Abstract: Objective To explore the feasibility of 3D printing-assisted endovascular treatment of complex aortic disease. Methods Five patients with complex aortic disease admitted to the Department of Vascular Intervention, Zhongshan Hospital of Traditional Chinese Medicine from December 2019 to October 2021 were included. After preoperative CT angiography （CTA）, three-dimensional reconstruction of the aorta was performed, and a 1∶1 aortic model was printed on a 3D printer to assist in surgical strategy formulation and surgical simulation. Results One case of suprarenal abdominal aortic penetrating ulcer, one case of juxtarenal abdominal aortic pseudoaneurysm, two cases of thoracic aortic aneurysm involving the supra-arch branches, and one case of aortic dissection involving the supra-arc branches. 3D model of the aortic lesions was printed before the operation, and the surgical plans were made according to the results. Technical success rate was 100%, there was no endoleak,stent displacement,stent occlusion or loss of visceral artery branches. Conclusion 3D printing-assisted endovascular treatment can make the endovascular treatment of complex aortic diseases intuitive and precise, with good feasibility.
