- Abstract: Objective To analyze the risk factors of occurrence of complications after fenestrated or branched endovascular aortic repair(F/B-EVAR)for complex thoracoabdominal aortic diseases.Meth-ods Clinical materials of 147 patients with F/B-EVAR for thoracoabdominal aortic diseases in the Department of Vascular Surgery of Drum Tower Hospital Affiliated to Medical College of Nanjing Uni-versity from 2021 to 2023 were retrospectively analyzed.Multivariate correlation analysis was used to explore the risk factors for postoperative complications during the mid-term follow-up.Results There were 13 postoperative deaths,with a mortality rate of 8.8％;52 patients experienced overall surgery-related complications,with an incidence rate of 35.4％;31 patients had postoperative endoleaks,with an endoleak rate of 21.1％;14 patients had branch stent-related endoleaks,involving 14 bran-ches;and 4 patients had branch occlusion,involving 5 branches.The re-intervention rate in this study was 20.4％(30/147),with 20 cases(13.6％)of postoperative renal insufficiency and 1 case of postoperative paraplegia due to spinal cord ischemia,as well as 1 case of postoperative stent infec-tion.Risk factor analysis for postoperative mortality,overall complications,endoleaks,and postoper-ative renal failure was conducted,and the risk factors for overall complications included preoperative renal insufficiency,aortic disease,aortic tortuosity angle＞60 °,and average number of branch re-constructions.The independent influencing factors for postoperative endoleaks included gender,age,history of renal insufficiency,history of thoracic endovascular aortic repair(TEVAR),aortic tortuosity angle＞60°,and true lumen diameter in thoracoabdominal aortic dissection(TAAD).The inde-pendent influencing factor for postoperative renal failure was preoperative renal insufficiency.Con-clusion Female,age,thoracoabdominal aortic aneurysm(TAAA),history of renal insufficiency,history of TEVAR,aortic tortuosity angle＞60°,and true lumen diameter in TAAD are the influen-cing factors for postoperative complications in patients with thoracoabdominal aortic diseases,and the possible related factors are TAAA sac diameter and TAAD false lumen diameter.
