title: Gastroesophageal variceal bleeding caused by hepatoportal arteriovenous fistula.
abstract: Hepatoportal arteriovenous fistulas are usually traumatic in origin and may result in portal hypertension and serious complications. We report a 34-year-old female with a history of abdominal trauma, who developed symptoms of tarry stools and hematemesis 5 years later. Esophageal and gastric varices with bleeding were diagnosed by upper gastrointestinal endoscopy. Abdominal ultrasonography and computerized tomography favored noncirrhotic portal hypertension. An extrahepatic hepatoportal arteriovenous fistula was demonstrated by angiography. The patient underwent surgery to correct the condition. The liver had a smooth surface and both the common hepatic and gastroduodenal arteries were ligated during surgery. The postoperative course was uneventful. The varices later disappeared.
