Repair of the symptomatic aberrant aortic arch aneurysm without hypothermic circulatory arrest.

Manifestation of anomalies of the aortic arch in adulthood has been reported in the literature. The symptoms stem from the compression of the trachea and esophagus or peripheral arterial ischemia associated with coarctation of the aberrant arch. The aberrant arch aneurysms are subject to complications of rupture or dissection. This may be the first reported case of a large complex aneurysm of an anomalous aortic arch resected on cardiopulmonary bypass without any period of hypothermic circulatory arrest or distal ischemia.
