Endovascular Aortic Aneurysm Repair (EVAR) is a procedure done by an interventional cardiologist, used to repair a widened area of the aorta, called aneurysm. An aneurysm occurs due to weakness in the wall of the artery. When used to treat thoracic aortic disease, the procedure is specifically termed TEVAR (Thoracic Endovascular Aortic Aneurysm Repair).
How Is It Done?
In the EVAR procedure, a stent graft is inserted into the aneurysm through small incisions in the groin, without surgically opening or removing part of the aorta, thereby offering an alternative treatment choice to open surgery. The stent is placed within the patient’s vasculature, thereby excluding the aneurysmal sac from blood flow and preventing the walls of the aneurysm from rupturing.
Not every patient or every aneurysm is suitable for EVAR. In particular, aneurysms arising close to or above the kidneys are more difficult to treat in this way. You will be assessed with a scan to determine if your aneurysm can be treated by endovascular repair. If suitable you will be offered a choice of type of repair by your surgeon. If this cannot be undertaken at your local hospital, you may need to travel to a centre that can perform endovascular repair.
