Abstract

The portal venous system comprises all of the veins draining the abdominal part of the digestive tract, and tributaries of the portal vein are the splenic, superior mesenteric, left and right gastric vein, paraumbilical and cystic veins. The portal vein could be occluded in various clinical settings that may cause portal venous system thrombosis. And rarely aneurysms of the portal venous system may be presented. Multiphasic contrast enhanced computed tomography is a useful tool for both perfusion abnormalities and morphologic analysis of the portal venous system and the liver and it enables discrimination between bland and neoplastic portal vein thrombi.
