Abstract

The management of an acute type A aortic dissection in the setting of peripheral vascular malperfusion is not well defined. Several institutions proceed with initial percutaneous intervention to restore end organ perfusion, followed by delayed operative repair of the type A dissection. This strategy is associated with high mortality rates from aortic rupture, myocardial infarction, and stroke. We describe a technique, where acute limb ischemia is concomitantly managed with the replacement of the ascending aorta/hemiarch or aortic arch. In addition to axillary artery cannulation, the ischemic lower extremity is perfused through a polytetrafluoroethylene (PTFE) graft, which is connected to the cardiopulmonary bypass (CPB) circuit. doi: 10.1111/jocs.12376(J Card Surg 2014;29:526–528)
