RESUMO
Endovascular aneurysm repair involves the transluminal placement of a graft within the aneurysm that completely excludes the sac from the general circulation, the graft is anchored in place by a balloon-expandable or self-expanding metal frame that supports all or part of the graft and provides a watertight seal proximal and distal to the dilated segment of the artery. Because it avoids the need for laparotomy, cross-clamping of the aorta, and the obligatory blood loss associated with the opening of the aneurysm sac, this technique has much to be recommended. It has the potential to reduce the morbidity and mortality associated with conventional open abdominal aortic aneurysms [AAA] repair and extend the scope of repair to those patients with severe medical co-morbidities who were previously denied treatment
