目的：本研究旨在探讨50岁以下急性A型主动脉夹层（AAAD）患者的特点和手术结果。方法：回顾性评估2007年1月至2017年6月在我院连续接受手术治疗的307例AAAD患者。将患者分为两组：年轻组（50岁以下患者31例）和老年组（50岁以下患者276例）结果：两组的院内死亡率相似（3.2% vs. 9.4%，p=0.19）。年轻组的 5 年总生存率高于老年组（97% vs. 71%，p=0.017）。在 5 年时无主动脉相关死亡和远端主动脉再次手术方面没有观察到显着差异（97% vs. 87%，p=0.26；86% vs. 92%，p=0.093）。年轻患者术后降主动脉假腔未闭的比例明显高于老年患者（76% vs. 30%，p
Objectives: The aim of this study is to investigate the characteristics and surgical outcomes of acute type A aortic dissection (AAAD) in patients younger than 50 years of age.Methods: We retrospectively evaluated 307 patients who consecutively underwent surgical treatment for AAAD in our institute from January 2007 to June 2017. Patients were classified into two groups: the young group with 31 patients aged younger than 50 and the old group with 276 patients aged 50 years or older.Results: In-hospital mortality was similar in both groups (3.2% vs. 9.4%, p=0.19). Overall survival at 5 years was higher in the young group than that in the old group (97% vs. 71%, p=0.017). No significant differences were observed in freedom from aorta-related death and distal aortic reoperation at 5 years (97% vs. 87%, p=0.26; 86% vs. 92%, p=0.093). The percentage of young patients with postoperative patent false lumen at the descending aorta was significantly higher than that of old patients (76% vs. 30%, p
