Endovascular aneurysm repair with unibody bifurcated stent grafts
Objective: To evaluate the efficacy of using unibody bifurcated stent grafts in endovascular aneurysm repair. Methods: The clinical data of 15 patients with abdominal aortic aneurysm, 5 patients with iliac aortic aneurysm and 5 patients with abdominal aortic or iliac aortic dissection undergoing endovascular aneurysm repair with unibody bifurcated stent grafts (Shanghai MicroPort Medical Co., Ltd.) were retrospectively analysed. Results: The surgical success rate was 100% (25/25) with an overage operative time of 42.4 min. No type I or type III endoleak occurred, iliac thrombosis occurred in one case after operation and on death occurred during perioperative period. Follow-up was conducted for 3 to 16 months and no type II endoleak was noted during review visits. Conclusion: Endovascular aneurysm repair using unibody bifurcated stent graft is a preferable choice of the treatment options for abdominal aortic aneurysm or dissecting aneurysm. However, the long term results still need to be verified.
