Hello! I recently had open brain surgery (craniotomy) at Mayo to treat a 2nd fistula that couldn’t be safely reached by embolization. At day 23 I am pain free! No headaches, pressure or nausea!! It was a rough 22 days after surgery-lots of Tylenol and icing my head. It was discovered during surgery that I have a 3rd lesion that will probably need gamma knife radiation. It’s been a real rollercoaster ride the last 11 months, but I have total faith in my Mayo Clinic neurosurgeon in Rochester.
