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 arterystent occlusion and smooth blood in other visceral branches. No complications such as organ ischemia, lower limbischemia 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.
