Response to morticians and surgeons
It is strange, in a way this is both a mortuary practice and a surgical practice. The patient resembles a dead person more than a living person, so the mortician's experience might be more relavent. But the outcome actually matters, which is the surgeon's specialty.
While we do care a lot about neural structure, damaging a few surrounding blood vessels that aren't necessary to the preservation of the brain would not be something a cryonicist would tend to care about. There has already been some success regrowing new blood vessels in the lab, and most likely cryorevival will involve regrowing the entire body around the brain anyway.
The trouble is, if something goes wrong you don't want it to be something that could scramble the brain and muck up your identity. All the blood vessels of the brain bursting could do it, waiting an extra hour could do it. We can hope these things are reversible -- but we need to prevent them whenever possible, because we don't know for sure how reversible they are.
