Mid- and long-term results of open repair for chronic type B aortic dissection in endovascular era

AbstractMedical management is the standard treatment of chronic type B aortic dissection (CTBAD). However, the roles of open surgical repair (OSR) and thoracic endovascular repair (TEVAR) in patients with CTBAD remain controversial. Thus, this study aimed to assess and compare the mid- and long-term clinical outcomes of OSR via left thoracotomy with that of TEVAR for CTBAD. The data of 85 consecutive patients who underwent surgery for CTBAD from April 2007 to May 2021 were retrospectively reviewed. The patients were divided into two groups: Group G, which included patients who underwent OSR, and Group E, which included patients who underwent TEVAR. Groups G and E comprised 33 and 52 patients, respectively. Preoperative and postoperative computed tomography (CT) studies were retrospectively analyzed for the maximum diameter. The mean duration of the follow-up period was 5.8  years. Operative mortality did not occur. There was no difference in complications, such as stroke (G: 2 vs. E: 0,p = 0.30), paraplegia (G: 1 vs. E: 1,p = 0.66), and respiratory failure (G: 2, vs. E: 0,p = 0.30). The difference in preoperative factors was observed, including the intervals between onset and operation (G; 4.9 years vs. E; 1.9 years,p <  0.01), maximum diameter in preoperative CT (G; 59.0 mm vs. E; 50.5 mm,p <  0.001), and maximum false lumen diameter (G; 35.5 mm vs. E; 29.0 mm,p <  0.01). There was no significant difference in the mid- and long-term su...
