Pets can be perfused with cryoprotectant immediately after euthanasia by a qualified veterinarian at the Alcor facility, which assists in rapidly cooling the brain and tissue essentially from the inside-out, as opposed to a straight freeze, which cools from the outside, inward without the anti-freeze properties of perfusate.
Animals have a variety of different biological structures that vary between species. Thus, while perfusion of cryoprotectant (essentially medical-grade anti-freeze to limit damage from freezing) may provide better preservation of tissue during cryopreservation than a straight freeze, there are no guarantees or representations that the science will be advanced enough to provide any form of revival of a pet during an owner’s lifetime.
The cost difference for perfusion versus a ‘straight freeze’ is a result of the substantial added expense of the perfusate solution and the veterinarian’s time to perfuse the pet. Alcor is a non-profit and as such, does not make more of a ‘profit’ by conducting one procedure over another.
Perfusion preservation can only be done at the Alcor facility and scheduled ahead of time. Perfusion and cryopreservation of a pet include the cost of euthanasia at the Alcor facility and the euthanasia procedure and perfusion are done by a qualified veterinarian. Field procedures done outside of our facility are not currently available.
