Mr Bicknell explains that endovascular repair (keyhole surgery) is one of the main treatment options for abdominal aortic aneurysms (AAA). It involves a medical device called a stent graft. A small cut is made into the groin, and the stent graft is then fed up under X-ray guidance into the aorta. The main advantage over open repair is that there is less trauma, less complications shortly after the operation, and patients can usually go home within a day or two. But, in the long term, there can be leakage around the stent graft into the aneurysm (endoleak), which means there is a higher chance of having further procedures. This also means that you will need more regular follow up.
