Techniques used for repair of infra-renal AAA.¹⁶ (a) Open repair. Once inflow and outflow are controlled the aneurysm sac is opened and a synthetic graft is sutured in place onto normal aorta. (b) EVAR. A covered stent graft is inserted into the AAA via the common femoral arteries and is anchored to the normal aorta above the aneurysm and in the iliac arteries below, either by radial force from the spring mounted fabric, or supra-renal fixating hooks. Newer generation stent grafts have also been introduced that use aortic sealing technology. AAA, abdominal aortic aneurysm; EVAR, endovascular aneurysm repair.
