Endovascular Aortic Aneurysm Repair

Endovascular Aortic Aneurysm Repair (EVAR) is a procedure used for the treatment of the aneurysms of the aorta. The aorta is the largest blood vessel in the body which takes blood from the heart to supply the rest of the body. An aneurysm of the aorta is a potentially fatal condition in which the walls of the aorta have become weakened resulting in an enlargement of its diameter in the affected segment of the aorta. If left untreated the aorta may rupture.

In EVAR, a cylindrical tube composed of a special fabric supported by a metal mesh called a stent graft is placed into the aorta under X-ray guidance. The stent graft is carefully positioned and anchored so as to seal tightly to the aorta at points both above and below the aneurysm, so that the blood passes through the graft rather than the affected area of the aorta. Since blood is prevented from getting to the weakened walls of the aneurysmal artery, this reduces the further bulging of the aorta and hence the risk of rupture. This procedure is not for all aortic aneurysms since it is not without risks and the interventional doctor will be able to carefully guide and advise as to whether it is appropriate for a given case. Advanced Cardiovascular Institute was the first to do this procedure in Trinidad and is arguably the most experienced centre for aortic aneurysm stenting in the Southern Caribbean.
