Portal Vein Thrombosis

Acute Portal Vein Thrombosis can occur in patients with abdominal inflammation or prothrombotic disorder.  Chronic Portal Vein Thrombosis is more likely related to cirrhosis.

Symptoms are: abdominal pain, splenomegaly, fever, ascites, hematemesis and weight loss.  Acute thrombosis is associated with pain and fever, while chronic thrombosis more commonly presents with esophageal varices and bleeding.

Treatment is anticoagulation for acute portal vein thrombosis.  Thrombolysis may be considered.
The treatment for chronic portal vein thrombosis involves treating the associated cirrhosis and ascites and may involve porto-systemic shunting (surgical or TIPS).
