Hi Koko,
I am in Ontario, and my surgeon in Toronto at first did not believe I needed surgery! He told me to go sky-diving!! I requested a new doctor, who performed the Gamma Knife surgery within a few months. Four years after routine MRIs they found two areas they had missed, and after another angiogram, they tried to treat them with “superglue” through another angiogram. That didn’t work because the vein hooked, so another MRI later, I went through the Gamma Knife again in 2012. I didn’t find there was much of a waiting for the surgeries–really just a lot of waiting to find out what needed to be done.
I had double vision and was told I would need surgery to correct it, but it healed itself within six months. I was ten at the time of my AVM bleed but am 20 now.
I wish you all the best!!
