Objective To study the application of 3D printing technology in multi-center fenestrated/branched endovascular repair(F/B-EVAR)for endovascular repair of abdominal aortic diseases.Methods From Feb 2018 to Mar 2023,The clinical and followup data of 316 cases of abdominal aortic lesions undergoing repair with F/B-EVAR at 69 medical centers nationwide using 3D printing technology to guide physician-modified stent graft were retrospectively analyzed.Results The mean follow-up time of the patients was 23 months(2-60 months),and 24 cases were lost to follow up,the follow-up rate was 92.4％(292/316),the mean postoperative hospitalization time was(8.2±4.9)days.A total of 944 main abdominal branch arteries were reconstructed.Intraoperative reconstruction of 11 branches failed,with a success rate of 98.8％(933/944).Within 30 days after surgery,8 patients died(2.5％),and 6 patients died during follow-up,a total of 14 patients died(4.4％).There were 11 cases(3.5％)of spinal cord ischemia and no patient suffered from permanent paraplegia.There were 19 patients(6.0％)with postoperative renal function injury.Internal leakage was found in 26 patients,and the rate of internal leakage was 8.2％.Conclusion 3D printing technology can accurately locate the location of branch arteries,simplifing the surgical process,shortening the learning curve,and improving clinical efficacy.
