[Massive bleeding from the upper digestive tract in patients with pseudoaneurysm of splenic artery].

Pancreatic pseudocysts are common complication of both chronic and acute pancreatitis. Sanguination from damaged peripancreatic vessels into the lumen of pseudocyst results in pseudoaneurysm. The rupture of pancreatic pseudoaneurysm into the lumen of digestive tract causes massive bleeding witch source is often difficult to find during endoscopic examination. We present a case of patient with chronic alcohol pancreatitis, with pancreatic pseudocyst and of acute bleeding from upper digestive tract. In the endoscopy we found gastric ulcer with visible vessel. During hospitalization we observed increase the diameter of pseudocyst and circulation of it's liquid contence. Second-look endoscopy showed gastric fundic varices. Surgical operation revealed pseudoaneurysm of splenic artery inserting pressure on gastric wall.
