Abstract:
Objective To compare the differences in clinical prognosis and safety between thoracic endovascular aortic repair(TEVAR)combined with bare metal stent(BMS)implantation therapy and TEVAR alone in patients with type B aortic dissection(TBAD)after 6 months.Methods The clinical and imaging data of patients diagnosed with TBAD and treated with TEVAR or TEVAR combined with BMS implantation in Nanyang Central Hospital from March 2023 to March 2024 were retrospectively collected.The patients were divided into TEVAR group and TEVAR+BMS group according to different treatment methods.The aortic remodeling indicators and postoperative complications at discharge and 6 months after surgery were compared between the two groups.Results A total of 37 patients were included,including 20 patients in the TEVAR group and 17 patients in the TEVAR+BMS group.There were no statistically significant differences in baseline data between the two groups(all P＞0.05);at discharge and 6 months after surgery,the true lumen diameters and true lumen ratios of the abdominal aorta(proximal level of the celiac trunk and proximal level of the left renal artery)in the TEVAR+BMS group were better than those in the TEVAR group(all P＜0.05);the degree of thrombosis of the false lumen at 6 months after surgery was better in the TEVAR+BMS group than in the TEVAR group(P＜0.05);there was no statistically significant difference in postoperative complications between the two groups(P＞0.05).Conclusions TEVAR combined with BMS implantation therapy can significantly improve the aortic remodeling effect of patients with TBAD,without increasing the risk of postoperative complications and death caused by aortic-related factors.Bare stent implantation as an auxiliary treatment method for endovascular repair is a safe and effective optimized treatment plan.
