Budd-Chiari syndrome

Experts consensus on Chinese nomenclature of Budd-Chiari syndrome

In China, Budd-Chiari syndrome has been transliterated into six names according to the pronunciation of the letters. To standardize and unify the Chinese names of the disease, multi-disciplinary experts suggest translating Budd-Chiari syndrome into hepatic vein inferior venal cava obstruction syndrome as its Chinese name after reaching a consensus through discussion.

Budd-Chiari syndrome as a complication of eosinophilic granulomatosis with polyangiitis in a young Chinese man: a case report

Hepatic vein thrombosis is a rare occurrence in the clinical course of eosinophilic granulomatosis with polyangiitis (EGPA). The major mechanism of thrombosis has been postulated to involve the release of toxic proteins from eosinophils. A 36-year-old man with EGPA was admitted to our hospital in July 2018 with hematemesis and melena. Findings on physical examination included ascites and pigmentation of the lower extremities. Ultrasonography of the hepatic vein and inferior vena cava showed an obstruction of the hepatic vein. Magnetic resonance imaging showed low enhancement in the right hepatic vein region. At 34 years of age, the patient's EGPA had initially presented as asthma with eosinophilia (white blood cell count of 11.46 × 10¹²/L with 14.6% eosinophils). His skin biopsy showed infiltration of inflammatory cells and eosinophils, especially around medium-sized vessels, which was consistent with EGPA. The patient was thus diagnosed with Budd-Chiari syndrome associated with EGPA.

Transjugular intrahepatic portosystemic shunt for Budd-Chiari syndrome: A comprehensive review

Budd-Chiari syndrome (BCS) is a relatively rare clinical condition with a wide range of symptomatology, caused by the obstruction of the hepatic venous outflow. If left untreated, it has got an high mortality rate. Its management is based on a step-wise approach, depending on the clinical presentation, and includes different treatment from anticoagulation therapy up to Interventional Radiology techniques, such as transjugular intrahepatic portosystemic shunt (TIPS). TIPS is today considered a safe and highly effective treatment and should be recommended for BCS patients, including those awaiting orthotopic liver transplantation. In this review the pathophysiology, diagnosis and treatment options of BCS are presented, with a special focus on published data regarding the techniques and outcomes of TIPS for the treatment of BCS. Moreover, unresolved issues and future research will be discussed.

Anatomic Recanalization of Hepatic Vein and Inferior Vena Cava versus Direct Intrahepatic Portosystemic Shunt Creation in Budd-Chiari Syndrome: Overall Outcome and Midterm Transplant-Free Survival

PURPOSE

To assess overall outcome and midterm transplant-free survival of patients with Budd-Chiari syndrome (BCS) undergoing radiologic interventions including anatomic recanalization of the hepatic vein (HV) and inferior vena cava (IVC) and direct intrahepatic portosystemic shunt (DIPS) creation, both as combined and as independent groups.

MATERIALS AND METHODS

From November 2010 to October 2014, 136 patients with BCS were treated with HV/IVC recanalization (group 1) or DIPS creation (group 2). Both groups were periodically analyzed for stent patency on Doppler ultrasound, clinical outcome, biochemical parameters, and survival until death, liver transplantation, or last clinical evaluation.

RESULTS

Actuarial transplant-free survival for the entire cohort was 94% at 1 year and 5 years with no significant difference in overall survival. There was significant biochemical improvement in group 1 with decrease in mean serum bilirubin level (1.8 mg/dL to 1.4 mg/dL, P < .011), mean serum aspartate aminotransferase (48.6 IU/L to 33.2 IU/L, P < .05), and mean serum alanine aminotransferase (38.7 IU/L to 28.5 IU/L) and increase in mean serum albumin level (3.2 g/dL to 3.45 g/dL, P < .001) after 3 and 24 months. There were 4 deaths in each group at 1-year follow-up; all 4 patients had acute fulminant BCS at presentation.

CONCLUSIONS

Radiologic interventions for BCS lead to remarkable improvement of liver function and a good overall outcome and midterm transplant-free survival. Patients receiving anatomic recanalization show improved liver synthetic functions compared with patients treated with DIPS.

Endovascular treatment of Budd-Chiari syndrome: Single center experience

BACKGROUND AND AIM

Percutaneous radiologic interventions are increasingly being used in management of Budd-Chiari syndrome (BCS). Minimal invasive approach has resulted in excellent long-term outcomes. We evaluated the treatment efficacy and safety of radiological intervention in patients with BCS.

METHODS

Between January 2008 and June 2014, 190 patients with BCS underwent endovascular procedures (hepatic vein, collateral vein or inferior vena cava [IVC] plasty with or without stenting, or transjugular intrahepatic portosystemic shunting [TIPSS]). Clinical features, biochemical profile, and stent patency were monitored pre-procedure and post-procedure, and for a median duration of 42 (12-88) months.

RESULTS

Of 190 patients (mean [SD] age = 26.9 [11.5] years; 102 men), imaging revealed hepatic vein obstruction in 147 patients, IVC obstruction in 40 patients, and concomitant hepatic vein and IVC obstruction in three patients. At presentation, the radiological interventions included hepatic vein plasty/stenting in 38 patients, collateral vein stenting in three patients, IVC plasty/stenting in 40 patients, both IVC and hepatic vein stenting in three patients, and TIPSS in 106 patients. Response was seen in 153 patients (80.5%). Repeat interventions were required in 19 patients (10.0%). Complications were noted in nine patients (4.7%).

CONCLUSION

Our study demonstrates that venous recanalization and TIPSS for BCS are safe and efficacious.

Increased prevalence of heparin-induced thrombocytopenia in patients with Budd-Chiari syndrome: a retrospective analysis

BACKGROUND

Budd-Chiari syndrome (BCS) is a rare, potentially fatal disease characterized by hepatic venous outflow tract obstruction. Heparin-induced thrombocytopenia (HIT) is an immune-mediated complication of heparin therapy, with mortality approaching 10%. The reported prevalence of HIT in adults is 0.2-5.2%. Expert consensus through case reports is the only existing evidence of HIT in BCS. To our knowledge, this is the first study to formalize this anecdotal evidence.

METHODS

A retrospective analysis was carried out of patients presenting at a tertiary liver centre with acute liver failure because of BCS or BCS as the primary indication for liver transplantation between 2000 and 2013. The prevalence of HIT in the study group was compared with the highest reported prevalence in adult medical patients receiving heparin (5.2%). Mortality, length of stay and liver transplantation rates were also studied.

RESULTS

Of 32 BCS patients, 9 (28.1%) developed HIT, significantly higher than the previously reported prevalence of HIT in medical patients (5.2%) (P<0.0001). There was no difference in mortality (P=0.66), length of stay (P=0.58) and liver transplantation rate (P=0.39) between HIT-positive and HIT-negative patients.

CONCLUSION

The prevalence of HIT (28.1%) in our cohort of BCS patients is significantly higher than that in the general population (0.2-5.2%). Although this study was not powered to detect outcome differences, as heparin is the mainstay of acute BCS treatment, this represents a significant risk. We recommend a high index of suspicion for HIT in patients with BCS and thrombocytopenia, an appropriate HIT-testing strategy and consideration of direct thrombin inhibitors.

Imaging Diagnosis of Splanchnic Venous Thrombosis

Splanchnic vein thrombosis (SVT) is a broad term that includes Budd-Chiari syndrome and occlusion of veins that constitute the portal venous system. Due to the common risk factors involved in the pathogenesis of these clinically distinct disorders, concurrent involvement of two different regions is quite common. In acute and subacute SVT, the symptoms may overlap with a variety of other abdominal emergencies while in chronic SVT, the extent of portal hypertension and its attendant complications determine the clinical course. As a result, clinical diagnosis is often difficult and is frequently reliant on imaging. Tremendous improvements in vascular imaging in recent years have ensured that this once rare entity is being increasingly detected. Treatment of acute SVT requires immediate anticoagulation. Transcatheter thrombolysis or transjugular intrahepatic portosystemic shunt is used in the event of clinical deterioration. In cases with peritonitis, immediate laparotomy and bowel resection may be required for irreversible bowel ischemia. In chronic SVT, the underlying cause should be identified and treated. The imaging manifestations of the clinical syndromes resulting from SVT are comprehensively discussed here along with a brief review of the relevant clinical features and therapeutic approach.

Diagnosis and management of Budd Chiari syndrome: an update

Imaging plays a crucial role in the early detection and assessment of the extent of disease in Budd Chiari syndrome (BCS). Early diagnosis and intervention to mitigate hepatic congestion is vital to restoring hepatic function and alleviating portal hypertension. Interventional radiology serves a key role in the management of these patients. The interventionist should be knowledgeable of the clinical presentation as well as key imaging findings, which often dictate the approach to treatment. This article concisely reviews the etiology, pathophysiology, and clinical presentation of BCS and provides a detailed description of imaging and treatment options, particularly interventional management.

Transjugular approach for successful recanalization and stenting for inferior vena cava stenosis

Budd-Chiari syndrome is a rare disease characterized by obstruction of outflow in the hepatic vein and/or the inferior vena cava (IVC). Percutaneous transluminal angioplasty and stent placement is nowadays considered to be the first-line treatment for central venous disease because of its minimal-invasive approach. IVC reconstruction by surgical approach is not preferred due to increased morbidity and disappointing patency rates. We describe a case of a long-segment, thrombotic, chronic total occlusion of the IVC that was dilated and stented using a recanalization technique involving the use of Brokenborough septal puncture needle, Mullin dilator and Accura balloon from the jugular approach.

Tamoxifen-associated Budd-Chiari syndrome complicated by heparin-induced thrombocytopenia and thrombosis: a case report and literature review

We reported a rare case of Budd-Chiari syndrome (BCS) associated with tamoxifen use, which was later complicated by heparin-induced thrombocytopenia and thrombosis (HITT). The patient was a 44 year-old woman with a medical history of lobular carcinoma in situ, who had been on tamoxifen for 2 years, presented with abdominal pain and distention. Imaging studies followed by a liver biopsy confirmed the diagnosis of BCS. On extensive work-up, the patient was found to have an unclassified myeloproliferative disorder with positive JAK-2 V617 mutation. After discontinuing tamoxifen, the patient was started on intravenous heparin. However, later in the course, she developed HITT. Myeloproliferative disorder, in conjunction with tamoxifen, predisposed the patient to be highly thrombophilic resulting in BCS. HITT was found to be relatively common in BCS. Anticoagulation and blood count need to be carefully monitored, and the possibility of HITT emergence in these patients should always be kept in mind.

An update on the diagnosis and management of Budd-Chiari syndrome

Budd-Chiari syndrome is a rare disorder caused by hepatic venous outflow obstruction and resulting hepatic dysfunction. Despite a lack of prospective randomized trials, much progress has been made in its management over the last 20 years. The main goals of treatment are to ameliorate hepatic congestion and prevent further thrombosis. The selective use of anticoagulation, vascular stents, transjugular intrahepatic portosystemic stent-shunt and liver transplant has resulted in a significant increase in survival. The diagnosis, initial management and long-term follow-up of patients with Budd-Chiari syndrome is reviewed. The concept of individualization of treatment and a stepwise approach to invasive procedures is also discussed.

Budd-Chiari syndrome

OBJECTIVE

Budd-Chiari syndrome (BCS) is an uncommon condition characterized by obstruction of the hepatic venous outflow tract. Presentation may vary from a completely asymptomatic condition to fulminant liver failure. BCS is an example of postsinusoidal portal hypertension. The management can be divided into three main categories: medical, surgical, and endovascular. The purpose of this article is to present an overall perspective of the problem, diagnosis, and management.

CONCLUSION

BCS requires accurate, prompt diagnosis and aggressive therapy. Treatment will vary depending on the clinical presentation, cause, and anatomic location of the problem. Patients with BCS are probably best treated in tertiary care centers where liver transplantation is available.

Spectrum of imaging in Budd Chiari syndrome

Budd Chiari syndrome is an uncommon heterogeneous group of disorders which occur due to obstruction at any level from the hepatic venules to the junction of inferior vena cava and right atrium of heart which has significant morbidity and mortality. An early diagnosis of the disease is required for appropriate treatment. Due to the diffuse nature of the disease, normal biopsy findings do not exclude the disease. Proper clinical history and imaging are essential for definitive diagnosis. In this pictorial essay, we discuss the imaging spectrum of Budd Chiari syndrome.

Large Clones With PNH-Type Phenotype are Not Common in Patients Presenting With Intra-Abdominal Thrombosis—A Prospective Study

Intra-abdominal thrombosis is a complication of paroxysmal nocturnal hemoglobinuria (PNH). There is scarcity of data on cases presenting with thrombosis in whom PNH is the predisposing factor. We assessed the role of PNH defect in 81 patients with intra-abdominal thrombosis, 44 patients of Budd Chiari syndrome and 37 patients of extra hepatic venous obstruction. Flowcytometry with glycosylphosphatidyl inositol-anchored proteins (GPI-AP)-CD55, -CD59, and -CD16 was performed on all patients and controls to assess the prevalence of deficiencies and PNH-type phenotype clone size. Deficiencies of individual GPI-AP were seen in 17.3% cases versus 3.4% controls. This was due to CD55 deficiency on red blood cells and CD16 deficiency on the granulocytes. Deficiency of multiple GPI-APs was less frequent (3.7% cases). Data of this study indicate that the PNH defect as detected with CD55, CD59, and CD16 is not an important cause of intra-abdominal thrombosis in northwestern India.

Budd-Chiari syndrome revisited: 38 years' experience with surgical portal decompression

OBJECTIVE

Ten years ago, we reported our results with what remains as the largest clinical experience with surgical portal decompression for Budd-Chiari syndrome (BCS) in the West. Since then, our series has expanded to 77 patients, and there has been an explosion of interest in and publications about BCS. The objectives of this study are to assess the validity of our observations and conclusions regarding BCS reported 10 years ago by expansion of our series of patients and observations of outcomes over an additional decade of close follow-up.

METHODS

Seventy-seven patients with BCS were allocated to three groups: group I, 39 had hepatic vein occlusion alone, treated by side-to-side portacaval shunt (SSPCS); group II, 26 had inferior vena cava occlusion treated by mesoatrial shunt in eight and combined SSPCS and cavoatrial shunt (CAS) in 18; and group III, 12 had decompensated cirrhosis too late for portal decompression who were listed for liver transplantation (LT). An extensive diagnostic workup included angiography with pressure measurements and needle liver biopsy. Follow-up was 100%, lasting 5-38 years.

RESULTS

In group I, long-term survival is 95% with 36 free of ascites, leading lives of good quality 5-38 years post-SSPCS. In group II, mesoatrial shunt was discontinued after 1990 because of a high failure rate, but combined SSPCS-CAS has resulted in 100% survival for 5-25 years. In group III, six patients (50%) are alive and well for more than 5 years post-LT. Serial liver biopsies following portal decompression have shown long-term reversal of the lesions of BCS.

CONCLUSIONS

Long-term survival following portal decompression of BCS in the West has not been equaled by any other form of therapy, medical or surgical. It is imperative to perform surgical portal decompression early in the course of BCS in order to avoid irreversible liver damage.

Outcome of non surgical hepatic decompression procedures in Egyptian patients with Budd-Chiari

AIM: To evaluate outcome of patients with Budd-Chiari syndrome after balloon angioplasty ± stenting or transjugular intrahepatic portosystemic shunt (TIPS).

METHODS: Twenty five patients with Budd-Chiari syndrome admitted to Ain Shams University Hospitals, Tropical Medicine Department were included. Twelve patients (48%) with short segment occlusion were candidates for angioplasty; with stenting in ten cases and without stenting in two. Thirteen patients (52%) had Transjugular Intrahepatic Portosystemic Shunt. Patients were followed up for 12-32 mo.

RESULTS: Patency rate in patients who underwent angioplasty ± stenting was 83.3% at one year and at end of follow up. The need of revision was 41.6% with one year survival of 100%, dropped to 91.6% at end of follow up. In patients who had Transjugular Intrahepatic Portosystemic Shunt, patency rate was 92.3% at one year, dropped to 84.6% at end of follow up. The need of revision was 38.4% with one year and end of follow up survival of 100%. Patients with patent shunts showed marked improvement compared to those with occluded shunts.

CONCLUSION: Morbidity and mortality following angioplasty ± stenting and TIPS are low with satisfactory outcome. Proper patient selection and management of shunt dysfunction are crucial in improvement.

Portal vein thrombosis and budd-Chiari syndrome

Venous thrombosis results from the convergence of vessel wall injury and/or venous stasis, known as local triggering factors, and the occurrence of acquired and/or inherited thrombophilia, also known as systemic prothrombotic risk factors. Portal vein thrombosis (PVT) and Budd-Chiari syndrome (BCS) are caused by thrombosis and/or obstruction of the extrahepatic portal veins and the hepatic venous outflow tract, respectively. Several divergent prothrombotic disorders may underlie these distinct forms of large vessel thrombosis. While cirrhotic PVT is relatively common, especially in advanced liver disease, noncirrhotic and nontumoral PVT is rare and BCS is of intermediate incidence. In this article, we review pathogenic mechanisms and current concepts of patient management.

TIPS for Budd-Chiari syndrome: long-term results and prognostics factors in 124 patients

BACKGROUND & AIMS

Budd-Chiari syndrome (BCS) is a rare and life-threatening disorder secondary to hepatic venous outflow obstruction. Small series of BCS patients indicate that transjugular intrahepatic portosystemic shunt (TIPS) may be useful. However, the influence of TIPS on patient survival and factors that predict the outcome of TIPS in BCS patients remain unknown.

METHODS

One hundred twenty-four consecutive BCS patients treated with TIPS in 6 European centers between July 1993 and March 2006 were followed until death, orthotopic liver transplantation (OLT), or last clinical evaluation.

RESULTS

Prior to treatment with TIPS, BCS patients had a high Model of End Stage Liver Disease and high Rotterdam BCS prognostic index (98% of patients at intermediate or high risk) indicating severity of liver dysfunction. However, 1- and 5-year OLT-free survival were 88% and 78%, respectively. In the high-risk patients, 5-year OLT-free survival was much better than that estimated by the Rotterdam BCS index (71% vs 42%, respectively). In the whole population, bilirubin, age, and international normalized ratio for prothrombin time independently predicted 1-year OLT-free survival. A prognostic score with a good discriminative capacity (area under the curve, 0.86) was developed from these variables. Seven out of 8 patients with a score >7 died or underwent transplantation vs 5 out of 114 patients with a score <7.

CONCLUSIONS

Long-term outcome for patients with severe BCS treated with TIPS is excellent even in high-risk patients, suggesting that TIPS may improve survival. Furthermore, we identified a small subgroup of BCS patients with poor prognosis despite TIPS who might benefit from early OLT.
