Endovascular AAA repair (EVAR), also known as endoluminal aortic stenting, is a minimally-invasive key hole technique for repairing abdominal aortic aneurysms. It is often a shorter procedure with a fast recovery and only a night or two in hospital. While the minimally invasive nature of it is appealing, it does come with a higher risk (when compared to open surgery) of requiring additional operations or procedures in the future to ensure the stent is secure and doesn’t move, kink or block. This is why after having an EVAR patients usually undergo regular monitoring of the stent by having a scan at least once a year to ensure there are no impending problems. Unfortunately not everyone with a AAA is able to have an EVAR. The aneurysm has to have certain characteristics in order to be treatable with endoluminal stenting. The shape of the aneurysm, the distance between the aneurysm and the kidney arteries, the size and shape of the iliac arteries are all key determining factors that influence the suitability of an aneurysm to be treated with an aortic stent.
