Abdominal aortic aneurysm: a review of endoluminal treatment

Abdominal aortic aneurysm (AAA) carries a high mortality if left untreated. Until recently, most patients with AAA were treated with surgical repair. However, endoluminal graft treatment is rapidly becoming an alternative to surgical repair due to lower morbidity and comparable perioperative mortality rates. Despite this optimism patients and operators should keep in mind the palliative nature of these endovascular repairs and the lifelong need for surveillance, before embarking on these procedures. Endoleaks remain to be a significant problem leading to aneurysm expansion and occasionally rupture. Durability of the existing endograft devices remains to be seen. Careful patient selection is critical to success with these procedures. With future advancements in the endograft device technology, methods of patient surveillance, and patient care, there may be a shift from conventional surgical approaches to endovascular repair for the treatment of AAA.
