    Abstract:
    OBJECTIVE: To sum up the experience of performing ascending aorta replacement combined triple-branched stent graft implantation for acute Stanford type A aortic dissection. METHODS: From January 2010 to December 2010, 14 patients with acute Stanford type A aortic dissection underwent the procedure of performing ascending aorta replacement combined triple-branched stent graft implantation. Right axillary artery cannulation was used for cardiopulmonary bypass and selected cerebral perfusion. When the body temperature drops below 18°C, the ascending aorta was transected near the base of the innominate artery. From the incision, the triple-branched stent graft was implanted into the true lumen of the arch, descending aorta and the aorta bifurcation vessel. The transected stump of the ascending aorta was anastomosis to the proximal of the branched blood vessel prosthesis. RESULTS: Cardiopulmonary bypass time was (186 ± 38) min, cross clamp time was (101 ± 27) min, and average selective cerebral perfusion and lower body arrest time was (39 ± 11) min. The in-hospital mortality was zero. One patient of transient postoperative neurologic dysfunction, one of acute renal failure, one of transient limbs disturbance, one of secondary thoracotomy operation, one of gastrointestinal hemorrhage and one of postoperative chylothorax were observed. CT angiography rechecked showed the position of the vascular stent were satisfactory and the blood flow of arterial branches stents were lucid. The false lumen of the aortic arch and descending aorta closed with thrombus or shrinked. CONCLUSIONS: The patients required aortic arch to be reconstructed which had no main tearing of intima in the arch may be best candidates for this technique. Open triple-branched stent graft placement combined ascending aorta replacement is an effective means for aortic arch reconstruction in acute Stanford type A aortic dissection.
