title: Endovascular stent-grafts for the repair of infrarenal abdominal aortic aneurysms: a brief review.
abstract: In the United States nearly 1.5 million people have abdominal aortic aneurysms (AAAs). The natural history of AAAs is to enlarge and rupture. Rupture of an AAA results in an estimated 15,000 deaths per year. The major objective in the treatment of AAAs is to prevent aneurysm rupture and death. Endoluminal grafting for the treatment of aortic aneurysms is the most exciting topic in vascular surgery today. It is anticipated that approximately half of all aneurysms in the infrarenal abdominal and descending thoracic aorta will be repaired endovascularly in the future. Despite the enthusiasm for this technology, there are unanswered questions like the long-term fate of the device, management of endoleaks, and the ability to protect the patient from subsequent rupture. This article describes the two FDA approved devices in clinical use today and the indications, techniques, and potential pitfalls of endoluminal stent-grafting for the treatment of AAAs.
