make an appointment with a Neurosurgeon..preferably one skilled in vascular. There are a few options available....one, watch it, two, surgery, three, radiation (bad thing with radiation, it takes about 2-3 years for results) and four embolization (much like an angiogram but they put glue in it to seal it). The 'team' will guide you on which option is best for you. sometimes it is a combination of the options...good luck to you
My cousin's husband had 2 AVM's. They were causing him to pass out and have bad headaches. He had the surgery done in NY by a doctor known for this procedure. It went really well but when in there they saw another one. He had radiation for it the 1st time but it didn't work that well so he had the surgery. He is doing really well now. Good luck!
