Epidemiology, Diagnosis, and Treatment of Portal Vein Thrombosis

In recent years, the incidence of portal vein thrombosis (PVT) in patients with cirrhosis has increased; ranges from asymptomatic partial to complete occlusion. Treatment is difficult. Anticoagulation therapy may be optimal first-line treatment for acute PVT who lack variceal bleeding or mesenteric ischemia. Minimally invasive options include mechanical thrombectomy, chemical thrombolysis, and stent placement. However, effectiveness timing anticoagulation interventional therapies remain unclear.
