A change in the treatment of abdominal aortic aneurysms.

Objective: One of the most exciting potential applications of percutaneous therapy is the treatment of abdominal aneurysms.

Methods: Of 230 patients treated with a self-expanding polyester-lined stent-graft for different aortic pathologies at our institution, we selected 80 abdominal aneurysm cases undergoing treatment (from May 1997 to December 2002). The stent was introduced through the femoral artery, in the hemodynamic laboratory, with the patient under general anesthesia, with systemic heparinization, and induced hypotension.
