Transanal eco-Doppler evaluation after hemorrhoidal artery embolization

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.

Impact of uterine artery embolization on ovarian function and pregnancy outcome after uterine-fibroids treatment:A prospective study

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.

Pyomyoma as a Complication of Uterine Artery Embolization (A Case Report)

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.

Spontaneous Paravesical and Broad Ligament Hematoma after Vaginal Delivery Had Uterine Artery Embolization after Evacuating the Hematoma

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.

Successful splenic artery embolization in a patient with Behçet’s syndrome-associated splenic rupture:A case report

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.

Efficacy of patient-controlled hydromorphone analgesia in those undergoing uterine fibroid artery embolization via the right radial artery

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.

High-flow priapism due to bilateral cavernous artery fistulas treated by unilateral embolization:A case report

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.

Transcatheter embolization for hemorrhage from aberrant testicular artery after partial nephrectomy:A case report

BACKGROUND Arterial bleeding typically involves the renal artery following partial nephrectomy;in this study,we present a case of bleeding originating from the testicular artery that has not been reported in previous studies.CASE SUMMARY A 52-year-old man suffered hemorrhage from a perinephric branch of the aberrant left testicular artery after an open nephron-sparing surgery for renal cell carcinoma.Clinical signs of bleeding were manifested by the patient,such as fresh blood drainage from the catheter,decreased hemoglobin levels,and significant vital sign changes.Since computed tomography did not show evidence of active bleeding,transcatheter angiography was conducted to identify the bleeding site.Fluoroscopic spot images confirmed bleeding derived from a perinephric branch of the testicular artery originating from the segmental artery of the left renal artery.Using n-butyl-2-cyanoacrylate,successful transcatheter arterial embolization of the affected branch was performed.Immediately after the embolization procedure,the bleeding ceased,and the patient experienced complete recovery devoid of complications.CONCLUSION In patients with postoperative arterial hemorrhage after partial nephrectomy,the testicular artery can be a rare but notable source of bleeding.Accurate bleeding site localization via angiographic evaluation,followed by transcatheter arterial embolization,can be instrumental for safe,prompt,and effective hemostasis.

Influence of Previous Abdominal and Pelvic Surgeries on Uterine Artery Embolization

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.

Top 50 most cited articles on prostatic artery embolization for benign prostatic hyperplasia:A bibliometric review

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.

Influence of transcatheter arterial embolization on symptom distress and fatigue in liver cancer patients

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.

Safety and efficacy of transcatheter arterial embolization in autosomal dominant polycystic kidney patients with gross hematuria: Six case reports

BACKGROUND To retrospectively report the safety and efficacy of renal transcatheter arterial embolization for treating autosomal dominant polycystic kidney disease(ADPKD)patients with gross hematuria.CASE SUMMARY The purpose of this study is to retrospectively report the safety and efficacy of renal transcatheter arterial embolization for treating ADPKD patients with gross hematuria.Materials and methods:During the period from January 2018 to December 2019,renal transcatheter arterial embolization was carried out on 6 patients with polycystic kidneys and gross hematuria.Renal arteriography was performed first,and then we determined the location of the hemorrhage and performed embolization under digital subtraction angiography monitoring.Improvements in routine blood test results,routine urine test results,urine color and postoperative reactions were observed and analyzed.Results:Renal transcatheter arterial embolization was successfully conducted in 6 patients.The indices of 5 patients and the color of gross hematuria improved after surgery compared with before surgery.No severe complication reactions occurred.CONCLUSION For autosomal dominant polycystic kidney syndrome patients with gross hematuria,transcatheter arterial embolization was safe and effective.

Perforating and ophthalmic artery variants from the anterior cerebral artery:Two case reports

BACKGROUND The diagnosis and therapy during surgery depend largely on a full account of anatomic characteristics.Apart from regular structures,the common,less common or even uncommon anatomic variations are critical for procedural planning.This is especially true during craniocerebral microsurgery,where small vascular variations can affect the final surgical results and patient prognosis.CASE SUMMARY Herein,two rare variations concerning the A1(horizontal)segment of anterior cerebral artery(ACA1)were introduced.One enabled the communication between perforating branch of ACA1 and dural artery of anterior skull base,which was discovered during autopsy.The other was ophthalmic artery(OA)originating from ACA1,shown on digital angiography.CONCLUSION In this study,we found two rare anatomical variations.One was an abnormal OA originated from the anterior communicating artery.The other was a perforating branch of the A1 segment of the anterior cerebral artery,which communicated with meningeal vessels in the anterior skull base.This finding is of great significance for the treatment of anterior communicating artery aneurysm or in other anterior skull base surgery.

Uterine artery embolization combined with percutaneous microwave ablation for the treatment of prolapsed uterine submucosal leiomyoma:A case report

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.

Ultrasound Traced the Embolization of Lower Extremity Artery to Left Ventricular Thrombus: A Case Report

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.

Renal artery embolization in the treatment of urinary fistula after renal duplication:A case report and review of literature

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.

Arterial Embolization: A Superior Treatment for Massive Urinary Tract Bleeding in Emergency Care

Objective:To analyze the effect of arterial embolism(AE)in patients with massive urinary system bleeding(MBUS).Methods:From September 2018 to September 2023,175 cases of MBUS patients in the emergency department of the hospital were randomly selected and divided into groups according to the length of stay.Among them,85 cases(September 2018–September 2020)underwent bladder irrigation treatment with aluminum potassium sulfate solution through a catheter(Group A),and 90 cases(October 2020–September 2023)underwent AE treatment(Group B).The treatment effects of the two groups were compared.Results:The treatment effectiveness of Group B is higher than that of Group A(P<0.05).The urinary hemoglobin level of Group B is lower than that of Group A at 1,6,12,and 24 hours after treatment(P<0.05).Among the 90 cases treated with AE,7 cases had a fever,with body temperatures ranging from 37.3°C to 38.9℃,with a mean temperature of 38.2±0.3℃.Four cases experienced local pain,nausea,and vomiting,while two cases of intra-iliac AE showed transient buttock pain.These patients with adverse reactions were treated symptomatically for 7 days.All patients recovered after treatment.Intravenous urography of 87 patients in June showed that the renal pelvis and calyces were in good condition,the renal function returned to normal,and the blood urea nitrogen and blood creatinine test results were within the normal range.After 1 year of follow-up,no hypertension occurred.Conclusion:AE treats MBUS patients in the emergency department with remarkable efficacy.It has the advantages of less damage to the body,rapid hemostasis,high safety,and maximum preservation of organ function.

Efficacy and safety analysis of transarterial chemoembolization and transarterial radioembolization in advanced hepatocellular carcinoma descending hepatectomy

BACKGROUND Hepatocellular carcinoma(HCC)is one of the most common malignant tumors in the world,which is seriously threatening the lives of patients.Due to the rapid development of the disease,patients were in the middle and advanced stages at the time of diagnosis and missed the best time for treatment.With the development of minimally invasive medicine,interventional therapy for advanced HCC has achieved promising results.Transarterial chemoembolization(TACE)and transarterial radioembolization(TARE)are currently recognized as effective treatments.This study aimed to investigate the clinical value and safety of TACE alone and combined with TACE in the treatment of progression in patients with advanced HCC and to find a breakthrough for the early diagnosis and treatment of patients with advanced HCC.AIM To investigate the efficacy and safety of hepatic TACE and TARE in advanced descending hepatectomy.METHODS In this study,218 patients with advanced HCC who were treated in the Zhejiang Provincial People’s Hospital from May 2016 to May 2021 were collected.Of the patients,119 served as the control group and received hepatic TACE,99 served as the observation group and were treated with hepatic TACE combined with TARE.The patients in two groups were compared in terms of lesion inactivation,tumor nodule size,lipiodol deposition,serum alpha-fetoprotein(AFP)level in different periods,postoperative complications,1-year survival rate,and clinical symptoms such as liver pain,fatigue,and abdominal distension,and adverse reactions such as nausea and vomiting.RESULTS The observation group and the control group had good efficacy in treatment efficiency,reduction of tumor nodules,reduction of postoperative AFP value,reduction of postoperative complications,and relief of clinical symptoms.In addition,compared with the control group,the treatment efficiency,reduction of tumor nodules,reduction of AFP value,reduction of postoperative complications,and relief of clinical symptoms in the observation group were better than those in the TACE group alone.Patients in the TACE+TARE group had a higher 1-year survival rate after surgery,lipiodol deposition was significantly increased and the extent of tumor necrosis was expanded.The overall incidence of adverse reactions in the TACE+TARE group was lower than that in the TACE group,and the difference had statistical significance(P<0.05).CONCLUSION Compared with TACE alone,TACE combined with TARE is more effective in the treatment of patients with advanced HCC.It also improves postoperative survival rate,reduces adverse effects,and has a better safety profile.

Uterine Artery Embolization for Management of Primary Postpartum Hemorrhage Associated with Placenta Accreta

Objective To evaluate the efficacy and safety of uterine artery embolization(UAE) in the management of primary postpartum hemorrhage associated with placenta accreta. Methods We retrospectively reviewed the medical records of patients with placenta accreta between January 2010 and August 2014. Totally 18 women(mean age 30.8±4.2 years) of primary massive postpartum hemorrhage with diagnosis of placenta accrete received treatment of UAE after delivery. Images of DSA and medical records were reviewed. Technical success was defined as control of bleeding after embolization. The complications, control of hemorrhage and recurrent bleeding of the placenta left inside the uterus were retrospectively collected for assessment. Results All patients underwent transcatheter embolization of bilateral uterine arteries. The technical success rate of embolization was 100%. Bleeding was controlled in 17 of 18 patients(94%) during follow-up period(median 18 months, 3-31months) without further bleeding recurred. One patient with placenta percreta undertook an emergent hysterectomy along with surgical bladder repair after UAE because of persistent uterine bleeding. Eight patients had postembolization syndrome and no other complications occurred. Conclusion Uterine artery embolization is an effective and safe treatment for the management of primary postpartum massive hemorrhage associated with placenta accreta.

Total splenic artery embolization for splenic artery aneurysms in patients with normal spleen

AIM: To evaluate total embolization of the main splenic artery in patients with splenic artery aneurysms (SAAs) and normal spleen.
