Endovascular Aneurysm Repair (EVAR)

EVAR is a “keyhole” surgery technique where an abdominal aortic aneurysm (AAA) is repaired using a fabric covered stent.  A graft is sized to tailor fit the aneurysm by taking measurements on detailed CT scan images preoperatively. This operation can be carried out under regional (local) or general anaesthetic.

The technique involves making two small cuts in the groin to expose the arteries leading to the legs. Wires are threaded up the artery through access sheaths inserted through the femoral arteries in the groin. This is done under x-ray control into and above the aneurysm. A pre-measured stent graft is run over that wire into position. The stent graft is then deployed under X-ray vision in the manner of a ship being opened in a bottle. When the stent is finally deployed it seals the aneurysm from the blood flow.

After an initial period in the recovery unit where vital signs are closely monitored patients return to the ward. Resumption of normal diet and early mobilisation are expected. Most patients will be discharged home 2-3 days after surgery. Some patients may experience complications – your surgeon will discuss potential complications with you in advance of the procedure.
