Karron, I had Gamma knife November 10th, 2016. I went in early in the morning, and had the “halo” mounted, for this I sat on a bed, they did some local anesthetic at the screw sites and bolted in on. It was tender but not too bad. I then went for a CT scan and then MRI, these didn’t take long as they were very focussed as I had many scans previously. I didn’t need an angio that day as I had two previously, one on May 13th, that was day two in the hospital when my AVM bled and then one August 3rd. The MRI was only 20 minutes, my previous one was over an hour, really loud with the frame mounted. I had a bit f a wait and the actual gamma knife procedure took 24 minutes, plus a little time to get situated. It was quiet, music playing and actually quite relaxing as I was glad to be on with it. Once done, they immediately removed the frame, and the pressure was gone. I was home that afternoon by 1:30 pm. This was a Thursday and I was back to work on Monday. I have never heard of the immediate 50% reduction in bleed possibility, but these are all different, I know it reduces as time passes.
If the staff at your facility is like mine here, they are incredible, I was really relaxed and treated great. I was happy to be there, be treated and get the clock started. I’m now just over 6 months out and go for a follow up MRI at the one year mark. I have had some head aches lately, but nothing concerning and could be due to a little bit of swelling, nothing I need medication for as of yet.
My choice was gamma due to significantly less risk associated to the craniotomy, due to location, fairly deep and a strong possibility of my sight being effected. If you have any questions I may be able to help with, feel free to fire away. I’ll answer then as best I can based on what I experienced. Take Care, John
