Ascending-to-Descending Aortic Bypass via Posterior Pericardium for Complex Coarctation of Aorta

Abstract

We introduce our surgical experience in treating recurrent aortic coarctation or coarctation associated with intracardiac abnormalities, which is difficult to manage. Four patients underwent the operation with hypothermic cardiopulmonary bypass. During the surgery, the posterior pericardium was opened and the thoracic aorta was dissected and sidebiting clamped, and an end-to-side anastomosis of the artificial graft to the descending aorta was performed. The graft was passed in between the inferior vena cava and the inferior right pulmonary vein and posterior to the pericardium. After that, the aorta was clamped and intracardiac repair was finished. Then the proximal artificial graft was anastomosed to the right side of the ascending aorta with heart beating. All patients recovered smoothly. There was no early or late death, without bleeding or other complications after operation. "Complex coarctation" can be treated with ascending-to-descending aortic bypass via posterior pericardium and satisfied result can be achieved.
