Yesterday was a very tough day! I had no idea that they were going to drop a bomb on us like they did and I had no idea of the rollercoaster ride we were going to take.
After long delays and an upset boy (I had to lay into a very heartless pre-op nurse and remind her of the hospital's pediatric bill of rights) here is what happened:
1. The team called us away from Bo and told us that if we hadn't found this when we did and began intervention he would surely have died before reaching adulthood. This is due to the depth and location of the AVM based on the CT and MRI scans. It is deeper than first thought and just to the left of the posterior thalamus in the section that controls being awake.
2. There is no possibility of surgical resection because of where and how deep it is.
3. They can treat it but until they have a good map the risks are coma, death, and brain deficit at that point in time. The embolization could backfire and block the veins as well as the arteries and cause death of healthy tissue. The Gamma knife could do the same if the nidus is not outside the brain but again, without the map, they don't know for certain.
4. They asked us if we wanted to be conservative in treatment since we did find it early and they don't believe it will bleed prior to us completing treatment. We went ahead with the conservative route.
5. After a while we got a phone call from the OR saying that they were going to proceed with embolization which we took as a good sign.
6. The team came out to tell us that there had been a technical difficulty and they could not see as clearly as they wanted to due to the equipment not being set up the way the lead doc liked and that they stopped the procedure and we will continue as soon as everything is fixed but not more than two weeks delay.
7. They did get an excellent map of the AVM and part of the nidus is outside and part is inside. They will embolize one part and Gamma knife the other and it should be okay.
8. The AVM is being fed from the midbrain and lateral arteries which they said was good that it was only those.
9. My son is doing okay today with the exception of feeling tired and having a sore spot at the entrance which is to be expected.
I am just beyond exhausted right now and we are waiting to hear further (they said a day or two) about when we go for the next round.
