Abstract:
Objective:To summarize the clinical experience and effect of applying 3D printing assisted with the technology of extracorporeal pre-fenestration in the treatment of thoracic/abdominal aortic aneurysm.Methods:From August 2019 to November 2020, 15 patients with thoracic/abdominal aneurysm involving visceral arteries were admitted to our center, including 11 males and 4 females, with mean age of 57-82(68.26 ±4.73) years old. According to diameters of visceral artery, thoracic aorta, abdominal aorta, and bilateral iliac arteries measured by CTA, we selected suitable stents and made a 3D printing model by professional software to guide the position of intraoperative external fenestration and the fenestration diameter to implement full cavity repair.Results:All operations were completed and one case was converted to laparotomy. The average time of operations was(200.67±41.00)min and hospital stay was(13.47±4.16)days without any death, organ failure, endoleak, paraplegia, graft infection and other complications.Conclusion:The application of 3D printing assisted with the technology of extracorporeal pre-fenestration in the treatment of thoracic/abdominal aortic aneurysm is feasible and effective, and the short-term results are satisfactory.
