I had Mayo repair my aneurysm in 2016. Great experience in terms of care in the hospital. Would always go there for this complex surgery. After care which was not much except for seeing if you are healing is done by your local doctor. Rehab is set up by Mayo but done near your home. Went back to Mayo at their request after 2-3 months. Since then, I go once a year and usually only for one day. Tests and seeing the doctor are done the same day if there are no problems. Would highly recommend Mayo.
