My mom was advised to undergo MVD with the only risk that it might not work for her since she had 5 prior destructive surgeries or possible hearing loss or spinal fluid leak. Well, this has been a nightmare. They think that the movement of the artery caused plaque to dislocate and caused a stroke. We're on day 8 in ICU and it looks like she has quite a long haul ahead. We asked a lot of questions before the surgery and were totally taken aback by this -- Beware.
