Spinal AVM's - Cyberknife London

I met with my consultant oncologist today in Harley Street, London where we agreed to proceed with the cyberknife treatment of my remaining 2 AVM's at L1 and L3. The AVM at L5 was embolised in january this year.
It seems things are moving quickly now in the private sector as it looks like I'll get another spinal angiogram next week in order to map out the plumbing for the robot to fry at a later date...
Anxious and excited at the same time...

If the team decide to hit both AVM's at the same time, i'm not sure, as I expect they aren't either, but, has anyone got any ideas on that? He said otherwise they may wait 9 months before coming back to have a go at the other one...
