A case of portomesenteric venous gas detected on computed tomography.

Portomesenteric vein gas is a rare condition, which pathogenesis is not completly understood. One of causes is e.g. mesenteric ischemia. Pathogenesis of this condition are: intraabdominal sepsis, interventional procedures, liver transplantation, Crohn disease and trauma. In 15% of causes its idiopathic. Hepatic portal venous gas predict high risk of mortality (>50%). An advanced radiology techniques such as computed tomography can be helpful in recognizing of this pathology stage.
