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

Seco...AIM To study tumor response, and tolerability of arterially directed embolic therapy(ADET) with polyethylene glycol embolics loaded with irinotecan for the treatment of colorectal cancer liver metastases(CRC-LM). Secondary objectives were to monitor quality of life, time to progression and survival of patients.METHODS Patients were included in the study if they were affected by CRC-LM, refractory to systemic chemotherapy, treated with ADET using polyethylene glycol embolics, and had liver involvement < 50%. Tumor response, performance status(PS), tumor marker antigens, and quality of life(QoL) were monitored at 1, 3 and 6 mo after ADET. QoL was assessed with the Palliative Performance Scale(PPS).RESULTS We treated 50 consecutive CRC-LM patients with ADET using polyethylene glycol embolics. Their tumor response one month after ADET was: 28% of complete response(CR), 48% of partial response(PR), 8% stable disease(SD), and 16% of progression. Tumor response 3 mo after ADET was CR 24%, PR 38%, SD 19% and progression disease(PD) 19%. Tumor response 6 mo after ADET was CR 18%, PR 44%, SD 21% and PD 18%. QoL was 90% PPS at each time point. Median time to progression for patients who progressed was 2.5 mo(range 0.8-6). Median follow-up was 14 mo(0.8-25 range). ADETs were performed with no complications. Observed side effects(mild or moderate intensity) were: Pain in 32% of patients, increase of transaminase levels in 20% and fever in 14%, whereas 30% of patients did not complain any adverse event. CONCLUSION The treatment of unresectable CRC-LM with ADET using polyethylene glycol microspheres loaded with irinotecan was effective in tumor response and resulted in mild toxicity, and good QoL.展开更多

文摘BACKGROUND Left cardiac myxoma(CM)is the most common benign tumor of primary cardiac tumors,but because of its special position caused by pathological physiology change,caused by the complications of the heavier,the surface is often accompanied by blood clots,once fall out,it causes peripheral vascular embolization,such as acute lower limb artery embo-lization,harmfulness is large,high morbidity,and easy to occur repeatedly.CASE SUMMARY A 67-year-old male patient suddenly appeared numbness and weakness of the left lower limb and could not walk without obvious incentive.The patient was finally diagnosed as left CM complicated with acute lower limb arterial embolism after completing cardiac ultrasound,computer tomography angiography,and histopathological analysis,such as hematoxylin-eosin stain staining,immunohistochemistry and special staining including alcian blue staining and periodic acid schiff staining.Arterial thrombosis was removed successfully by femoral artery thrombectomy,postoperative numbness and weakness of the patient’s left lower limb disappeared,skin temperature became warm,and dorsal foot artery pulsation was accessible.The patient was readmitted to the hospital 8 mo after discharge for left atrial mass resection,and was diagnosed as CM by postoperative histopathological examination.CONCLUSION Although CM is rare,it may be considered as the source of embolism in patients with acute limb ischemia.Repeated loss of thrombus on the tumor and its surface may lead to repeated embolism of peripheral vessels.Cardiac ultrasound is helpful for early diagnosis.Here,we use this case report to highlight left CM as an important cause of acute limb ischemia and to report our experience in the diagnosis and treatment of lower limb arterial embolism caused by CM detachment.
文摘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.

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BACKGROUND Through significant advances in the treatment of peripheral arterial occlusive disease,acute ischemia of the lower extremity is still associated with significant morbidity,limb threat and mortality.The two main causes of acute ischemia in lower extremities are arterial embolism and atherosclerotic arteries.Timely recognition and treatment of acute limb ischemia in emergency situations is essential in order to minimize the duration of ischemia.AIM To investigate the application effect of angiojet thrombolysis in the treatment of acute lower extremity arterial embolization.METHODS Sixty-two patients with acute lower extremity arterial embolization admitted to our hospital from May 2018 to May 2020 were selected.Among them,the observation group(twenty-eight cases)had received angiojet thrombolysis,and the control group(thirty-four cases)had received femoral artery incision and thrombectomy.After thrombus clearance,significant residual stenosis of the lumen was combined with balloon dilation and/or stent implantation.When the thrombus removal was not satisfactory,catheter-directed thrombolysis was performed.The incidence of postoperative complications,recurrence rate and recovery of the two groups were compared.RESULTS There were no significant differences in postoperative recurrence(target vessel reconstruction rate),anklebrachial index and the incidence of postoperative complications between the two groups(P>0.05);there were statistically significant differences in postoperative pain score and postoperative rehabilitation between the two groups(P<0.05).CONCLUSION The application of angiojet in the treatment of acute lower limb artery thromboembolism disease is safe and effective,minimally invasive,quicker recovery after operation,less postoperative complications,which is more suitable for the treatment of femoral popliteal arterial thromboembolism lesions.If the thrombus removal is not satisfactory,the combination of coronary artery aspiration catheter and catheterized directed thrombolysis can be used.Balloon dilation and stent implantation can be considered for obvious lumen stenosis.

文摘BACKGROUND Klebsiella pneumoniae(K.pneumoniae)is a clinically common Gram-negative bacillus that can cause community-and hospital-acquired infections and lead to pneumonia,liver abscesses,bloodstream infections,and other infectious diseases;however,severe pneumonia caused by hypervirulent K.pneumoniae(hv Kp)complicated by acute intra-abdominal multiple arterial thrombosis and bacterial embolism is rarely seen in the clinical setting and has not been reported in the literature.CASE SUMMARY A 51-year-old man was hospitalized with fever and dyspnea.Persistent mild pain in the middle and upper abdomen began at dawn on the 3rd day following admission and developed into persistent severe pain in the left upper abdomen 8h later.Based on chest computed tomography(CT),bronchoscopy,bronchoalveolar lavage fluid metagenomic next-generation sequencing,abdominal aortic CT angiography(CTA),and culture of the superior mesenteric artery embolus,adult community-acquired severe hv Kp pneumonia complicated by acute intraabdominal multiple arterial thrombosis and bacterial embolism was diagnosed.Notably,he recovered and was discharged from the hospital after receiving effective meropenem anti-infection,endovascular contact thrombolytic,and systemic anticoagulant therapies and undergoing percutaneous thrombus aspiration.Ten days later,the patient returned to the hospital for abdominal CTA examination,which indicated blocked initial common pathway of the celiac trunk and superior mesenteric artery,and local stenosis.Therefore,celiac trunk artery stenting was performed in Chongqing Hospital,and postoperative recovery was good.CONCLUSION We report a case of hv Kp severe pneumonia complicated by acute intra-abdominal multiple arterial thrombosis and bacterial embolism and suggest that clinicians should consider the possibility of a Gram-negative bacillus infection and conduct effective pathogen detection in a timely fashion when managing patients with severe community-acquired pneumonia before obtaining bacteriologic and drug sensitivity results.At the same time,when patients have severe pulmonary infection complicated by severe abdominal pain,an acute mesenteric artery embolism should be considered to avoid delays in treatment.
文摘BACKGROUND Transcatheter arterial embolization(TAE)has been widely used as an effective and a safe treatment method and was often used as an alternative to the surgical management,but there are limited studies on the efficacy and the safety for patients undergoing their secondary postpartum hemorrhage(PPH).AIM To evaluate the usefulness of TAE for secondary PPH focusing on the angiographic findings.METHODS We conducted a research from January 2008 to July 2022 on all 83 patients(mean:32 years,range:24-43 years)presented with secondary PPH and they were treated with TAE in two university hospitals.The medical records and angiography were retrospective reviewed in order to evaluate the patients’characteristics,delivery details,clinical status and peri-embolization management,angiography and embolization details,technical/clinical success and complications.The group with active bleeding sign and the group without it were also compared and analyzed.RESULTS On angiography,46(55.4%)patients showed active bleeding signs such as contrast extravasation(n=37)or pseudoaneurysm(n=8)or both(n=1),and 37(44.6%)patients showed non-active bleeding signs such as only spastic uterine artery(n=2)or hyperemia(n=35).In the active bleeding sign group there were more multiparous patients,low platelet count,prothrombin time prolongation,and high transfusion requirements.The technical success rates were 97.8%(45/46)in active bleeding sign group and 91.9%(34/37)in non-active bleeding sign group,and the overall clinical success rates were 95.7%(44/46)and 97.3%(36/37).An uterine rupture with peritonitis and abscess formation occurred to one patient after the embolization,therefore hysterostomy and retained placenta removal were performed which was a major complication.CONCLUSION TAE is an effective and a safe treatment method for controlling secondary PPH regardless of angiographic findings.
文摘BACKGROUND Various treatment methods are available for the treatment of pancreatic arteriovenous malformation(P-AVM);however,there are no established treatment options for asymptomatic P-AVM.CASE SUMMARY A 47-year-old and a 50-year-old male patients sought treatment for P-AVM in the pancreas,which was incidentally detected during routine abdominal computed tomography and magnetic resonance imaging conducted as part of a health check-up.They underwent transcatheter arterial embolization(TAE),and over the course of a 9-year follow-up period,the AVM did not worsen and was asymptomatic.CONCLUSION TAE can be considered as an alternative treatment option for P-AVM in selective cases where patients are asymptomatic or have a high surgical risk.

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BACKGROUND Gastrointestinal bleeding(GIB)is a severe and potentially life-threatening condition,especially in cases of delayed treatment.Computed tomography angiography(CTA)plays a pivotal role in the early identification of upper and lower GIB and in the prompt treatment of the haemorrhage.AIM To determine whether a volumetric estimation of the extravasated contrast at CTA in GIB may be a predictor of subsequent positive angiographic findings.METHODS In this retrospective single-centre study,35 patients(22 men;median age 69 years;range 16-92 years)admitted to our institution for active GIB detected at CTA and further submitted to catheter angiography between January 2018 and February 2022 were enrolled.Twenty-three(65.7%)patients underwent endoscopy before CTA.Bleeding volumetry was evaluated in both arterial and venous phases via a semi-automated dedicated software.Bleeding rate was obtained from volume change between the two phases and standardised for unit time.Patients were divided into two groups,according to the angiographic signs and their concordance with CTA.RESULTS Upper bleeding accounted for 42.9%and lower GIB for 57.1%.Mean haemoglobin value at the admission was 7.7 g/dL.A concordance between positive CTA and direct angiographic bleeding signs was found in 19(54.3%)cases.Despite no significant differences in terms of bleeding volume in the arterial phase(0.55 mL vs 0.33 mL,P=0.35),a statistically significant volume increase in the venous phase was identified in the group of patients with positive angiography(2.06 mL vs 0.9 mL,P=0.02).In the latter patient group,a significant increase in bleeding rate was also detected(2.18 mL/min vs 0.19 mL/min,P=0.02).CONCLUSION In GIB of any origin,extravasated contrast volumetric analysis at CTA could be a predictor of positive angiography and may help in avoiding further unnecessary procedures.
文摘A 44-year-old patient was admitted with tumor rupture in the left hepatic lateral lobe,and he underwent emergent exploratory laparotomy and proceeded for hepatic left lateral lobectomy on September 19,2021.The final diagnosis of hepatocellular carcinoma was confirmed by histopathological examination of the surgical specimen.Afterward,the patient received hepatic arterial infusion chemotherapy with FOLFOX(oxaliplatin,fluorouracil,and leucovorin)for 5 cycles.Subsequently,recurrence of the hepatocellular carcinoma was diagnosed in the abdominal cavity.The patient was then treated with lenvatinib.Within less than 1 month of the treatment with lenvatinib,the patient was admitted to the emergency room on June 2,2022,because of acute intra-abdominal bleeding(hematomas).Percutaneous intra-abdominal angiography found that the bleeding vessels were the right gastroepiploic artery and left gastric artery.The patient was stabilized after arterial embolization using gelatin sponges.The diagnosis and management of spontaneous intra-abdominal hematomas are discussed.
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The surgical removal of renal cancer,along with the thrombectomy of the inferior vena cava tumour thrombus,represents a remarkable milestone in urological surgery.This procedure is not only technically demanding but also requires a high level of surgical expertise.Managing renal cancer combined with a vena cava tumour thrombus poses significant challenges,especially when dealing with combined grade Ⅱ-Ⅳ inferior vena cava tumour thrombus.The complexity of these cases is further exacerbated by the delicate anatomical structures involved and the need to preserve critical vessels while effectively removing the tumour.The Upper Urethral Tumour Treatment Centre of Weifang People's Hospital successfully treated a challenging case of left renal tumour combined with grade II inferior vena cava tumour thrombus.The surgical team,led by experienced urological surgeons,meticulously planned and executed the procedure,ensuring minimal trauma to the patient and complete removal of the tumour.This achievement not only demonstrates the hospital's commitment to providing state-of-the-art surgical care but also highlights the importance of continued research and training in urological oncology.The successful outcome of this case is a testament to the expertise and dedication of the medical team and offers hope to patients facing similar complex surgical challenges.
文摘AIM To study tumor response, and tolerability of arterially directed embolic therapy(ADET) with polyethylene glycol embolics loaded with irinotecan for the treatment of colorectal cancer liver metastases(CRC-LM). Secondary objectives were to monitor quality of life, time to progression and survival of patients.METHODS Patients were included in the study if they were affected by CRC-LM, refractory to systemic chemotherapy, treated with ADET using polyethylene glycol embolics, and had liver involvement < 50%. Tumor response, performance status(PS), tumor marker antigens, and quality of life(QoL) were monitored at 1, 3 and 6 mo after ADET. QoL was assessed with the Palliative Performance Scale(PPS).RESULTS We treated 50 consecutive CRC-LM patients with ADET using polyethylene glycol embolics. Their tumor response one month after ADET was: 28% of complete response(CR), 48% of partial response(PR), 8% stable disease(SD), and 16% of progression. Tumor response 3 mo after ADET was CR 24%, PR 38%, SD 19% and progression disease(PD) 19%. Tumor response 6 mo after ADET was CR 18%, PR 44%, SD 21% and PD 18%. QoL was 90% PPS at each time point. Median time to progression for patients who progressed was 2.5 mo(range 0.8-6). Median follow-up was 14 mo(0.8-25 range). ADETs were performed with no complications. Observed side effects(mild or moderate intensity) were: Pain in 32% of patients, increase of transaminase levels in 20% and fever in 14%, whereas 30% of patients did not complain any adverse event. CONCLUSION The treatment of unresectable CRC-LM with ADET using polyethylene glycol microspheres loaded with irinotecan was effective in tumor response and resulted in mild toxicity, and good QoL.

文摘BACKGROUND Hepatic hemangioma is the most common benign tumor of the liver.However,patients with large hemangiomas that cause compression symptoms or that are at risk of rupture may need further intervention.It is necessary to explore additional minimally invasive and personalized treatment options for hemangiomas.CASE SUMMARY A 47-year-old woman was diagnosed with a right hepatic hemangioma for more than 10 years.Abdominal contrast-enhanced computed tomography(CT)and contrast-enhanced ultrasound revealed that there was a large hemangioma in the right liver,with a size of approximately 95 mm×97 mm×117 mm.Due to the patient's refusal of surgical treatment,hepatic artery embolization was performed in the first stage.After 25 d of liver protection treatment,the liver function indexes decreased to normal levels.Then,ultrasound-guided microwave ablation of the giant hepatic hemangioma was performed.Ten days after the treatment,hepatobiliary ultrasonography showed that the hemangioma of the right liver was smaller than the previous size(the volume was reduced by approximately 30%).Then the patient was discharged from the hospital.One year after discharge,CT showed that the hepatic hemangioma had shrunk by about 80%CONCLUSION Transcatheter arterial embolization combined with microwave ablation is a safe and effective minimally invasive treatment for hepatic hemangioma.

文摘BACKGROUND Despite the improvement in the endoscopic hemostasis of non-variceal upper gastrointestinal bleeding(NVUGIB),rebleeding remains a major concern.AIM To assess the role of prophylactic transcatheter arterial embolization(PTAE)added to successful hemostatic treatment among NVUGIB patients.METHODS We searched three databases from inception through October 19th,2020.Randomized controlled trials(RCTs)and observational cohort studies were eligible.Studies compared patients with NVUGIB receiving PTAE to those who did not get PTAE.Investigated outcomes were rebleeding,mortality,reintervention,need for surgery and transfusion,length of hospital(LOH),and intensive care unit(ICU)stay.In the quantitative synthesis,odds ratios(ORs)and weighted mean differences(WMDs)were calculated with the random-effects model and interpreted with 95%confidence intervals(CIs).RESULTS We included a total of 3 RCTs and 9 observational studies with a total of 1329 patients,with 486 in the intervention group.PTAE was associated with lower odds of rebleeding(OR=0.48,95%CI:0.29–0.78).There was no difference in the 30-d mortality rates(OR=0.82,95%CI:0.39–1.72)between the PTAE and control groups.Patients who underwent PTAE treatment had a lower chance for reintervention(OR=0.48,95%CI:0.31–0.76)or rescue surgery(OR=0.35,95%CI:0.14–0.92).The LOH and ICU stay was shorter in the PTAE group,but the difference was non-significant[WMD=-3.77,95%CI:(-8.00)–0.45;WMD=-1.33,95%CI:(-2.84)–0.18,respectively].CONCLUSION PTAE is associated with lower odds of rebleeding and any reintervention in NVUGIB.However,further RCTs are needed to have a higher level of evidence.

文摘Objective:This study aimed to introduce and evaluate a new embolization technique for the right gastric artery(RGA) during percutaneous implantation of a port-catheter system for hepatic arterial infusion chemotherapy(HAIC).Methods:From January 2013 to January 2017,159 patients with unresectable advanced liver cancer underwent percutaneous implantation of a port-catheter system.In 86 of these patients(56 men;aged 28-88 years;mean:60.6±12.0 years),in whom the RGA was obvious on arteriography,embolization of RGA was attempted using microcoils to protect the gastric mucosa during HAIC.In the first phase(first three years),antegrade embolization of the RGA using a 2.7 Fr microcatheter was performed in 55 patients.In the second phase(next two years),embolization of the RGA was attempted by combining antegrade embolization and retrograde embolization through the left gastric artery(LGA) in 31 patients.The success rates and the incidence of acute gastroduodenal mucosal toxicity(AGMT) in these two groups were compared.Results:The total success rate of the RGA embolization was 70.9%.The success rate was 83.9% in 31 patients who underwent combined antegrade and retrograde embolization,which was significantly higher than that of antegrade embolization alone(63.6%) performed in 55 patients(p=0.047).No complications related to embolization of RGA were documented.The incidence of AGMT was 29.1%(16/55) in patients in the first phase,which was significantly higher than that in the patients in the second phase(9.7%,3/31)(p=0.037).Conclusion: A combination of retrograde embolization via LGA could increase the success rates of RGA embolization and reduce the incidence of AGMT after HAIC.

文摘Objective:This study aimed to analyze the effects of transcatheter arterial embolization(TAE)combined with portal venous embolization(PVE)on the expression of MMP-2 in residual VX2 liver tumor tissues,liver function and non-embolic lobe regeneration.Methods:A total of 72 rabbits were randomly divided into Sham,TAE,PVE and TAE+PVE groups(n=18/group).The tissue samples from each group were taken at 6 h,3 days and 7 days after interventional operation,respectively.MMP-2 expression was detected by immunohistochemistry,Real-time PCR,and Western-blotting.The main indicators(such as AST,ATL,and TBIL)of liver function and the volume of non-embolized hepatic lobes were measured in each group after operation.One-way ANOVA and Kruskal-wallis method were used for statistical analysis.Results:The expression of MMP-2 mRNA and protein remained the highest in the Sham group,and the expression of MMP-2 mRNA and protein in TAE,PVE and TAE+PVE groups were successively increased,and the expression of MMP-2 in TAE+PVE group was always significantly higher than TAE group.The AST and ALT levels in each group on day 7 after operation showed a significant declination,and all groups have recovered to the preoperative baseline level and TBIL has a slight fluctuation in each group after operation with no statistical difference.On day 7 after operation,the increasing volume of non-embolized liver lobes in TAE+PVE group showed a more significant effect than those in PVE group,but there was no statistical significance(37.62±1.54 ml VS 36.18±1.15 ml,P=0.881),and its volume was significantly higher than those in the sham group(27.03±1.11 ml).Conclusion:TAE+PVE is considered to be an efficient and safe approach for treating rabbit VX2 liver transplantation tumor,but the expression of MMP-2 increased fastest after TAE+PVE,which might promote tumor cell invasion and metastasis.
