Role of Computed tomography in predicting prognosis of Hepatic portal venous gas.

Background: The aim of this study was to report through 13 cases the particularities of abdominal computed tomography (CT) aspects of hepatic portal venous gas (HPVG) and its correlation with patient prognosis.

Methods: We analyzed abundance of HPVG and its association with pneumatosis intestinalis (PI) in correlation with fatal outcome using chi-square tests.

Results: Etiologies were mesenteric infarction (n=5), sigmoid diverticulitis (n= 1), septic shock (n=1), postoperative peritonitis (n=1), acute pancreatitis (n=1), iatrogenic cause (n=3) and idiopathic after a laparotomy (n=1).
