Most abdominal aortic aneurysms are now treated using the Endovascular Abdominal Aortic Aneurysm Reconstruction technique or EVAR. This involves threading a large stent covered with a cloth like material through the arteries in the groin. The stent graft is opened on the inside of the aneurysm relining the aorta and relieving the pressure on the weakened and bulging aortic wall. Most patients who undergo EVAR are ready for discharge from the hospital in one to two days. Some aneurysms cannot be safely repaired using this technique and will require a conventional repair through an incision on the abdominal wall.
Many descending thoracic aortic aneurysms are now reconstructed using these same stent graft techniques. Others require incisions through the chest and abdominal cavities.
