Background: This study was performed to demonstrate the feasibility and effectiveness of a novel off-the-shelf endograft (G-Branch™; Lifetech Scientific, Shenzhen, China) for the treatment of patients with complex thoracoabdominal/abdominal aortic aneurysms.
Methods: Three patients (1 with a suprarenal abdominal aortic aneurysm and 2 with thoracoabdominal aortic aneurysms) were treated with the G-Branch endograft involving 2 proximal inner branches for the celiac axis and superior mesenteric artery and 2 distal side directional branches for the bilateral renal arteries.
Results: Technical success was achieved in all 3 patients, and no postoperative complications occurred. At 6-month follow-up, no adverse events occurred, and all the target vessels were patent.
Conclusions: The newly developed G-Branch device allows the achievement of total endovascular revascularization of the visceral and renal arteries. Use of this device is feasible and effective. Long-term follow-up and a larger clinical trial are necessary to evaluate its reliability and durability.
