摘要
Objectives: This study was designed to review the ascending aortic diameter of patients undergoing surgery for AAD in China and its influence on prognosis. Methods: In the period between January 2018 and January 2020, 265 patients eligible for analysis of ascending aorta were included in this study. The maximum diameter of the ascending aorta was assessed using preoperative computed tomography (CT) scan for patients. Results: The mean diameter of the ascending aorta of the reference population was 48.16 +/- 9.37 mm, and the percentage of subjects with an aorta <55 mm was 80.38%. In this study, we found that BMI, hypertension, and bicuspid aortic valve are the main factors affecting the widening of the ascending aorta, and the diameter of the ascending aorta in patients with AAD is negatively correlated with the patient's long-term prognosis. However, there is no significant difference in survival rates among patients with different ascending aortic diameter. Conclusions: Ascending aortas with smaller diameter are also prone to dissection, most of which occur at a lower surgical threshold than recommended by current guidelines. Therefore, the diameter of ascending aorta cannot be used as an independent risk factor for high-risk patients with aortic dissection, but it can be used as an important indicator to evaluate the long-term prognosis of patients.
