One-stage replacement of the aorta from arch to thoracoabdominal region.

Abstract

We present our experience with one-stage replacement of thoracic aneurysm from the ascending aorta to the thoracoabdominal aorta. Fourteen patients (10 male and 4 female; mean age 53.6 ± 12.4 years) with extended thoracic aortic aneurysms underwent graft replacement. The pathology of the diseased aorta was chronic aortic dissection in 13 patients and intraoperative retrograde aortic dissection in 1 patient. Five patients had Marfan syndrome. In a previous operation, 1 patient had undergone the Bentall procedure, 4 had hemiarch replacement for acute type A dissection, and 1 had a Y-graft for abdominal aortic aneurysm. The approach to the aneurysm was posterolateral thoracotomy with rib-cross incision extended to the retroperitoneal abdominal aorta. Arterial inflow for cardiopulmonary bypass consisted of the femoral artery in 13 patients and abdominal aortic aneurysm graft in 2. Venous drainage site was the femoral vein in 7, femoral vein and pulmonary artery in 3, and pulmonary artery in 1. All patients had antegrade cerebral perfusion and visceral perfusion. Hospital mortality occurred in 1 patient due to acute myocardial infarction. Actuarial survival at 5 years after the operations was 96.5 ± 9.8%. Freedom from the subsequent aortic events was 91.0 ± 2.9% at 5 years. Our treatment method for extensive thoracic aneurysm, from the ascending aorta to the thoracoabdominal aorta, achieved satisfactory results via the use of specific strategies and appropriate organ protection according to the aneurysm extension in the selected patients.
