Recurrent hepatic portal venous gas in a patient with hemodialysis- dependent chronic renal failure.

We report a case of recurrent hepatic portal venous gas (HPVG). A 51-year-old woman who had been undergoing hemodialysis for 19 years was admitted with abdominal pain. Computed tomography (CT) scans revealed the presence of HPVG, and bowel necrosis was confirmed at operation. After 1 year, the abdominal pain recurred. CT scans on the second admission also revealed HPVG; however, an exploratory laparotomy was negative. Recurring presentation of HPVG in the same patient has not been described previously.
