I am in the exact same boat.
My decision is difficult because no matter what I do there is a risk of loosing peripheral vision.
Did you decide what to do already? I see your post is over 2 months old. My doctor told me, my AVM is 3.4CM, Gamma Knife is not going to work. Period.
No ifs or buts, he said, Period.
Right now I am just trying to see which doctor is good for embolization.
Also, Gamma Knife takes 1-2 maybe even 3 or more years.
Some doctors said just do Gamma Knife becuase of ARUBA trial.
Quite frustrating considering that trial was only 229 people.
And it started 17 years ago.
And the trial never said Gamma Knife is safer than Embolization + Gamma Knife.
But it is difficult when doctors expect you (the patient) to decide.
When I have zero experience whatsoever in medical decisions.
The one doctor that was more adamant is the one that did surgery on my sister (she too had an AVM)
10 years later she is walking and talking.
So I tend to respect that doctor’s opinon.
The idea is when you reduce the flow to the nidus, you reduce the immediate risk.
When you do Gamma Knife with a 20% smaller nidus, then Gamma Knife is possible.
So in theory, this seems like it works.
The interventional radiologist told me since there is not a lot of data he wants me to think and think and think again if embolization is really what I want to do.
That Dr is making me nervous.
He did mention embolization is more common before surgery.
