[A case of hepatic portal venous gas caused by transient type ischemic enteritis].

We report a case of hepatic portal venous gas (HPVG) caused by transient type ischemic enteritis. The patient was a 65-year-old woman, previously given a diagnosis of hypertension and diabetes mellitus. She was admitted to our hospital because of vomiting and epigastric pain. Abdominal computed tomography showed dilatation of the stomach and small intestine, with hepatic portal and superior mesenteric venous gas. Upper gastrointestinal endoscopy showed diffuse edematous and erosive change, and an extensive ulcer in the duodenum. There was no muscular defence, and physical and laboratory examinations did not indicate necrotic bowel. We diagnosed as HPVG caused by ischemic enteritis, and she responded to conservative treatment. We discuss a rare case of HPVG caused by transient type ischemic enteritis with references.
