title: Extraanatomic aortic bypass for repair of aortic coarctation.
abstract: We describe two adult patients who underwent extraanatomic ascending aorta-to-descending thoracic aorta bypass grafting for repair of aortic coarctation through a median sternotomy and posterior pericardial approach. Of the two patients, one presented with coarctation and concurrent cardiovascular disorders, and the other, with residual coarctation. Cardiopulmonary bypass was established with double arterial cannulation in the aorta or axillary artery and the femoral artery ensure adequate perfusion proximal and distal to coarctation and bicaval cannulation. The heart was retracted cephalic and superiorly, and the descending thoracic aorta was exposed through the posterior pericardium. After achieving distal anastomosis, the graft was directed anterior to the inferior vena cava and lateral to the right atrium, and anastomosed to the right lateral aspect of the ascending aorta. A 14-mm graft was used. In one patient receiving concomitant procedures, mitral valve repair and replacement of the ascending aorta was performed after the distal anastomosis.
