Liver cirrhosis caused by chronic Budd-Chiari syndrome

Rare Case of Budd-Chiari Syndrome in a Young Child: A Diagnostic Conundrum

Budd-Chiari syndrome (BCS) is an uncommon vascular disorder in which venous thrombosis prevents the venous outflow of the liver. The obstruction is primarily at the level of hepatic veins and inferior vena cava. Here, we present a case of a two-and-a-half-year-old male child who presented with complaints of abdominal distension for two months and fever and watery diarrhea for one month. Physical examination showed the patient was anemic with palmar erythema. He was started on an empirical treatment of cefotaxime, metronidazole, and amikacin. Sensitivity and culture reports for blood and urine samples were negative, but abdominal computed tomography (CT) scan showed characteristic findings for BCS with caudate lobe hypertrophy. After the symptomatic treatment of the patient, a liver transplant was suggested as a last resort.

Epidemiological Characteristics and Etiology of Budd-Chiari Syndrome in Upper Egypt

Background and Objectives

Budd-Chiari syndrome (BCS) is a rare disorder caused by obstruction to hepatic venous outflow. It affects all races, usually during the third or fourth decade of life. Higher prevalence had being evident in developing countries. The aim of the present study was to clarify sociodemographic features, clinical, radiological presentations, and etiology of BCS among Upper Egyptian patients.

Patients and Methods

This retrospective cohort study enrolled 50 Upper Egyptian Patients with confirmed primary BCS. Liver, coagulation, and thrombophilia workup profiles were performed as anticardiolipin antibodies, lupus anticoagulant, protein C, protein S, and antithrombin III assays. Factor V Leiden and JAK2 mutations were assessed. Full radiological assessment was done.

Results

Fifty patients were included. There were 28 males (56%) and 22 females (44%) with mean age (32.5 ± 11.1 years). The etiological factor was not identified in 22% of cases (n=11). Isolated factor C deficiency was found in 26% (n=13) with male predominance 39.3% and protein S deficiency in 10% (n=5). Factor V Leiden mutation was the etiology in 5 patients (10%). Membranous web and antiphospholipid syndrome each were the etiology in 8% (n=4). Behςet’s disease was diagnosed in 4% (n=2). Cases of liver cirrhosis(LC) were 41/50(82%)they were :33/50(66%) LC child class C, 8 /50(16%)  LC child class B, and 0/50 (0%) LC child class A. Abdominal pain was the most common symptom (96%), and ascites was the most common sign (82%). Obstruction of hepatic veins was present in 80%.

Conclusion

BCS in Upper Egyptian patients was mainly occurred in males in the third and fourth decade of life, mostly with liver cirrhosis. The most common etiology is isolated protein C deficiency followed by Factor V Leiden mutation and isolated protein S deficiency. Hepatic veins obstruction was the most common pattern of vascular involvement.

Budd-Chiari Syndrome: An Uncommon Cause of Chronic Liver Disease that Cannot Be Missed

Budd-Chiari syndrome (BCS), or hepatic venous outflow obstruction, is a rare cause of liver disease that should not be missed. Variable clinical presentation among patients with BCS necessitates a high index of suspicion to avoid missing this life-threatening diagnosis. BCS is characterized as primary or secondary, depending on etiology of venous obstruction. Most patients with primary BCS have several contributing risk factors leading to a prothrombotic state. A multidisciplinary stepwise approach is integral in treating BCS. Lifelong anticoagulation is recommended. Long-term monitoring of patients for development of cirrhosis, complications of portal hypertension, hepatocellular carcinoma, and progression of underlying diseases is important.

Pseudocirrhosis in Chronic Budd Chiari Syndrome With Janus Tyrosine Kinase 2 (JAK2) Mutation

Budd-Chiari syndrome (BCS) occurs when there is hepatic venous outflow obstruction. Chronic BCS may result in liver cirrhosis due to long-standing obstruction and tend to present late. We present the first case of BCS secondary to Janus tyrosine kinase 2 (JAK2) mutation resulting in "pseudocirrhosis" rather than cirrhosis of the liver. Pseudocirrhosis clinically and radiologically mimics cirrhosis without the classical histopathological changes, and it is usually associated with metastatic cancers.

Review article: a multidisciplinary approach to the diagnosis and management of Budd-Chiari syndrome

BACKGROUND

Budd-Chiari syndrome (BCS) is a rare but fatal disease caused by obstruction in the hepatic venous outflow tract.

AIM

To provide an update of the pathophysiology, aetiology, diagnosis, management and follow-up of BCS.

METHODS

Analysis of recent literature by using Medline, PubMed and EMBASE databases.

RESULTS

Primary BCS is usually caused by thrombosis and is further classified into "classical BCS" type where obstruction occurs within the hepatic vein and "hepatic vena cava BCS" which involves thrombosis of the intra/suprahepatic portion of the inferior vena cava (IVC). BCS patients often have a combination of prothrombotic risk factors. Aetiology and presentation differ between Western and certain Asian countries. Myeloproliferative neoplasms are present in 35%-50% of European patients and are usually associated with the JAK2-V617F mutation. Clinical presentation is diverse and BCS should be excluded in any patient with acute or chronic liver disease. Non-invasive imaging (Doppler ultrasound, computed tomography, or magnetic resonance imaging) usually provides the diagnosis. Liver biopsy should be obtained if small vessel BCS is suspected. Stepwise management strategy includes anticoagulation, treatment of identified prothrombotic risk factors, percutaneous revascularisation and transjugular intrahepatic portosystemic stent shunt to re-establish hepatic venous drainage, and liver transplantation in unresponsive patients. This strategy provides a 5-year survival rate of nearly 90%. Long-term outcome is influenced by any underlying haematological condition and development of hepatocellular carcinoma.

CONCLUSIONS

With the advent of newer treatment strategies and improved understanding of BCS, outcomes in this rare disease have improved over the last three decades. An underlying haematological disorder can be the major determinant of outcome.
