Critique

Isolated gastric varices can be a complication of splenic vein thrombosis. The splenic vein courses superior to the pancreas from the splenic hilum to the main portal vein. Recurrent (or severe acute) inflammation of the pancreas can lead to splenic vein thrombosis, which can cause gastric varices due to backup of blood flow into the short gastric veins. The incidence of gastric varices in those with splenic vein thrombosis ranges from 15% to 55%.

Diagnosis can be made with a CT of the abdomen with contrast, and definitive treatment is splenectomy. Bleeding from a splenic artery pseudoaneurysm can also occur after pancreatitis (hemosuccus pancreaticus), and causes hemodynanically significant bleeding into the peritoneum or the bowel lumen via the pancreatic duct. However, it does not result in gastric varices.
