Abstract:
Objective:To evaluate the efficacy of new arch-clamping technique in Sun’s procedure to repair acute type A aortic dissection.Methods:67 consecutive patients with acute type A aortic dissection who underwent total arch replacement and frozen elephant trunk implantation(TAR+ FET) from Dec 2019 to Dec 2022 with using new arch-clamping technique during operation. Relative intraoperative and postoperative variables and complications were compared.Results:Cardiopulmonary bypass time was(166.66±32.81)min, the aortic occlusion time was(100.49±19.96)min, the circulatory arrest time was(3.97±1.63)min, the lowest nasopharyngeal temperature was(25.716±1.304)℃, and the lowest bladder temperature was(26.209±1.552)℃. The whole group died in hospital in 2 cases(2.98%), cerebral infarction in 3 cases(4.48%), transient neurological dysfunction in 4 cases(5.97%), paraplegia patients in 1 case(1.49%), renal failure requiring continuous dialysis in 4 cases(5.97%).Conclusion:New arch-clamping technique decrease postoperative complication, and is a safe and feasible innovative approach to effectively improve surgical outcome of Sun’s procedure for repair of acute type A aortic dissection.
