Objective: To explore the clinical value of the treatment of aortic aneurysms with endovascular stent-graft prostheses.

Methods: Six patients were included in the study. 4 patients with infrorenal abdominal aneurysms involving the aortic bifurcation and the common iliac arteries received bifurcated stent-grafts; 1 patient with descending and abdominal aortic aneurysm received straight stent-graft; and 1 patient with right common iliac artery aneurysm received straight stent-graft. After a unilateral surgical arteriotomy, the endoprostheses were advanced through the femoral arteries and placed under the guidance of fluoroscope. CT and MRI were perfomed during the follow-up of 2-16 months.

Results: All patients got a primary success. The aortic aneurysms were completely excluded from the circulation. Two cases had a prolonged fever; 1 case was found a leakage 3 months later.

Conclusions: Our results suggest that endovascular treatment of aortic aneurysm is technically feasible and it can effectively exclude aortic aneurysms from the circulation. With further refinement, endoluminal repair may emerge as an interventional strategy to treat infrarenal aortic aneurysm, especially for patients at high surgical risk.
