Static cold storage becomes transplant's default (1960s onward)
For decades, surgeons have flushed donor organs with cold preservation solution and packed them in ice, slowing metabolism enough to buy transport time. Livers handled that way stay usable for well under a day. Every step from donor consent to implantation runs against that clock.
Cold storage made sharing organs across cities and regions routine.
It set the acceptance criteria surgeons still use, and made extended-criteria and donation-after-circulatory-death livers riskier to place.
VitaSmart is designed to replace part of that cold, oxygen-starved window with oxygenated machine perfusion, which is what the Canadian licence now permits.
