Splenic Artery Pseudoaneurysm Rupture into a Pancreatic Pseudocyst with its Subsequent Perforation as the Cause of a Massive Intra-Abdominal Bleeding - Case Report.

Pseudocysts account for approximately 70% of all cystic lesions of the pancreas. One of the most dangerous complications of pancreatic pseudocysts is bleeding into the cystic lumen; the most common cause of the bleeding is a splenic artery pseudoaneurysm rupture. This paper presents the case of a 37-year-old man treated surgically for a massive intra-abdominal haemorrhage caused by a splenic artery pseudoaneurysm rupture into the lumen of a tail of pancreas pseudocyst with its subsequent perforation into the abdominal cavity and retroperitoneal space. Peripheral resection of the pancreas together with the cyst and spleen resection was performed. There were no postoperative complications.
