title: Percutaneous treatment of infrarenal aortic aneurysm with a polytetrafluoroethylene-covered nitinol stent-graft via a 10-F introducer sheath.
abstract: Two patients with dissecting (n = 1) and saccular (n = 1) aneurysms of the infrarenal abdominal aorta with very narrow proximal and distal aortic necks underwent treatment with percutaneous implantation of self-expandable polytetrafluoroethylene (PTFE)-covered nitinol stent-grafts on an off-label basis. The stent-grafts had maximum diameters of 13.5 mm and were deployed via 10-F introducer sheaths. Complete coverage of both aneurysms was achieved without evidence of endoleaks. The only complication observed was a pseudoaneurysm of the femoral access site in one patient, which was treated conservatively. Based on the experience described in this report, an aortic aneurysm with a narrow aortic neck can be safely treated with a PTFE-covered nitinol stent-graft.
