Evaluation of Clinical Efficacy and Safety of Aortal Stent-graft Modelled Printing 3D Model Printing Technology - Multicenter, Randomized Clinical Trial
the comparison of physician-modified stent-graft created in 3D models versus custom-made devices in the treatment of complex abdominal aortic aneurysm
⁃ Female and male subjects age ≥ 18 2. Subject need to meet one of the following criteria:

• Subjects with juxtarenal or suprarenal abdominal aortic aneurysm, type IV thoraco-abdominal aneurysm with aneurysm growth rate ≥ 0.5cm during 6 months
• Type IA endoleak of post-implantation of abdominal stent- graft 3. Iliac arteries morphology with aortic stent graft implantation to be restored 4. Aortic segment which is proximal to aneurysm
• Length ≥20mm
• Diameter 20mm-36mm
• Aortic suprarenal angle ≤75 degrees 5. Survival \> 2 years
