The objective of this research was to investigate whether seasonal variations influence the outcomes of type B aortic dissection (TBAD) patients with thoracic endovascular aortic repair (TEVAR).
From 2003 to 2020, a retrospective cohort study was performed, which included 1,123 TBAD patients who received TEVAR. Medical records were used to gather data on baseline characteristics. Outcomes including all-cause mortality and aortic-related adverse events (ARAEs) were tracked and analyzed.
Of the 1,123 TBAD patients in this study, 308 received TEVAR in spring (27.4%), 240 cases in summer (21.4%), 260 cases in autumn (23.2%), and 315 cases in winter (28.0%). Patients in the autumn group had a significantly lower risk of 1-year mortality than those in the spring group (hazard ratio: 2.66, 95% confidence interval: 1.06-6.67, = 0.037). Kaplan-Meier curves revealed that patients who underwent TEVAR in autumn had a lower risk of 30-day ARAEs ( = 0.049) and 1-year mortality ( = 0.03) than those in spring.
This study confirmed that TEVAR operated in autumn for TBAD was associated with a lower risk of 30-day ARAEs and 1-year mortality than in spring.
本研究的目的是调查季节变化是否会影响接受胸主动脉腔内修复术（TEVAR）的B型主动脉夹层（TBAD）患者的治疗结果。
对2003年至2020年期间进行的一项回顾性队列研究进行分析，该研究纳入了1123例接受TEVAR治疗的TBAD患者。通过病历收集患者基线特征数据。对包括全因死亡率和主动脉相关不良事件（ARAEs）在内的治疗结果进行跟踪和分析。
本研究中的1123例TBAD患者中，308例在春季接受TEVAR治疗（27.4%），240例在夏季接受治疗（21.4%），260例在秋季接受治疗（23.2%），315例在冬季接受治疗（28.0%）。秋季组患者的1年死亡率风险显著低于春季组（风险比：2.66，95%置信区间：1.06 - 6.67，P = 0.037）。Kaplan-Meier曲线显示，秋季接受TEVAR治疗的患者30天ARAEs风险（P = 0.049）和1年死亡率风险（P = 0.03）均低于春季患者。
本研究证实，与春季相比，秋季对TBAD患者进行TEVAR手术，30天ARAEs风险和1年死亡率风险更低。
