Abstract:
Objective:To investigate the early and mid-term outcomes of aortic endovascular remodeling device (AERD) for Stanford type A aortic dissection (TAAD) in type Ⅱhybrid surgery, and to evaluate its clinical efficacy.Methods:46 patients with TAAD, including 14 females and 32 males, participated in the single-center clinical trial of West China Hospital of Sichuan University and underwent type II hybrid surgery (Bentall / ascending aorta replacement + AERD implantation) from February 2021 to October 2023. The safety and efficacy of AERD in type Ⅱ hybrid surgery for TAAD were estimated by clinical indicators (postoperative mortality, cardiovascular and cerebrovascular accidents, paraplegia, ischemia), and blood flow condition (volume of the true and false lumen, and suprachial branches).Results:Three patients (6.52%) died during the follow-up period, and the operation-related mortality was 4.35% (2/46). The remaining 43 patients were followed up for an average of (25.53±9.60) months. There were two cases (4.35%) of stroke after the operation, and paraplegia, acute renal insufficiency, and other severe complications were not noticed. The blood flow of the superior branch of the aortic arch was unobstructed, and there was no significant difference in the blood flow of the branch before the operation and at each follow-up time point. Compared to the pre-operation, the true lumen volume of the stent part increased by 59.0% and the false lumen volume decreased by 82.4%.Conclusion:AERD is a safe and effective alternative in type II hybrid surgery for acute TAAD, which is helpful in improving perioperative and short- and long-term survival rates and clinical outcomes.
