To the Editor: The report of the short-term outcomes of the Open Versus Endovascular Repair (OVER) trial by Dr Lederle and colleagues1 provided little information regarding the endovascular procedures used for repair of abdominal aortic aneurysm (AAA). Although the open surgical procedure may have become standardized during the last 3 decades, with homogenous results regardless of the manufactured graft type, the same is not likely with the endovascular stent grafts.
