The recovery time for most patients following surgery to repair an abdominal aortic aneurysm is two to three months, MedlinePlus reports. If the aneurysm is repaired before it ruptures, the prognosis typically improves.
A patient can expect a hospital stay of about five to 10 days following surgery, according to MedlinePlus. The first stop in the hospital is usually an intensive care unit for monitoring, and the patient is sometimes fitted with a breathing machine during the first 24 hours. The patient is also typically given a urinary catheter and tubing through the nose and stomach to assist in draining and feeding for a day or two. Blood-thinning medication and an epidural pain treatment are also administered while the patient slowly regains normal functions and movements.
