Evolution and surgical management of a Mycobacterium avium complex aortic infection

Abstract

We present a case describing the successful surgical management of both an infected aneurysm and an aortic graft infection in a patient with disseminated Mycobacterium avium complex infection and AIDS. The patient was a 53-year-old man presenting with a ruptured type V thoracoabdominal aortic aneurysm and an isolated 7.1-cm infrarenal abdominal aortic aneurysm. He underwent emergent repair of his ruptured thoracoabdominal aneurysm using a rifampin-impregnated Dacron graft. This was followed by a temporizing endovascular aortic repair and was eventually bridged with an in situ repair using a cryopreserved cadaveric aortic homograft.
