I was my neurosurgeons first Moya Moya patient, if I had know that before surgery I would have went somewhere else. Was done 11-26-12 at St. Louis University Hospital. Second stroke in 6-2013 had second right sided surgery on 11-12-13 by Dr. Steinberg at Stanford, 6 month post testing showed I still have blood flowing to my brain, instead of pre-surgery neg. flow.
