Acute mycotic aneurysm of the ascending aorta following aortocoronary bypass: successful repair.
Acute mycotic aneurysms of the ascending aorta following aortocoronary bypass are exceedingly rare. To our knowledge, there have been few reports of successful management. The central location of this lesion places it apart from acute or chronic mycotic aneurysms in general and enhances its lethality. The availability of ascending and arch aortography, computerized chest tomography and the techniques of peripheral cardiopulmonary bypass, deep hypothermia and reversible circulatory arrest for prolonged periods of time permit successful management. The purpose of this report is to (1) illustrate such a problem; (2) describe its successful management; (3) review the etiology of mycotic aneurysms, historically and contemporarily; and (4) to differentiate early, acute mycotic aneurysms of the ascending aorta following aortocoronary bypass (usually lethal) from similar late chronic processes (readily reparable).
