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.
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.
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.
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.
本研究旨在展示一种新型即市分支型腹主动脉覆膜支架（G-Branch™；深圳乐普科生物技术股份有限公司）治疗复杂胸腹主动脉/腹主动脉瘤的可行性和有效性。
3 名患者（1 例肾上腹主动脉瘤和 2 例胸腹主动脉瘤）采用 G-Branch 覆膜支架治疗，该支架包含 2 个近端内脏分支用于内脏动脉（腹腔干和肠系膜上动脉），2 个远端分支用于双侧肾动脉。
所有 3 名患者均获得技术成功，无术后并发症。6 个月随访时，未发生不良事件，所有靶血管均通畅。
新开发的 G-Branch 装置可实现内脏动脉和肾动脉的完全腔内血管重建。该装置的使用是可行且有效的。需要进行长期随访和更大规模的临床试验来评估其可靠性和耐久性。
