Objective: To investigate the effects of preoperative hepatic artery chemoembolization (TACE) and quality nursing interventions on the perioperative safety and short-term prognosis in patients with hepatocellular carcinoma undergoing liver transplantation. Methods: The study period spanned from January 2021 to December 2023, and 125 patients with hepatocellular carcinoma admitted to our hospital were selected, all of whom underwent liver transplantation. They were randomly divided into an observation group (n = 63) and a control group (n = 62). The patients in the control group did not undergo TACE before the operation, and the patients in the observation group underwent TACE and quality nursing intervention before the operation. The operation time, intraoperative blood loss, length of hospitalization, liver- free period, complication rate, short-term prognosis, and liver function indexes between the two groups were compared. Results: There was no significant difference in operation time, intraoperative blood loss, and length of hospitalization between the two groups (P < 0.05). The liver-free period of patients in the observation group was longer than that of the control group (P < 0.05). The two groups had no significant difference in the incidence of biliary complications, vascular complications, and postoperative infections (P > 0.05). The rate of immune reactive complications in the observation group was lower than that of the control group (P < 0.05). There was no significant difference in the perioperative mortality rate, 1-year postoperative survival rate, and 2-year postoperative survival rate (P > 0.05). The two groups had no significant difference in postoperative liver function indexes (P > 0.05). Conclusion: Preoperative TACE and high-quality nursing intervention in patients with hepatocellular carcinoma had no adverse effect on the perioperative safety and short-term prognosis, prolonged the liver-free time, and reduced the incidence of immune-reactive complications. 展开更多

BACKGROUND:Portal vein embolization not only induces hypertrophy of the non-embolized liver,but also enhances tumor growth.The latter could be prevented by embolizing the hepatic arteries supplying the tumor-bearing liver segments.This study aimed to determine the effects of transcatheter arterial embolization(TAE)on tumor volume and liver regeneration in a rabbit VX2 tumor model.METHODS:Twenty-three rabbits underwent subcapsular tumor implantation with a VX2 tumor.Two weeks after implantation,18 rabbits were used for TAE experiments,5were for sham controls.Tumor response and liver regeneration response of the embolized cranial and non-embolized caudal liver lobes were assessed by CT volumetry,liver to body weight index,and the amount of proliferating hepatocytes.RESULTS:All super-selective arterial tumor embolization procedures were performed successfully.Despite embolization,the tumor volume increased after an initial steady state.The tumor volume after embolization was smaller than that of the sham group,but this difference was not significant.Massive necrosis of the tumor,however,was seen after embolization,without damage of the surrounding liver parenchyma.There was a significant atrophy response of the tumor bearing cranial lobe after super-selective arterial embolization of the tumor with a concomitant hypertrophy response of the non-embolized,caudal lobe.This regeneration response was confirmed histologically by a significantly higher number of proliferating hepatocytes on the Ki-67 stained slides.CONCLUSIONS:Super-selective,bland arterial coil embolization causes massive necrosis of the tumor,despite increase of volume on CT scan.Atrophy of the tumor bearing liver lobe is seen after arterial embolization of the tumor with a concomitant hypertrophy response of the non-embolized lobe,despite absence of histological damage of the tumor-surrounding liver parenchyma. 展开更多

We herein report a case of a hilar tumor with extensive invasion to the proper hepatic artery, which was successfully treated with a radical resection in a 57-year-old female patient after a stepwise hepatic arterial embolization. She underwent right colectomy and partial hepatectomy for advanced colon cancer two years ago and radiofrequency ablation therapy for a liver metastasis one year ago, respectively. A recurrent tumor was noted around the proper hepatic artery with invasion to the left hepatic duct and right hepatic artery 7 mo previously. We planned a radical resection for the patient 5 mo after the absence of tumor progression was confirmed while he was undergoing chemotherapy. To avoid surgery-related liver failure, we tried to promote the formation of collateral hepatic arteries after stepwise arterial embolizationof the posterior and anterior hepatic arteries two weeks apart. Finally, the proper hepatic artery was occluded after formation of collateral flow from the inferior phrenic and superior mesenteric arteries was confirmed. One month later, a left hepatectomy with hepatic arterial resection was successfully performed without any major complications. 展开更多

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. 展开更多

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. 展开更多

AIM: To observe the dynamic changes of liver microcirculation in vivo after arterial embolization with degradable starch microspheres (DSM). METHODS: DSM were injected into the proper hepatic artery through a silastic tube inserted retrogradely in gastroduodenal artery (GDA) of SD rats. Fluorescent microscopy was used to evaluate the dynamic changes of blood flow through the terminal portal venules (TPVs), sinusoids and terminal hepatic venules (THVs). The movements of DSM debris were also recorded. Six hours after injection of DSM, percentages of THVs with completely stagnant blood flow were recorded. RESULTS: Two phases of blood flow change were recorded. In phase one: after intra-arterial injection of DSM, slow or stagnant blood flow was immediately recorded in TPVs, sinusoids and THVs. This change was reversible, and blood flow resumed completely. In phase two: after phase one, blood flow in TPVs changed again and three patterns of blood flow were recorded. Six hours after DSM injection, 36.9% ± 9.2% of THVs were found with completely stagnant blood flow. CONCLUSION: DSM can stop the microcirculatory blood flow in some areas of liver parenchyma. Liver parenchyma supplied by arteries with larger A-P shunt is considered at a higher risk of total microcirculatory blood stagnation after injection of DSM through hepatic artery. 展开更多

Purpose: To assess the efficacy of endovascular management for ruptured hepatic artery pseudoaneurysm (HAP). Methods: Six cases of HAP in five patients (four men and one women;mean age, 50;range, 28 - 62) were treated with transcatheter arterial coil embolization using microcoil (Boston Scientific, Watertown, MA, USA) and Tornado Coil (Cook, Bloomington, IN, USA) with or without stent graft between January 2007 and September 2008. They were analyzed with regard to the clinical presentation, radiological findings with procedure, and clinical and radiologic outcomes. Results: All patients presented with epigastric pain or gastrointestinal bleeding. The pseudoaneurysms were ranged from 0.6 to 4.4 cm in size and located in the common hepatic artery (n = 1), junction between proper and right hepatic artery (n = 1), proper hepatic artery (n = 2), the left hepatic artery (n = 1), right hepatic artery (n = 1). Embolization was performed with microcoils in all pseudoaneurysmal sac with or without both afferent and efferent segment. A self-expandable stent (n = 1) was also used. Overall technical success was 100% (6 of 6) and complete occlusions of HAPs were achieved in 5 out of 6 cases, 83.3% of clinical success rate. Re-bleeding occurred in one case of stent graft at proper hepatic artery following coil packing for pseudoaneurysmal sac. Clinical success rate of embolization for both afferent and efferent segment was 100% (3 of 3). Procedure-related minor complications happened in 2 of 5 patients, and they were treated conservatively. Conclusion: Transcatheter coil embolization for ruptured HAP is sufficiently effective and additional embolization in both afferent segment and efferent segment can improve clinical success rate. 展开更多

Post-traumatic hepatic artery pseudoaneurysm is unc-ommon,appearing in approximately 1%of hepatic trauma cases.Most are extrahepatic(80%)and have a late onset.Although they are usually asymptomatic, they should always be treated becasue of the high risk of complications,especially breakage.Currently the treatment of choice is endovascular embolization with coils or the exclusion of the pseudoaneurysm using other intravascular devices.Recently there have been accounts of a treatment that combines embolization with coils and image-guided percutaneous human thrombin injection.We present a case of post-traumatichepatic artery pseudoaneurysm that was successfully treated using this combined technique. 展开更多

Several strategies for treatment of pseudoaneurysms have been described. We describe a challenging case in which a small bleeding hepatic artery pseudoaneurysm is complicated by a proximal hepatic arterial occlusion, preventing transcatheter access. The aneurysm was too small to be seen on ultrasound. Using combined angiographic and fluoroscopic guidance, however, the aneurysm was triangulated and successfully treated with percutaneous direct thrombin injection. Combined angiography and fluoroscopy guided percutaneous thrombin injection of intrahepatic pseudoaneurysms can be a valuable treatment approach, particularly when other methods are not feasible or have failed. 展开更多

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. 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

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. 展开更多

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. 展开更多

BACKGROUND Prostatic artery embolization(PAE)is a promising but also technically demanding interventional radiologic treatment for symptomatic benign prostatic hyperplasia.Many technical challenges in PAE are associated with the complex anatomy of prostatic arteries(PAs)and with the systematic attempts to catheterize the PAs of both pelvic sides.Long procedure times and high radiation doses are often the result of these attempts and are considered significant disadvantages of PAE.The authors hypothesized that,in selected patients,these disadvantages could be mitigated by intentionally embolizing PAs of only one pelvic side.AIM To describe the authors’approach for intentionally unilateral PAE(IU-PAE)and its potential benefits.METHODS This was a single-center retrospective study of patients treated with IU-PAE during a period of 2 years.IU-PAE was applied in patients with opacification of more than half of the contralateral prostatic lobe after angiography of the ipsilateral PA(subgroup A),or with markedly asymmetric prostatic enlargement,with the dominant prostatic lobe occupying at least two thirds of the entire gland(subgroup B).All patients treated with IU-PAE also fulfilled at least one of the following criteria:Severe tortuosity or severe atheromatosis of the pelvic arteries,non-visualization,or visualization of a tiny(<1 mm)contralateral PA on preprocedural computed tomographic angiography.Intraprocedural contrast-enhanced ultrasonography(iCEUS)was applied to monitor prostatic infarction.IU-PAE patients were compared to a control group treated with bilateral PAE.RESULTS IU-PAE was performed in a total 13 patients(subgroup A,n=7;subgroup B,n=6).Dose-area product,fluoroscopy time and operation time in the IU-PAE group(9767.8μGy∙m^(2),30.3 minutes,64.0 minutes,respectively)were significantly shorter(45.4%,35.9%,45.8%respectively,P<0.01)compared to the control group.Clinical and imaging outcomes did not differ significantly between the IU-PAE group and the control group.In the 2 clinical failures of IU-PAE(both in subgroup A),the extent of prostatic infarction(demonstrated by iCEUS)was significantly smaller compared to the rest of the IU-PAE group.CONCLUSION In selected patients,IU-PAE is associated with comparable outcomes,but with lower radiation exposure and a shorter procedure compared to bilateral PAE.iCEUS could facilitate patient selection for IU-PAE. 展开更多

BACKGROUND The advent of cutting-edge systemic therapies has driven advances in the treatment of hepatocellular carcinoma(HCC),and therapeutic strategies with multiple modes of delivery have been shown to be more efficacious than mono-therapy.However,the mechanisms underlying this innovative treatment modality have not been elucidated.AIM To evaluate the clinical efficacy of targeted therapy plus immunotherapy combined with hepatic arterial infusion chemotherapy(HAIC)of FOLFOX in patients with unresectable HCC.METHODS We enrolled 53 patients with unresectable HCC who received a combination of targeted therapy,immunotherapy,and HAIC of FOLFOX between December 2020 and June 2021 and assessed the efficacy and safety of the treatment regimen.RESULTS The objective response rate was 60.4%(32/53),complete response was 24.5%(13/53),partial response was 35.9%(19/53),and stable disease was 39.6%(21/53).The median duration of response and median progression-free survival were 9.1 and 13.9 months,respectively.The surgical conversion rate was 34.0%(18/53),and 1-year overall survival was 83.0%without critical complicating diseases or adverse events(AEs).CONCLUSION The regimen of HAIC of FOLFOX,targeted therapy,and immunotherapy was curative for patients with unresectable HCC,with no serious AEs and a high rate of surgical conversion. 展开更多

Hepatic artery thrombosis(HAT)is a devastating vascular complication following liver transplantation,requiring prompt diagnosis and rapid revascularization treatment to prevent graft loss.At present,imaging modalities such as ultrasound,computed tomography,and magnetic resonance play crucial roles in diagnosing HAT.Although imaging techniques have improved sensitivity and specificity for HAT diagnosis,they have limitations that hinder the timely diagnosis of this complication.In this sense,the emergence of artificial intelligence(AI)presents a transformative opportunity to address these diagnostic limitations.The development of machine learning algorithms and deep neural networks has demonstrated the potential to enhance the precision diagnosis of liver transplant complications,enabling quicker and more accurate detection of HAT.This article examines the current landscape of imaging diagnostic techniques for HAT and explores the emerging role of AI in addressing future challenges in the diagnosis of HAT after liver transplant. 展开更多

BACKGROUND Hepatic arterial infusion chemotherapy and camrelizumab plus apatinib(TRIPLET protocol)is promising for advanced hepatocellular carcinoma(Ad-HCC).However,the usefulness of microwave ablation(MWA)after TRIPLET is still controversial.AIM To compare the efficacy and safety of TRIPLET alone(T-A)vs TRIPLET-MWA(TM)for Ad-HCC.METHODS From January 2018 to March 2022,217 Ad-HCC patients were retrospectively enrolled.Among them,122 were included in the T-A group,and 95 were included in the T-M group.A propensity score matching(PSM)was applied to balance bias.Overall survival(OS)was compared using the Kaplan-Meier curve with the log-rank test.The overall objective response rate(ORR)and major complications were also assessed.RESULTS After PSM,82 patients were included both the T-A group and the T-M group.The ORR(85.4%)in the T-M group was significantly higher than that(65.9%)in the T-A group(P<0.001).The cumulative 1-,2-,and 3-year OS rates were 98.7%,93.4%,and 82.0%in the T-M group and 85.1%,63.1%,and 55.0%in the T-A group(hazard ratio=0.22;95%confidence interval:0.10-0.49;P<0.001).The incidence of major complications was 4.9%(6/122)in the T-A group and 5.3%(5/95)in the T-M group,which were not significantly different(P=1.000).CONCLUSION T-M can provide better survival outcomes and comparable safety for Ad-HCC than T-A. 展开更多
