[Splenic pseudoaneurysms following acute pancreatitis].

Splenic artery pseudoaneurysms are the most common of visceral artery pseudoaneurysms. Splenic pseudoaneurysms appear to have developed as a consequence of inflammatory processes adjacent to the splenic artery, particularly acute pancreatitis and chronic pancreatitis with associated pseudocysts. They are often asymptomatic and picked up on abdominal examination for ultrasound or CT scanning for other conditions. Complications include rupture with retroperitoneal hemorrhage or intraperitoneal hemorrhage. Two cases of splenic pseudoaneurysms, following acute pancreatitis, are reported between the years 1987 and 1996.
