title: Hepatic portal venous gas associated with nonocclusive mesenteric ischemia in a hemodialysis patient.
abstract: Hepatic portal venous gas (HPVG) has been rarely described in chronic hemodialysis patients. We report a case of HPVG in a 59-year-old female patient with hemodialysis-dependent chronic renal failure due to diabetes who presented with acute onset of abdominal pain. Abdominal CT demonstrated the presence of gas in the portal veins. However, on laparotomy, no evidence of bowel necrosis or perforation could be found. HPVG seemed to be caused by nonocclusive mesenteric ischemia (NOMI), an increasingly recognized complication in hemodialysis patients. The patient responded favorably to intravenous hyperalimentation and antibiotics.
