Portal vein thrombosis is a form of venous thrombosis affecting the hepatic portal vein, which can lead to portal hypertension and reduction in the blood supply to the liver.

Signs and symptoms[edit]

Causes[edit]

Causes can include pancreatitis, cirrhosis, diverticulitis, and cholangiocarcinoma. It is also a known complication of splenectomy.[1]

Diagnosis[edit]

The diagnosis of portal vein thrombosis is usually made by ultrasound, computed tomography with contrast or magnetic resonance imaging. D-dimer levels in the blood may be elevated as a result of fibrin degradation.

Treatment[edit]
