ABSTRACT
BACKGROUND: Budd-Chiari syndrome (BCS) results from the obstruction of the hepatic venous flow, usually at the level of the hepatic vein or inferior vena cava. When left untreated, it can progress with several complications, including liver cirrhosis. Transjugular intrahepatic portosystemic shunt (TIPS) appears to be effective in a subgroup of BCS patients. OBJECTIVE: To perform a systematic review and meta-analysis of TIPS effectiveness in BCS treatment, considering the survival rate, reduction in portosystemic pressure, need for liver transplantation, technical failure, and shunt dysfunction for up to 10 years of follow-up. METHODS: We evaluated 17 studies published in PubMed, Science Direct, Web of Science, and SCOPUS databases, which used TIPS as a treatment for BCS, comprising 618 subjects between 18 and 78 years old. We assessed the bias risk by the NOS, NHI, and JBI scales for cohort stu-dies, before-after studies, and case series, respectively. We conducted the meta-analyses by extracting the number of events and the total patients evaluated to perform the proportion meta-analyses using the R software ("meta" package - version 4.9-6). RESULTS: The pooled results (95%CI) showed a 19% (25.9-12.5%) rate of portosystemic pressure reduction, 6% (1-12%) rate for the need for liver transplants despite the use of TIPS, 2% (1-6%) technical failure rate, 30% (18-46%) shunt dysfunction rate, and 88% (81-93%) for the mean frequency of patients alive between 1 and 10 years after the procedure. We stratified survival rate and found an 86% (74-93%) prevalence of living subjects during less than five years, 92% (83-97%) at five years, and a 77% frequency (68-83%) of patients alive ten years after the TIPS placement. CONCLUSION: TIPS is an effective treatment for BCS, providing a high 10-year frequency of living patients and a significant decrease in portosystemic pressure. The need for liver transplants after TIPS and the technical failure rate is low.

In some specific cases, the surgical technique involved in liver transplantation can be challenging, as, for example, in cases of Budd-Chiari syndrome. This case describes a case of liver transplantation in a patient diagnosed with Budd-Chiari syndrome due to a previous surgery that required retrohepatic vena cava resection. During the liver transplantation procedure, a cavo-atrial anastomosis was performed through transdiaphragmatic access, with a good postoperative result, showing that, although challenging, this technique is a feasible option in specific cases.

Objective: To explore the risk factors of short-term prognosis of severe Budd-Chiari syndrome (BCS) patients,established and verified the nomogram prediction model for these BCS patients and evaluated its clinical application value. Methods: This study is a retrospective cohort study. The clinical data of 171 patients with severe BCS diagnosed were retrospectively analyzed in the Department of Hepatopancreatobiliary Surgery First Affiliated Hospital of Zhengzhou University from January 2018 to December 2023. There were 105 males and 66 females, aged (52.1±12.8) years (range: 18 to 79 years). The patients were divided into two groups based on whether they died within 28 days: the death group (n=38) and the survival group (n=133). The risk factors for short-term death of patients were analyzed,and independent risk factors were screened by univariate and multivariate analysis. Furthermore,these factors were used to establish the nomogram prediction model. The area under the curve(AUC),the Bootstrap Resampling,the Hosmer-Lemeshow test and the Decision Curve Analysis(DCA) were used to verify the model's differentiation,internal verification,calibration degree and clinical effectiveness,respectively. Results: Univariate and multivariate Logistics regression analysis showed that the history of hepatic encephalopathy,white blood cell,glomerular filtration rate and prothrombin time were independent risk factors (P<0.05). The above factors were used to successfully establish the prediction model with 0.908 of AUC and 0.895 of the internal verification of AUC,indicating that the predictive model was valuable. The 0.663 P-values in the Hosmer-Lemeshow test indicated the high calibration degree of the model. The clinical effectiveness of the model was proved by the 18% clinical benefit population using the DCA curve with the 17% probability threshold. Conclusions: The independent risk factors are the history of hepatic encephalopathy,white blood cell,glomerular filtration rate and prothrombin time. An adequate basis was acquired by establishing a nomogram prediction model of the short-term prognosis of severe BCS,which was helpful for early clinical screening and identification of high-risk patients with severe BCS who could die in the short term and timely providing timely intervention measures for improving the prognosis.

BACKGROUND AND AIMS: Management of Budd-Chiari syndrome (BCS) has improved over the last decades. The main aim was to evaluate the contemporary post-liver transplant (post-LT) outcomes in Europe. APPROACH AND RESULTS: Data from all patients who underwent transplantation from 1976 to 2020 was obtained from the European Liver Transplant Registry (ELTR). Patients < 16 years, with secondary BCS or HCC were excluded. Patient survival (PS) and graft survival (GS) before and after 2000 were compared. Multivariate Cox regression analysis identified predictors of PS and GS after 2000. Supplemental data was requested from all ELTR-affiliated centers and received from 44. In all, 808 patients underwent transplantation between 2000 and 2020. One-, 5- and 10-year PS was 84%, 77%, and 68%, and GS was 79%, 70%, and 62%, respectively. Both significantly improved compared to outcomes before 2000 ( p < 0.001). Median follow-up was 50 months and retransplantation rate was 12%. Recipient age (aHR:1.04,95%CI:1.02-1.06) and MELD score (aHR:1.04,95%CI:1.01-1.06), especially above 30, were associated with worse PS, while male sex had better outcomes (aHR:0.63,95%CI:0.41-0.96). Donor age was associated with worse PS (aHR:1.01,95%CI:1.00-1.03) and GS (aHR:1.02,95%CI:1.01-1.03). In 353 patients (44%) with supplemental data, 33% had myeloproliferative neoplasm, 20% underwent TIPS pre-LT, and 85% used anticoagulation post-LT. Post-LT anticoagulation was associated with improved PS (aHR:0.29,95%CI:0.16-0.54) and GS (aHR:0.48,95%CI:0.29-0.81). Hepatic artery thrombosis and portal vein thrombosis (PVT) occurred in 9% and 7%, while recurrent BCS was rare (3%). CONCLUSIONS: LT for BCS results in excellent patient- and graft-survival. Older recipient or donor age and higher MELD are associated with poorer outcomes, while long-term anticoagulation improves both patient and graft outcomes.

BACKGROUND: Living-donor liver transplantation (LDLT) is established as a standard therapy for end-stage liver disease; however, vessel reconstruction is more demanding due to the short length and small size of the available structures compared with deceased-donor whole liver transplantation. Interventional radiology (IR) has become the first-line treatment for vascular complications after LDLT. Hepatic venous outflow obstruction (HVOO) is a life-threatening complication after LDLT. The aim of this study of 592 adult-to-adult LDLT cases was to investigate the safety and efficacy of stent implantation for HVOO after LDLT. METHODS: Records of patients who developed HVOO requiring any treatment were collected with special reference to the metallic stent implantation. There were 232 left-side grafts and 360 right-side grafts. Sixteen cases developed HVOO after LDLT with an incidence rate of 2.7%, 5 with a left liver graft (2%), and 11 with a right-side graft (3%). The IR was attempted for 14 cases; among those, 8 cases were treated by stent implantation. RESULTS: The technical success rate of the initial stent implantation was 100%. The pressure gradient at the stenotic site significantly improved from 12.2 (range, 10.9-20.4 cm H2O) to 3.9 cm H2O (range, 1.4-8.2 cm H2O; P = .03). The volume of the congested graft liver decreased significantly from 1448 (range, 788-2170 mL) to 1265 mL (range, 748-1665 mL; P = .01), and the serum albumin level improved significantly from 3.3 (range, 1.7-3.7 g/dL) to 3.7 g/dL (range, 2.9-4.1 g/dL; P = .02). No procedure-related complication was noted, and the long-term stent patency was 100%. CONCLUSION: Metallic stent implantation for stenotic venous anastomosis after LDLT is a safe and effective treatment.

A 24-year-old man was admitted to our hospital with abdominal distension. He was found to have acute liver failure and diagnosed with Budd-Chiari syndrome based on angiography and liver biopsy. Liver transplantation was deemed necessary when angiography showed extensive thrombotic occlusion of the hepatic veins and liver biopsy revealed submassive hepatic necrosis. The patient was found to have the JAK2V617F mutation, indicating a myeloproliferative neoplasm as the background disease. He developed hepatic encephalopathy but remained conscious on on-line hemodiafiltration. Brain-dead donor liver transplantation was performed on hospital day 30. Since then, the patient has remained well.

A Japanese man in his 20s was referred to our hospital with a two-month history of abdominal fullness and leg edema. Abdominal computed tomography revealing massive ascites and ostial blockage of the main hepatic veins, and angiographic evaluation demonstrating obstruction of the main hepatic veins yielded a diagnosis of Budd-Chiari syndrome (BCS). Diuretic agents were prescribed for the ascites but failed to provide relief. The patient was referred to our department for further evaluation and treatment. Angiography showed ostial obstruction of the main hepatic veins, with most of the portal hepatic flow draining from an inferior right hepatic vein (IRHV) into the inferior vena cava (IVC) thorough an intrahepatic portal venous and venovenous shunt. Access between the main hepatic veins and IVC was impossible, but cannulation between the IRHV and IVC was achieved. Because of the venovenous connection between the main hepatic vein and the IRHV, metallic stents were placed into two IRHVs to decrease congestion in the hepatic venous outflow. After stent placement followed by balloon expansion, the gradient pressure between the hepatic vein and IVC improved remarkably. The ascites and lower leg edema improved postoperatively, and long-term stent patency (6 years) was achieved.

INTRODUCTION: In pediatric patients with Budd-Chiari syndrome (BCS), living donor liver transplantation (LDLT) raises substantial challenges regarding IVC reconstruction. CASE PRESENTATION: We present a case of an 8-year-old girl with BCS caused by myeloproliferative syndrome with JAK2 V617F mutation. She had a complete thrombosis of the inferior vena cava (IVC) with multiple collaterals, developing a Budd-Chiari syndrome. She underwent LDLT with IVC reconstruction with a cryopreserved pulmonary vein graft obtained from a provincial biobank. The living donor underwent a laparoscopic-assisted left lateral hepatectomy. The reconstruction of the vena cava took place on the back table and the liver was implanted en bloc with the reconstructed IVC in the recipient. Anticoagulation was immediately restarted after the surgery because of her pro-thrombotic state. Her postoperative course was complicated by a biliary anastomotic leak and an infected biloma. The patient recovered progressively and remained well on outpatient clinic follow-up 32 weeks after the procedure. CONCLUSION: IVC reconstruction using a cryopreserved pulmonary vein graft is a valid option during LDLT for pediatric patients with BCS where reconstruction of the IVC entails considerable challenges. Early referral to a pediatric liver transplant facility with a multidisciplinary team is also important in the management of pediatric patients with BCS.

OBJECTIVE: To present the early results of a new technique for the treatment of renal cell carcinoma with intra-cardiac tumour extension and Budd-Chiari syndrome. PATIENTS AND METHODS: The first stage involves transdiaphragmatic debulking of the right heart, inferior vena cava (IVC) and hepatic veins via median sternotomy, followed by a purse-string suture placed in the IVC below the hepatic veins. The second stage is performed separately and involves en bloc resection of the affected kidney, and IVC and vascular reconstruction via an abdominal incision. RESULTS: Three of five patients presented with clinical Budd-Chiari syndrome; two had radiological features only. The median time between surgical procedures was 12 days (IQR 13 days). Four of the five patients had a R0 resection. While all five patients successfully completed both operative stages, one patient died 22 days after the second stage. Of the remaining four, all survive with no disease recurrence. CONCLUSION: While we continue to compile longer-term data for a larger follow-up series, these preliminary findings show the feasibility of this technique and support the development of this programme of surgery.

We report the case of a male patient who had a history of early-onset protein-losing enteropathy, chronic diarrhea, and repeated thrombotic events since early childhood. He developed Budd-Chiari syndrome with consequent acute liver failure that required liver transplantation when he was 12 years old. The initial graft failed to function and he required retransplantation. Steroid-resistant rejection complicated the clinical course after the second transplant. Treatment with antithymocyte globulin stabilized graft function but abdominal symptoms and enteral protein loss persisted. The patient remained dependent on intravenous albumin and immunoglobulin. Extended work-up for thrombophilia was unremarkable. Flow cytometry analysis of the peripheral blood cells revealed an unexplained CD55 deficiency. By sequencing of CD55 and, later, exclusion of alternative rare diseases by whole-exome sequencing, we discovered a novel, likely pathogenic homozygous splice-site variant in CD55 c.578 + 5G>A, NM_000574.4, OMIM 125240. The staining of liver and colon biopsies revealed a lack of CD55 protein expression. After initiation of treatment with eculizumab, the patient achieved and has maintained a complete clinical remission throughout 56 months of follow-up. We recommend testing for CD55 deficiency in patients with protein-losing enteropathy. In addition, CD55 deficiency should be considered in the differential diagnosis of patients with Budd-Chiari syndrome in whom an underlying cause is uncertain.

BACKGROUND: Budd-Chiari syndrome (BCS) results when the outflow of the hepatic vein (HV) is obstructed. BCS patients exhibiting an accessory HV (AHV) that is dilated but obstructed can achieve significant alleviation of liver congestion after undergoing AHV recanalization. This meta-analysis was developed to explore the clinical efficacy of AHV recanalization in patients with BCS. MATERIALS AND METHODS: PubMed, Embase, and Wanfang databases were searched for relevant studies published as of November 2022, and RevMan 5.3 and Stata 12.0 were used for pooled endpoint analyses. RESULTS: Twelve total studies were identified for analysis. Pooled primary clinical success, re-stenosis, 1- and 5-year primary patency, 1- and 5-year secondary patency, 1-year overall survival (OS), and 5-year OS rates of patients in these studies following AHV recanalization were 96%, 17%, 91%, 75%, 98%, 91%, 97%, and 96%, respectively. Patients also exhibited a significant reduction in AHV pressure after recanalization relative to preoperative levels (P < 0.00001). Endpoints exhibiting significant heterogeneity among these studies included, AHV pressure (I2 = 95%), 1-year primary patency (I2 = 51.2%), and 5-year primary patency (I2 = 62.4%). Relative to HV recanalization, AHV recanalization was related to a lower rate of re-stenosis (P = 0.002) and longer primary patency (P < 0.00001), but was not associated with any improvements in clinical success (P = 0.88) or OS (P = 0.29) relative to HV recanalization. CONCLUSIONS: The present meta-analysis highlights AHV recanalization as an effective means of achieving positive long-term outcomes in patients affected by BCS, potentially achieving better long-term results than those associated with HV recanalization.

BACKGROUND: Significant variations exist regarding the definition of difficult liver transplantation. The study goals were to investigate how liver transplant surgeons evaluate the surgical difficulty of liver transplantation and to use the identified factors to classify liver transplantation difficulty. METHODS: A Web-based online European survey was presented to liver transplant surgeons. The survey was divided into 3 parts: (1) participant demographics and practices; (2) various situations based on recipient, liver disease, tumor treatment, and technical factors; and (3) 8 real-life clinical vignettes with different levels of complexity. In part 3 of the survey, respondents were asked whether they would perform liver transplantation but were not aware that these patients eventually underwent liver transplantation. RESULTS: A total of 143 invites were sent out, and 97 (67.8%) participants completed the survey. Most participants considered previous spontaneous bacterial peritonitis, previous supra-mesocolic surgery, hypertrophy of segment I, and obesity to be recipient factors for high-difficulty liver transplantation. Most participants considered liver transplantation to be challenging in patients with Budd-Chiari syndrome, Kasai surgery, polycystic liver disease, diffuse portal vein thrombosis, and a history of open hepatectomy. The proportion of participants indicating that liver transplantation was warranted varied across the 8 cases, from 69% to 100%. Our classification of the surgical difficulty of liver transplantation employed these recipient-related, surgical history-related, and liver disease-related variables and 3 difficulty groups were identified: low, intermediate, and high difficulty groups. CONCLUSION: This survey provides an overview of the surgical difficulty of various situations in liver transplantation that could be useful for further benchmark and textbook outcome studies.

Anticoagulants are the first-line treatment option for patients with Budd-Chiari syndrome (BCS); however, intervention is required when this fails. Although, the ultimate treatment is liver transplant, other radiological procedures are for the management of the disease and bridge to definitive therapy. TIPS (trans jugular intrahepatic portosystemic shunt) is a method used by interventional radiologists to create a shunt between portal vein and hepatic vein. At times it is technically not possible, in such cases, direct intrahepatic portosystemic shunt (DIPS) is performed. This patient underwent a successful DIPS procedure for BCS along with balloon dilatation (venoplasty) for inferior vena cava (IVC) stenosis.

BACKGROUND: Budd-Chiari syndrome (BCS) is a rare vascular disorder of the liver, and acute and secondary BCS is even rarer. CASE PRESENTATION: A 62-year-old man with perihilar cholangiocarcinoma of Bismuth type IIIa underwent right hemi-hepatectomy with caudate lobectomy and pancreatoduodenectomy. Adjuvant chemoradiotherapy was performed due to a positive hepatic ductal margin. Subsequently, the disease passed without recurrence. The patient visited for acute onset abdominal pain at the 32nd postoperative month. Multidetector-row computed tomography (MDCT) showed stenosis of the left hepatic vein (LHV) root, which was the irradiated field, and thrombotic occlusion of the LHV. The patient was diagnosed with acute BCS caused by adjuvant radiotherapy. Although anticoagulation therapy was performed, the patient complained of sudden upper abdominal pain again. MDCT showed an enlarged LHV thrombus and hepatomegaly. The patient was diagnosed with exacerbated acute BCS, and stenting for the stenotic LHV root was performed with a bare stent. Although stenting for the LHV root was very effective, restenosis occurred twice due to thrombus in the existing stent, so re-stenting was performed twice. The subsequent clinical course was acceptable without recurrence or restenosis of the LHV root as of 6 months after the last stenting using a stent graft. CONCLUSION: Although no case of BCS caused by radiotherapy has yet been reported, the present case showed that late side effect of radiotherapy can cause hepatic vein stenosis and secondary BCS.

PURPOSE: This study was designed to assess the clinical efficiency and long-term outcomes of hepatic vein (HV) and accessory hepatic vein (AHV) recanalization in patients with HV-type Budd-Chiari syndrome (BCS). MATERIAL AND METHODS: A total of 27 patients with HV-type BCS underwent AHV recanalization and 94 patients had HV recanalization at our center from January 2012 to December 2019. The treatment effectiveness and long-term outcomes were compared. RESULTS: Technical success was accomplished in all patients, without any procedure-related complications. The clinical success rates were 96.3% (26/27) and 95.7% (90/94) (p = 1.000). In the AHV and HV groups, re-obstruction was observed in 5 and 36 patients, respectively (p = 0.056). The median primary durations of AHV and HV patency were 64 and 49 months, respectively (p = 0.036), while the median secondary durations of AHV and HV patency were 70 and 64 months, respectively (p = 0.134). The median overall survival after AHV and HV recanalization was 73 and 78 months, respectively (p = 0.263). CONCLUSIONS: Our findings suggest that AHV could be employed as a replacement for HV, as a hepatic drainage vein, in HV-type BCS patients.

PURPOSE: To evaluate the changes in the liver volume and function after direct intrahepatic portocaval shunt (DIPS) in patients with Budd-Chiari syndrome (BCS) with diffuse hepatic vein (HV) occlusion. METHODS: The clinical data of 29 patients with BCS who underwent DIPS for intractable ascites caused by diffuse hepatic vein occlusion in the Affiliated Hospital of Xuzhou Medical University were analysed retrospectively; the patients included 8 males and 21 females, with an average age of 33.3 ± 6.3 years. The patients underwent abdominal CT scanning and liver function examinations before DIPS, and 1 week, 3 months, 6 months and 12 months after DIPS. The changes of the liver volume and liver function before and after DIPS were compared. RESULTS: All 29 patients underwent DIPS successfully. 28 patients survived during the follow-up of 12-33 months, with a median follow-up of 16 months. The patients' liver function were significantly improved at 3, 6 and 12 months after the operation compared to before the operation (P < 0.05). The liver volumes measured before the operation and 1 week, 3 months, 6 months and 12 months after the operation were 2124.586 ± 420.889 cm3, 1926.263 ± 372.268 cm3, 1480.592 ± 183.061 cm3, 1461.904 ± 153.027 cm3 and 1469.286 ± 148.549 cm3, respectively. Compared with the preoperative liver volume, the liver volume had decreased significantly at 1 week, 3 months, 6 months and 12 months after the operation (P < 0.05). However, there was no significant difference in the liver volumes at 6 and 12 months after the operation (P = 0.35). CONCLUSIONS: Direct intrahepatic portocaval shunt has achieved satisfactory clinical results in the treatment of BCS with diffuse hepatic vein occlusion. The congestive hepatomegaly was gradually reduced after the operation. The liver volume (which was defined as the clinical efficacy in this study) remained stable after 6 months.

OBJECTIVE: Inferior vena cava (IVC) stenting may provide benefit to patients with symptomatic obstruction; however, there are no devices currently licensed for use in the IVC and systematic reviews on the topic are lacking. The aim of this study was to carry out a systematic review of the literature and meta-analysis to investigate the safety and efficacy of IVC stenting in all adult patient groups. DATA SOURCES: The Medline and Embase databases were searched for studies reporting outcomes for safety and effectiveness of IVC stenting for any indication in series of 10 or more patients. REVIEW METHODS: A systematic review of the literature was carried out according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. RESULTS: Thirty-three studies were included describing 1 575 patients. Indications for stenting were malignant IVC syndrome (229 patients), thrombotic disease (807 patients), Budd-Chiari syndrome (501 patients), and IVC stenosis post liver transplantation (47 patients). The male:female ratio was 2:1 and the median age ranged from 30 to 61 years. The studies included were not suitable for formal meta-analysis as 30/33 were single centre retrospective studies with no control groups and there was considerable inconsistency in outcome reporting. There was significant risk of bias in 94% of studies. Median reported technical success was 100% (range 78 - 100%), primary patency was 75% (38 - 98%), and secondary patency was 91.5% (77 - 100%). Major complications were pulmonary embolism (three cases), stent migration (12 cases), and major bleeding (15 cases), and there were three deaths in the immediate post-operative period. Most studies reported improvement in clinical symptoms but formal reporting tools were not used consistently. CONCLUSION: The evidence base for IVC stenting consists of predominantly single centre, retrospective, observational studies that have a high risk of bias. Nonetheless the procedure appears safe with few major adverse events, and studies that reported clinical outcomes demonstrate improvement in symptoms and quality of life. Randomised controlled trials and prospective registry based studies with larger patient numbers and standardised outcome are required to improve the evidence base for this procedure.
