Gastric varices may also be found in patients with thrombosis of the splenic vein, into which the short gastric veins that drain the fundus of the stomach flow. The latter may be a complication of acute pancreatitis , pancreatic cancer , or other abdominal tumours, as well as hepatitis C .
The splenic vein can be affected by 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. These include varices in the stomach wall due to hypertension in the short gastric veins and abdominal pain. This results in gastric varices ...
Esophageal varices are due to a connection between the left gastric vein and the azygos-hemiazygos veins; gastroesophageal varices are due to connections between either the anterior branch of the left gastric vein and esophageal veins or the short gastric & posterior gastric vein and esophageal veins.

Patients with portal hypertensive gastropathy may experience bleeding from the stomach, which may uncommonly manifest itself in vomiting blood or melena; however, portal hypertension may cause several other more common sources of upper gastrointestinal bleeding, such as esophageal varices and gastric varices. On endoscopic evaluation of the ...
The inferior mesenteric vein connects in the majority of people on the splenic vein, but in some people, it is known to connect on the portal vein or the superior mesenteric vein. Roughly, the portal venous system corresponds to areas supplied by the celiac trunk , the superior mesenteric artery , and the inferior mesenteric artery .
In human anatomy, the superior mesenteric vein (SMV) is a blood vessel that drains blood from the small intestine (jejunum and ileum). Behind the neck of the pancreas , the superior mesenteric vein combines with the splenic vein to form the portal vein that carries blood to the liver .
The short gastric veins, four or five in number, drain the fundus and left part of the greater curvature of the stomach, and pass between the two layers of the gastrolienal ligament to end in the splenic vein or in one of its large tributaries.
Splenic vein thrombosis is a rare condition that causes esophageal varices without a raised portal pressure. Splenectomy can cure the variceal bleeding due to splenic vein thrombosis. [citation needed] Varices can also form in other areas of the body, including the stomach (gastric varices), duodenum (duodenal varices), and rectum (rectal ...
