If it was a massive stroke, this was a desperate attempt to save his life.
When you're on a blood thinner, it's a dreadful problem. You continue to bleed much more, and over a longer period of time.
You're more likely to die and, if you live, you're left with a more severe deficit.
This is the deadliest and most disabling form of stroke that we face.
They're completely in a state of suspended animation.
It sounds like this was a massive bleed, it sounds like he progressed rapidly to coma within the first couple of hours and I think the move to operate indicates that they were doing everything that they felt they could. It also indicates a certain measure of desperation.
