Abdominal aortic aneurysm following acute pancreatitis.

Vascular lesions may complicate the course of acute pancreatitis. The activated pancreatic enzymes, particularly elastase, might cause lysis of the elastic component of the arterial wall thus leading to aneurysmal changes. This report is on a case of aneurysm of the infrarenal aorta following complicated acute pancreatitis and treated by endovascular technique.
