The procedure of treating aortic aneurysms with stent-grafts is known as EVAR. This stands
for EndoVascular Aneurysm Repair. I most commonly use EVAR to treat aneurysms of the abdominal aorta, thoracic aorta and popliteal
artery. There are still a number of surgeons who perform open surgery for these conditions. In my opinion, open surgery should
be reserved only for those patients in whom EVAR is technically not possible. In my practice, more than 90% of patients are
suitable for EVAR. In the average UK hospital this figure is 40 to 60%.
