PURPOSE: To evaluate the significance of transcatheter arterial embolization(TAE) of pseudoaneurysmcomplicating pancreatitis. MATERIALS AND METHODS: This study was based on a retrospective analysis of eightcases, in which TAE for the control of pseudoaneurysm complicating pancreatitis was attempted. All patients weremales, and were aged between 35 and 65(mean, 47) years. Seven had a history of episodes of chronic pancreatitisand one case was the result of acute pancreatitis. All patients underwent diagnostic angiography andsuperselective embolization. RESULTS: Arteries in which pseudoaneurysm had occurred were the gastroduodenal(n=5), inferior pancreaticoduodenal (n=1), superior mesenteric artery root (n=1), and the celiac axis (n=1). Sixcases were treated successfully without complications, but in two, embolization failed due to a wide aneurysmalneck arising from the superior mesenteric artery root and celiac axis. In four successful cases, pseudoaneurysmswere completely resolved within three to six months of embolization. One of the other two remained as apseudocyst, while in the other, also a pseudocyst, surgery was performed. CONCLUSION: Because TAE in patientswith pseudoaneurysm complicating pancreatitis has a high success rate, and also leads to absolute resorption of apseudocyst, TAE is the preferred pre-surgical treatment mode.
