Recovery from stents depends on what type of stent is placed and what procedure is used. The recovery is usually rapid from12 to 24 hours when the stent is placed by angioplasty which is minimally invasive. In the case of stent grafts into the aorta, the recovery time is often longer because the procedure of placing the stent to repair the aorta is more complex, and so it may take several weeks to completely recover, unless the less invasive endovascular stent grafting procedure is done. This is a newer method of treating an abdominal aortic aneurysm and also involves threading the graft through an artery using a catheter.
