP for LUTS/BPH.Sources included PubMed,Embase,Cochrane library databases,and Chinese databases before June 2022.A systematic review and meta-analysis were conducted.Outcome measurements were combined by calculating the mean difference with a 95%confidence interval.Statistical analysis was carried out using Review Manager 5.3.RESULTS Eleven studies involving 1070 participants were included.Compared with the TURP group,the PAE group had a similar effect on the International Index of Erectile Function(IPSS)score,Peak urinary flow rate(Qmax),postvoid residual volume(PVR),Prostate volume(PV),prostatic specific antigen(PSA),The International Index of Erectile Function short form(IIEF-5)scores,and erectile dysfunction during 24 mo follow-up.Lower quality of life(QoL)score,lower rate of retrograde ejaculation and shorter hospital stay in the PAE group.There was no participant death in either group.A higher proportion of haematuria,urinary incontinence and urinary stricture was identified in the TURP group.CONCLUSION PAE may be an appropriate option for elderly patients,patients who are not candidates for surgery,and patients who do not want to risk the potential adverse effects of TURP.Studies with large cases and long follow-up time are needed to validate results.
文摘BACKGROUND Duplicate renal malformation is a congenital disease of the urinary system,with an incidence rate of 0.8%.Surgical treatment is suitable for symptomatic patients.Urinary fistula is one of the complications of heminephrectomy.Long-term urinary fistula has a great impact on patients'lives.CASE SUMMARY This article mainly reports on a 47-year-old man with duplication of kidney deformity,long urinary fistula after partial nephrectomy,and no improvement after conservative treatment.We have achieved positive results in the arterial embolization treatment of the residual renal artery,indicating that selective arterial embolization is a good way to treat urinary fistula after partial nephrectomy.It is worth noting that this patient violated the Weigert-Meyer law,which also gave us more consideration.CONCLUSION Renal artery embolization may be a simple and safe method to treat urinary fistula inefficacy with conservative treatment.
文摘Objective:To investigate the association between magnetic resonance imaging(MRI)classification and symptom relief after uterine artery embolization(UAE)in patients with adenomyosis.Methods:Totally,73 patients with symptomatic adenomyosis who underwent UAE were retrospectively analyzed.Preoperative MRI classification was defined as:type Ⅰ,high signal on both T2-weighted images(T2WI)and T1-weighted images(T1WI);type Ⅱ,high signal only on T2WI,and type Ⅲ,high signal on neither T1WI nor T2WI.Dysmenorrhea was measured with the visual-analog scales and the degree of menorrhagia was measured according to the number of sanitary pads used in one menstrual cycle.Dysmenorrhea and menorrhagia were measured before UAE and 12 months after UAE.Results:The number of the type Ⅰ,Ⅱ,Ⅲ cases was 23,37,and 13,respectively.The baseline characteristics of the three groups exhibited no significant difference.The alleviation rates of dysmenorrhea among type Ⅰ,Ⅱ,Ⅲ cases were 73.9%,89.2%,and 84.6%,respectively(P=0.455).The alleviation rates of menorrhagia for type Ⅰ,Ⅱ,Ⅲ were 69.6%,78.4%,and 92.3%,respectively(P=0.714).Conclusion:Pre-procedure MRI classification and symptom relief after UAE exhibited no significant association.UAE has a favorable mid-term control on dysmenorrhea and menorrhagia among patients with adenomyosis.Preoperative MRI classification might not indicate symptom relief.More research is needed before changing clinical practice.
文摘BACKGROUND Contrast-induced nephropathy(CIN)is a reversible form of acute kidney injury that occurs within 48-72 h of exposure to intravascular contrast material.CIN is the third leading cause of hospital-acquired acute kidney injury and accounts for 12%of such cases.Risk factors for CIN development can be divided into patientand procedure-related.The former includes pre-existing chronic renal insufficiency and diabetes mellitus.The latter includes high contrast volume and repeated exposure over 72 h.The incidence of CIN is relatively low(up to 5%)in patients with intact renal function.However,in patients with known chronic renal insufficiency,the incidence can reach up to 27%.AIM To examine the association between renal enhancement pattern on non-contrast enhanced computed tomographic(CT)images obtained immediately following hepatic artery embolization with development of CIN.METHODS Retrospective review of all patients who underwent hepatic artery embolization between 01/2010 and 01/2011(n=162)was performed.Patients without intraprocedural CT imaging(n=51),combined embolization/ablation(n=6)and those with chronic kidney disease(n=21)were excluded.The study group comprised of 84 patients with 106 procedures.CIN was defined as 25%increase above baseline serum creatinine or absolute increase≥0.5 mg/dL within 72 h post-embolization.Post-embolization CT was reviewed for renal enhancement patterns and presence of renal artery calcifications.The association between noncontrast CT findings and CIN development was examined by Fisher’s Exact Test.RESULTS CIN occurred in 11/106(10.3%)procedures(Group A,n=10).The renal enhancement pattern in patients who did not experience CIN(Group B,n=74 with 95/106 procedures)was late excretory in 93/95(98%)and early excretory(EE)in 2/95(2%).However,in Group A,there was a significantly higher rate of EE pattern(6/11,55%)compared to late excretory pattern(5/11)(P<0.001).A significantly higher percentage of patients that developed CIN had renal artery calcifications(6/11 vs 20/95,55%vs 21%,P=0.02).CONCLUSION A hyperdense renal parenchyma relative to surrounding skeletal muscle(EE pattern)and presence of renal artery calcifications on immediate post-HAE noncontrast CT images in patients with low risk for CIN are independently associated with CIN development.

文摘Prostatic artery embolization(PAE)has gained acceptance as a minimally invasive,safe and effective treatment of symptomatic benign prostatic hyperplasia.Radiologic imaging is an indispensable part of post-interventional evaluation of PAE and serves both clinical and investigational purposes.In this context,ultrasonography(US)has a central and multifaceted role.Gray-scale US is routinely utilized for measurement of significant outcome parameters(prostatic volume,intra-vesical prostatic protrusion and post-void residual volume)before and after PAE.Improvement of these parameters may become more obvious onemonth post-PAE,or later.Contrast-enhanced US(CEUS)with intravenous administration of a second-generation echo-enhancer can demonstrate prostatic infarcts(as enhancement defects)immediately post-PAE and monitor their resolution over time.The volume of prostatic infarcts can also be measured and compared to prostatic volume.Prostatic infarction is a definite sign of the local efficacy of PAE and a predictor of prostate shrinkage and(at least in some patients)of clinical success.CEUS can also be performed intraoperatively in the angio-suite,for on-site evaluation of the ischemic effect;a variation of this technique,with intraarterial(instead of intravenous)administration of diluted echo enhancer,can also be applied intraoperatively,to map the embolized territory and to prevent non-target embolization.Initial experience with USelastographic techniques(shear-wave and strain elastography)has shown that they can detect and quantify the improvement of tissue elasticity post-PAE,thus providing new insights into the therapeutic mechanisms of this treatment.With utilization of high-end equipment,experience and standardized imaging protocols,US could be the primary modality for imaging evaluation of PAE.

文摘Arterial embolization of myomas (AEM) is an established option for the conservative treatment of uterine leio-myomas;it treats all present uterine nodules at once, is less invasive than other procedures and effective in controlling symptoms, and does not require long term hospitalizations. Nevertheless, the potential impact on endometrial morphological and functional outcomes after the procedure is still controversial based on reports of endometritis or eventual transient ischemia. This study evaluated endometrial reorganization in uterine leiomyoma patients, before and after AEM, through gene expression analyses of extracellular matrix and cytokines genes in theendometrial tissue. Eight patients with leiomyomas were evaluated before AEM and 6 months after. The examinations included transvaginal pelvic ultrasonography, dosing of the follicle-stimulating hormone, and endometrial biopsy during the second phase of the menstrual cycle. RNA was extracted from endometrial samples, cDNA was synthesized, and applied on PCR arrayTM plates to evaluate the expression of extracellular matrix (ECM) genes and cytokines and their receptors’ genes (CYT). The ECM overexpressed genes were MMP (1, 3, 10, 11, and 14), CTGF1, ICAM1, TBHS1, ITGA2, ITGA3, ITGB3, COL7A1, COL12A, SPP1, and TNC;ADAMTS8 was underexpressed. The CYT overexpressed genes were SPP1, BCL6, CXCL12, IL-8, and CEBPB;CXCL13 and CCL21 were underexpressed. The ECM results showed overexpression of proteases that are responsible for dysfunctions in the ECM, and of genes responsible for adhesion and membrane components. The CYT results showed overexpression of chemokines responsible for endometrial repair, and underexpression of cytokines involved in inflammatory processes in the endometrial tissue. AEM treatment did not negatively affect the endometrial function at 6 months after embolization. This study broadens the knowledge about using a procedure that is relevant to the treatment of leiomyomas and contributes to the establishment of future guidelines for the decision making process for physicians and patients.

文摘BACKGROUND High flow priapism(HFP)is a rare type of priapism.Perineal trauma is the most common cause of HFP.Trauma-induced penile artery injury may lead to an arterial-cavernosal fistula,whereas persistent irregular arterial blood flow entering the corpora cavernosum can cause a persistent penile erection.The routine treatment of HFP focuses on addressing the abnormal penile erectile status and avoiding post-treatment erectile dysfunction.Interventional embolization is an important therapeutic modality for HFP,and bilateral embolization therapy is currently the most commonly used technique for patients with bilateral cavernous artery fistulas;however,unilateral embolization therapy has yet to be reported.CASE SUMMARY Herein,we report of the case of a 26-year-old Chinese male who presented with a persistent abnormal erection for 12 h after perineal impact injury.Medical history,cavernous arterial blood gas analysis and radiological examinations led to a diagnosis of HFP caused by bilateral cavernous artery fistulas.We performed routine conservative treatment(compression therapy and ice application)for the patient after admission;however,10 d later,his symptoms had not been relieved.After completion of the preoperative workup,right(severe side)selective perineal artery embolization was performed;the left cavernous artery fistula was left untreated.After postoperative continuation of conservative treatment for 72 h,the patient experienced complete penile thinning.The patient had no symptoms of erectile dysfunction over a follow-up period of 12 mo.CONCLUSION Compared with bilateral cavernous artery fistula embolization,we believe that unilateral cavernous artery fistula embolization can achieve positive clinical efficacy and reduce the risk of postoperative erectile dysfunction secondary to penile ischemia.

文摘BACKGROUND Hepatocellular carcinoma(HCC)is a prevalent malignancy,and transcatheter arterial embolization(TAE)has emerged as a pivotal therapeutic modality.How-ever,TAE may induce symptom distress and fatigue,adversely affecting the quality of life of patients.AIM To investigate symptom distress,fatigue,and associated factors in HCC patients undergoing TAE.METHODS We used a cross-sectional design and purposive sampling to enroll HCC patients who underwent TAE at our institution from January to December 2022.Question-naires were utilized to collect data on symptom distress and fatigue scores from the first to the third day after TAE.RESULTS Our study revealed a significant reduction in fatigue and symptom distress among patients after TAE.Pain,fatigue,insomnia,fever and abdominal dis-tension were the most common symptoms troubling patients during the first 3 d post-TAE.Marital status,presence of family support,physical functional status,age,and symptom distress were identified as predictors of fatigue in patients.CONCLUSION Healthcare professionals should educate HCC patients on symptom distress and INTRODUCTION Hepatocellular carcinoma(HCC)ranks as the fifth most prevalent cancer and the third leading cause of cancer-related mortality globally.Surgical intervention remains the cornerstone of HCC treatment;however,due to the challenges associated with early diagnosis and the lack of specific diagnostic markers,a considerable proportion of patients are diagnosed at advanced stages,rendering them ineligible for surgical interventions.Transcatheter arterial embolization(TAE)is an interventional therapeutic approach involving the insertion of a fine catheter via the femoral artery to reach the vasculature near the tumor site.TAE aims to obstruct the arterial supply to the tumor by deploying embolic agents,thereby inducing necrosis in cancer cells.This procedure is suitable for patients with good liver function and overall health,particularly those with large HCCs that have not invaded the portal vein[1,2].Nonetheless,following TAE,hepatocytes incur variable degrees of damage,leading to the development of a constel-lation of symptoms reminiscent of acute hepatitis.These symptoms include fatigue and systemic discomfort,such as nausea,vomiting,fever,abdominal pain,as well as transient elevations in aspartate aminotransferase(AST)and alanine aminotransferase(ALT),collectively referred to as postembolization syndrome[3,4].These symptoms may arise due to ischemia of the liver and gallbladder,temporary liver enlargement,and peritoneal irritation.While many studies have explored fatigue and symptom distress in cancer patients both nationally and internationally,with some focusing on symptom distress following transcatheter arterial chemoembolization,there has been limited in-depth investigation into the fatigue and symptom distress resulting from TAE treatment[5-8].Fatigue and pain are both subjective experiences,typically arising from the gradual depletion of energy reserves during the course of illness[9].Fatigue is particularly prevalent among cancer patients,with rates soaring as high as 90%.Despite extensive research exploring cancer-related fatigue and its influencing factors,a unanimous consensus remains elusive.Hence,the primary objective of this study was to investigate the symptom distress and fatigue experienced by liver cancer patients following TAE treatment and to analyze potential contributing factors.
文摘This paper reports a case of a 38-year-old young man with a lower extremity arterial thrombus diagnosed by ultrasound, which was traced back to the left ventricular thrombus. By reviewing the relevant literature, the relationship between lower extremity arterial thrombosis and left ventricular thrombosis is described, and which examination method is the most valuable in the diagnosis of thrombosis is discussed.
文摘Background:Hemoptysis is a significant clinical entity with high morbidity and potential mortality.Both medical management (in terms of resuscitation and bronchoscopic interventions) and surgery have severe limitations in these patients population.Bronchial artery embolization (BAE) represents the first-line treatment for hemoptysis.This article discusses clinical analysis,embolization approach,outcomes and complications of BAE for the treatment of hemoptysis.Methods:A retrospective analysis of 344 cases,who underwent bronchial arteriography at Tianjin Haihe Hospital between 2006 and 2013.Several aspects of outcome were analyzed:Demographics,clinical presentation,radiographic studies,results,complications and follow-up of BAE.Results:Three hundred and forty-four consecutive patients underwent bronchial arteriography,336 of 344 patients (97.7%) performed BAE; there were 1530 coils for 920 arteries embolized; the main responsible sources for bleeding were right bronchial artery (29.7%),left bronchial artery (21.6%),combined right and left bronchial trunk (18.4%),right intercostal arteries (13.3%); 61 patients (17.7%) had recurrent hemoptysis within 1 month after undergoing BAE,74 patients (21.5%) had recurrent hemoptysis over 1 month after undergoing BAE; The common complications of BAE included subintimal dissection,arterial perforation by a guide wire,fever,chest pain,dyspnea,etc.The follow-up was completed in 248 patients,28 patients had been dead,21 patients still bleed,92 patients had lost to follow-up.Conclusions:The technique of BAE is a relatively safe and effective method for controlling hemoptysis.The complications of BAE are rare.Although the long-term outcome in some patients is not good,BAE may be the only life-saving treatment option in patients who are poor surgical candidates.
