A Fatal Case of Hepatic Portal Venous Gas Associated With Hemodialysis.

Hepatic portal venous gas is a rare cause of acute abdomen caused by leakage of air from the gastrointestinal tract to the portal venous system. The mortality is high, particularly when associated with intestinal ischemia or necrosis. We describe a fatal case of hepatic portal venous gas and pneumatosis intestinalis due to hemodialysis-related hypotension and severe atherosclerotic disease.
