Organ preservation milestones and basic principles

Abstract EN

Current shortage in organ donors led to the expansion of criteria for organ donation placing organ preservation as one cornerstone for successful transplant, graft function and survival.

The historical work of Belzer and Collins paved the way for key descriptions of physiopathology of cell ischemia and protection (cytokines roles, oxidative stress, energy shift to lactic acidosis and perfusion pressure changes).

Good preservation means immediate recovery of function and prevention of chronic rejection.

Two cooling approaches are available : static (SCS : simple cold storage) suitable for all organs, and dynamic (HMP: hypothermic machines perfusion) designed for kidneys and liver.

A thorough discussion of historically manufactured and widely sold preservation solutions e.g.

EuroCollins, UW solution (Viaspan®) as well as current used solutions e.g.

Custodiol® and the new Celsior is available in this review.

Obviously, every single organ exhibits different tolerance to warm and cold ischemia depending on its nature and demands after transplant.

Future perspectives of organ preservation may be hidden in hibernators which may hold the enigmas of perfect human organ preservation.
