...according to this front-page Reddit headline I just saw, which links to this Guardian article. I wonder if he's heard of KrioRus, whether he's signed up (Wikipedia says they offer services "to clients from Russia, CIS and EU"), and what his odds would be if he were (would it be possible to emigrate to Russia to be closer to the facility, and if not, what would be the best possible option?). Given his being a head of state, presumably it'd be pretty tough for an advocate to even get close enough to try to make the case.

Searching the Reddit comment thread for "cryo" turned up nothing.
