My 2nd pinion

Hi went to see a Prof. Micheal Morgan in Sydney last week, He says that my AVM is operable as it falls in to category 3, where as Doctors at Monash said it is too risky to operate.
Lots of questions in my mind now, of what I should do, as much I am excited to hear a positive solution. How long the recovery be, Any body who has being treated by Prof Micheal In Sydney? Any experience with surgery or what I should expect to go through would help
