ABSTRACT
Objective:To evaluate the mid-term results of fenestrated/branched endovascular aortic repair (f/b EVAR) for the treatment of thoracoabdominal aortic aneurysms. M ethods The clinical data of 105 thoracoabdominal aortic aneurysm patients treated with f/b EVAR at the Department of Vascular Surgery of Nanjing Drum Tower Hospital from 2018 to 2019 were retrospectively analyzed. Results:There were 43 cases of thoracoabdominal aortic aneurysm and 62 cases of thoracoabdominal aortic aissection.A total of 336 branch arteries were reconstructed,and technical success rate was 94.3%. 100 cases (95.2%) were followed-up, 6 cases (5.7%) received reoperation interventions, and 11 cases (10.5%) died. During the follow-up period, 69 cases had complete imaging data. Based on the recent CT date of the thoracoabdominal aorta, 58 patients hael positive aortic remodeling and 11 patients hael negative and indeterminate remodeling; there were 31 cases (29.5%) of endoleaks, including 7 cases (6.7%) of type Ⅰb endoleaks, 8 cases (7.6%) of type Ⅱ, 1 case (0.95%) of type Ⅲa, 13 cases (12.4%) of type Ⅲc endoleaks and 2 cases (1.9%) of type Ⅳ. Conclusions:The mid-term follow-up results were satisfactory for TAAA treated with f/b EVAR. Internal leakage remains key point for f/b EVAR.
