1Department of Surgery, Erasmus University Hospital Dijkzigt, Rotterdam, The Netherlands.
Insights
Budd-Chiari syndrome involves hepatic venous outflow obstruction, leading to portal hypertension. Treatment often requires surgery, including shunting or caval obstruction removal, with liver transplantation as a last resort.
Area of Science:
- Medicine
- Hepatology
- Vascular Surgery
Background:
- Budd-Chiari syndrome encompasses various hepatic venous outflow obstructions.
- These obstructions cause clinical symptoms of portal hypertension and hepatomegaly.
- Obstructions occur at three distinct levels, each with unique etiologies.
Purpose of the Study:
- To provide a comprehensive overview of Budd-Chiari syndrome.
- To discuss the different etiologies and clinical presentations.
- To outline current and potential treatment strategies.
Main Methods:
- Review of existing literature on hepatic venous outflow obstruction.
- Analysis of different obstruction levels and their associated causes.
- Evaluation of surgical and non-surgical treatment modalities.
Main Results:
- Budd-Chiari syndrome presents with varied clinical manifestations, from mild to end-stage liver disease.
- Surgical interventions, such as caval obstruction removal and shunting procedures, are primary treatments.
- Hepatic transplantation is a life-saving option for patients with end-stage liver failure.
Conclusions:
- Budd-Chiari syndrome necessitates diverse treatment approaches based on obstruction level and patient condition.
- Surgical management is crucial for most patients.
- Liver transplantation offers a definitive solution for advanced cases.
Abstract:
Budd-Chiari syndrome is the generic term for different forms of hepatic venous outflow obstruction resulting in a clinical picture of portal hypertension and hepatomegaly. Three levels of venous outflow obstruction may be recognized, affecting respectively the small intrahepatic (IVC). Each level of obstruction is related to a different aetiology. Clinical manifestations range from mild symptoms to acute or chronic end-stage liver disease. Treatment is surgical in the great majority of patients. Occlusion of the IVC may be treated by removal of the caval obstruction in selected patients. Hepatic outflow obstruction may be circumvented by different forms of shunting from the portal or upper mesenteric vein to the IVC or right atrium, depending on the level of obstruction and the difference in venous pressure. For the rare patient presenting with acute or chronic end-stage liver failure, hepatic transplantation may be a life-saving procedure.
