An Ex-Situ Arterial Reconstruction for the Treatment of an Infected Suprarenal Abdominal Aortic Aneurysm Involving Visceral Vessels

A 66-year-old man, who had complaints of back pain, high fever, and constipation, with a suprarenal infected abdominal aortic aneurysm involving visceral vessels, was successfully treated by an ex situ arterial reconstruction. Blood culture revealed bacteroides melaninogenicus. After establishing a temporary bypass from right axillar to right external iliac artery, both renal arteries-superior mesenteric artery and common hepatic artery-were preliminary bypassed from external iliac arteries. Then aortic trunk reconstruction was performed with the body twisting left side to separate the graft from the infected field. The patient had good recovery and no evidence of recurrent infection 31 months after the operation.
