OBJECTIVE: Our aims were to describe a new surgical technique for the treatment of type A aortic dissection (TAAD) and to report the operative outcomes of 154 patients. SUMMARY BACKGROUND DATA: Surgical treatment of TAAD is complicated and carries a high mortality risk. To lower this risk, we developed a simplified procedure in which a stent graft was implanted as frozen elephant trunk (FET), and the proximally trimmed vascular graft was sutured from the inside of the aortic arch using the inclusion technique under moderate hypothermic circulatory arrest and antegrade selective cerebral perfusion. METHODS: We conducted a retrospective analysis of 154 cases of TAAD treated with our novel technique (93 men and 61 women, 52.5 ±â€Š11.4 years). Computed tomography angiography was performed before discharge and at 6 months postoperatively. RESULTS: In-hospital mortality rate was 5.19%, with paraplegia occurring in 2 patients (1.3%) and stroke in 6 (3.9%). The rate of closure of the aortic arch false lumen was 77.8%, with a 69.2% rate of descending thoracic aorta thrombosis at discharge. The survival rate was 91.1% at a mean follow-up of 21 ±â€Š10 months, with rates of aortic arch false lumen closure of 92.4% and descending thoracic aorta thrombosis of 74.3% at 6 months postoperatively. CONCLUSIONS: The aortic arch inclusion technique with FET provides a safe alternative for TAAD treatment, with satisfactory operative results. Short-term follow-up results are encouraging, and long-term outcomes need further evaluation.
