I'm not positive if it's the first but it's the first that I've heard of.  Moyamoya surgery (I believe EDAS type) was performed at JFK Medical center in Edison N.J.   

     The surgeon is Dr. Jonathan Brissman who came to JFK from Mass. General in Boston.  From what I've learned, he's published several articles on cerebral vascular disease with Dr. Chris Ogilvy also from Mass General and a known Moyamoya expert.
     When I find out more about Dr. Brissman, I'll post the info on our site.

Just thought I'd share what I consider good news.
