During your procedure, you’ll have anesthesia, so you won’t feel any pain. Your surgeon will make a small incision near the aneurysm. If you have a thoracic aortic aneurysm, you’ll have an incision in your chest. For an abdominal aortic aneurysm, you’ll have an incision in your abdomen. Your surgeon will then remove the weakened section of your artery and replace it with a graft made from a synthetic material, such as Dacron®.
If your aneurysm is small, your surgeon may thread a catheter through a vein near your groin to reach the affected area and place an endovascular stent graft – a small tube with metal mesh to support it – in the artery wall to reinforce it instead of removing the weakened piece.
In most cases, your surgery will take 3 to 6 hours.
