ABSTRACT
The feasibility of endovascular repair of infrarenal abdominal aortic aneurysm (EVAR) was demonstrated over a decade ago by Parodi, Volodos and coworkers.1,2 The technology associated with EVAR has evolved at a rapid pace in parallel with recognition of the factors required for successful endovascular aneurysm exclusion. Enthusiasm for this technique has, however, been tempered by reports of significant device and non-device related complications. These complications have included aneurysm rupture, prevention of which is the basis of treatment.3 In fact, a cumulative risk of 1 per cent per year has been reported by the European collaborators on Stent-graft Techniques for abdominal aortic Aneurysm Repair (EUROSTAR) using first and second generation endovascular grafts.4
