Abstract：Objective To assess the clinical outcomes of brachiocephalic artery-sparing aortic arch repair combined with stent-graft elephant trunk technique for treatment of Stanford type A aortic dissection. Methods Twenty-three patients with Stanford type A aortic dissection requiring arch replacement underwent brachiocephalic artery-sparing aortic arch repair combined with stent-graft elephant trunk technique. The operations were performed within 72 h (20 cases) or 3-14 days (3 cases) after the onset of aortic dissection. Results There was no perioperative death in these cases. The mean extracorporeal circulation time was 209±52 min, the aortic cross clamp time was 85±21 min, and the mean chest tube output within the first 24 h after the operation was 570 ± 263 mL; none of the patients required chest reopening for management of bleeding. Postoperative acute renal failure requiring hemodialysis occurred in 3 cases, transient neurologic dysfunction in 2 cases, paraplegia in case and hematosepsis in 1 case. No such complications as permanent neurologic deficit or postoperative visceral malperfusion occurred in these cases. All the patients survived and were discharged from hospital without experiencing severe complications in the follow-up for 6-18 months. Conclusion Brachiocephalic artery-sparing aortic arch repair combined with stent-graft elephant trunk technique is a safe and simple procedure with controllable bleeding and can serve as an optional procedure for aortic arch replacement.
