Background

Portal vein thrombosis (PVT) is a vascular disease of the liver that occurs when a blood clot occurs in the hepatic portal vein, leading to increased pressure in the portal vein system and reduced blood supply to the liver.

Inciting Causes

Clinical Features

Acute

  • Upper abdominal pain developing suddenly or progressing over a few days
  • Possibly accompanied by nausea, hepatomegaly, splenomegaly; may be accompanied by persistent non-spiking fever in the setting of systemic inflammation
  • Other signs/symptoms based on underlying cause (e.g. bleeding disorders, hepatic stigmata if due to cirrhosis)

Chronic

  • May be clinically silent in a portion of patients and diagnosed incidentally during a CT exam for other reasons (e.g. acute pancreatitis)
  • Associated with portal hypertension

Differential Diagnosis

Evaluation

  • Typically diagnosed on abdominal CT with contrast

Management

Disposition
