ABSTRACT

Objective:To investigate the imaging characteristics of uncomplicated acute type B aortic dissection (uATBAD) and the short-term and mid-term outcomes treated with thoracic endovascular aortic repair (TEVAR).Methods:One hundred and forty uATBAD patients treated by TEVAR at Zhejiang Provincial People's Hospital from Jan 2015 to Aug 2021 were retrospectively analyzed. Patients were divided into non-high-risk characteristics group (uATBAD group, 22 cases) and high-risk characteristics group (high-risk uATBAD group, 118 cases) according to the presence or absence of high-risk characteristics. The clinical and follow-up data were analyzed, and the incidence of complications, re-intervention rate, and mortality in the perioperative period and 5-year follow-up were evaluated.Results:The aortic diameter, false lumen diameter and the proportion of laceration in lesser curvature in the high-risk group were higher than those in the non-high-risk group ( P<0.05). There was no significant difference in the incidence of perioperative complications and 30 day mortality between two groups ( P>0.05). The follow-up time ranged from 6 to 83 months (mean 38.3 months). The 5-year mid-term follow-up showed that there was no significant difference in the incidence of aorta-related complications, re-intervention rate, and mortality between two groups ( P>0.05). Conclusions:The imaging characteristics of different typing uATBAD were significantly different. The short- and mid-term clinical effects of TEVAR were similar between the two groups.
