Liver Cirrhosis, Portal Vein Thrombosis
Conditions
Brief summary
Portal vein thrombosis (PVT) is prevalent among patients with cirrhosis, and its prevalence rises with the severity of liver disease. Numerous studies have indicated that patients developing PVT experience elevated portal pressure and associated complications, such as increased incidence of variceal bleeding, higher rates of failed variceal bleed control, rebleeding, and short-term mortality. Additionally, the development of PVT adversely affects post-transplant outcomes, correlating with increased 30-day mortality among transplant recipients with PVT. Current guidelines lack clarity regarding the optimal choice of anticoagulation therapy for patients with cirrhosis. This study aims to evaluate the efficacy and safety of enoxaparin and dabigatran in achieving complete recanalization of portal vein thrombosis in cirrhotic patients over a 6-month period.
