Mr Usman Jaffer explains that there are two options to repair an abdominal aortic aneurysm (AAA): endovascular repair (EVAR) and open repair. In terms of EVAR, this is done by keyhole incisions in the groin. A device (called a stent graft) is inserted into the femoral artery (artery in the thigh) in the groin and travels up the blood vessels to reach the aorta inside the abdomen (belly). It is fixed inside the aorta to strengthen it and prevent it from rupturing (bursting).
