Principles of organ exchange Principles of organ exchange between EOEOsbetween EOEOs

• Organ exchange between European OEO‘s is Organ exchange between European OEO‘s is mainly „mainly „donor-drivendonor-driven“: “:

• Donor organ exchange only if no suitable Donor organ exchange only if no suitable recipient for this donor is available in donor recipient for this donor is available in donor countrycountry• Difficult to allocate donorDifficult to allocate donor

• Extended criteria donor (ECD)Extended criteria donor (ECD)• Rare blood group, size or ageRare blood group, size or age

• -> Reduction of loss of donor organs-> Reduction of loss of donor organs• -> No balancing of exchanged donor organs-> No balancing of exchanged donor organs
