A 46-year-old male and a 53-year-old female each required a second surgery because of dilatation of the distalaortic arch (> 55 mm) approximately 5 years after ascending replacement for acute type A dissection. Bothpatients showed patent false lumen associated with endoleakage from the distal anastomosis. We performed distalarch to descending aorta replacement through a left thoracotomy using femorofemoral cardiopulmonary bypasswith a 50% assist rate. The dissecting flaps were excised from both the proximal and distal aortic stumps, and polyester grafts were anastomosed in a double-barrel fashion under the aortic cross-clamps. No changes in the aorticarch diameters were observed 1 year after surgery. Here, we report the efficacy of proximal double-barrel anastomosis for residual dissecting aneurysm caused by endoleakage from distal anastomosis after emergency repair fortype A dissection.
