Multicenter, Open-labeled, Single-arm Clinical Trial of Multi-Branch AOrtic Reconstruction of Complex Aortic Aneurysm With G-iliac System [BAO-G] Technique
Multi-Branch AOrtic Reconstruction With G-iliac System (BAO-G) Technique is a novel technique of endovascular repair of complex aortic aneurysm, which using off-the-shelf iliac branched devices to reconstruct the visceral branches. This study aims to verify the perioperative safety and 5-year efficacy of BAO-G technique in the endovascular treatment of complex aortic aneurysms through a prospective, multicenter, open-label, single-arm clinical trial, and to provide evidence for the selection of clinical procedures for complex aortic aneurysm patients in the future.
• Diagnosed with Crawford type III-IV thoracoabdominal aortic aneurysm or complex abdominal aortic aneurysm, with a healthy proximal landing zone (\>20mm length, angulation \<60°) in the descending aorta and maximum aneurysm diameter ≥4cm
• Scheduled for endovascular aortic repair with commercially available iliac branch devices for visceral artery reconstruction
• Signed informed consent and committed to protocol-defined follow-up
