The splenic vein is subject to vein thrombosis, presenting some of the characteristics of portal vein thrombosis and portal hypertension, but localized to part of the territory drained by the splenic vein.

Venous drainage usually mirrors colonic arterial supply, with the inferior mesenteric vein draining into the splenic vein, and the superior mesenteric vein joining the splenic vein to form the hepatic portal vein that then enters the liver.

It collects branches from the stomach and pancreas, and most notably from the large intestine ( also drained by the superior mesenteric vein ) via the inferior mesenteric vein, which drains in the splenic vein shortly before the origin of the hepatic portal vein.

In contrast to the drainage of midgut and hindgut structures by the superior mesenteric vein and inferior mesenteric vein respectively, venous return from the coeliac artery is through either the splenic vein emptying into the hepatic portal vein or via smaller tributaries of the portal venous system.

Secondly, patients with acute pancreatitis may present with gastric varices as a complication of a fundus of the stomach drain into the splenic vein, thrombosis of the splenic vein will result in increased pressure and engorgement of the short veins, leading to varices in the fundus of the stomach.

Along the inferior aspect of the right lobe it projects exophytically from the hepatic surface . It extends up to the hepatic capsule as well . The arterial phase demonstrates evidence of mild tortuosity of right hepatic artery . Marginal dilatation is also seen of the same vessel . Lobular surface of the liver is observed, especially of the right lobe . There is evidence of thrombosis of the right portal vein . The thrombosis extends into the proximal portion of the left portal vein as well . partial thromobosis of the main portal vein is also seen . The superior mesentric vein is normal, the splenic vein is also normal . In the segment IV of the lever there is a subtle 1.0 to 1.4 cm hypoattenuated lesion, which is best appreciated in the portal venous phase and in the delayed phase . In arterial phase of the evalution, this lesion is marginally hypoattenuated to hepatic parenchyma . The caudate lobe is normal.
