Endovascular Abdominal Aortic Aneurysm Repair

Printer-friendly versionSend by emailPDF version

Endovascular Aneurysm Repair (EVAR) is a newer method of repairing aortic aneurysms without cutting into the abdomen. It uses a synthetic fabric tube mounted onto stents which are introduced into the inside of the artery through small incisions in each groin. In comparison to traditional open repair, the recovery time is usually quicker and shorter.

Not all aneurysms, however, are suitable for this type of repair and in those situations open repair is recommended. Furthermore, even if endovascular repair is possible, it carries specific risks such as damage to the arteries to the legs as the graft is introduced, or movement of the stent graft over time causing what is termed an "endoleak".

Because it is a newer technique it does not have the same track-record as open AAA repair, and so the performance of these repairs over the long term is still being studied. Nevertheless, it is a popular and very suitable means of treatment of many patients.
