Abstract:
Objective:To evaluate the safety and efficacy of 3D printing-assisted pre-fenestration and branch stent endovascular repair (F/b EVAR) in the treatment of thoracoabdominal aortic aneurysms.Methods:The clinical data of 26 patients treated with 3D printing-assisted F/b EVAR for complicated thoracic and abdominal aortic diseases at the Department of Vascular Surgery, the Ninth People's Hospital,Shanghai Jiaotong University School of Medicine from May 2019 to Sep 2022 were retrospectively analyzed.Results:The success rate in these 26 cases of TAAA with 3D printing combined with F/b EVAR was 97.89%, and the mean follow-up time was (8.03±4.15) months. Four cases had Ⅲc internal leakage and disappeared during the follow-up. One case of type Ⅲ leakage were narrowed during follow-up. Ic type internal leakage occurred in 1 patient and disappeared after the addition of a stent at the distal end. During the follow-up period, aortic CTA indicated that 1 patient had renal artery stent occlusion and smooth blood in other visceral branches. No complications such as organ ischemia, lower limb ischemia and all-cause death occurred during follow-up.Conclusion:3D printing-assisted F/b EVAR minimally invasive repair of TAAA is a feasible, effective and safe technique, with high success rate and low complication rate of visceral branch artery reconstruction.
