Repair of an infected aortic aneurysm using an aortic allograft and a venous autograft: report of a case.

We describe the successful surgical treatment of an unusual type of infected aortic aneurysm. The aneurysm emerged around the distal part of the ascending aorta and the proximal part of the arch and involved the innominate artery. The infection was attributed to prolonged catheter placement in the right jugular vein for intravenous hyperalimentation several years earlier. We repaired the aneurysm using an aortic allograft and a venous autograft under antegrade selective cerebral perfusion with deep hypothermia. Pathological examination revealed a pseudoaneurysm. The patient recovered well and has shown no sign of recurrence of the infection.
