We present two cases of patients with coincidental pancreatic disease and abdominal aortic aneurysm. Initial pancreaticoduodenectomy was followed by staged abdominal aortic aneurysm repair via a retroperitoneal approach in both cases. We recommend the retroperitoneal approach over the transperitoneal approach as an easier and safer method of aortic aneurysmorrhaphy after the Whipple procedure.
