Living and Deceased Liver Donation Criteria of Baskent University

Exp Clin Transplant. 2022 Aug;20(Suppl 4):80-87. doi: 10.6002/ect.DonorSymp.2022.O16.


Objectives: Both living and deceased donor transplants require appropriate donor selection to increase the success of liver transplants. Proper deceased donor criteria will also increase the use of discarded and marginal donor livers. Here, we evaluated the Baskent University deceased and living donor criteria.

Materials and methods: Since 1988, our team has performed 704 liver transplants (490 from living [69.6&] and 214 from deceased [30.4&] donors) at our 3 transplant centers (Ankara, Adana, Istanbul).

Results: Living donor evaluations follow from simple and noninvasive tests to more complex and invasive, including liver biopsy, with social and medical evaluations being the most important. Living donor candidates must be relatives of the recipient (up to 4th degree) or the spouse of the recipient, and candidates must be ≥18 years old, with no health problems. Candidates undergo computed tomography to assess arterial and venous anatomy, to estimate total and remnant liver volume, and to detect any abnormalities. If graft-to-recipient weight ratio is >1 and remnant liver volume is ≥40% of total liver volume, then the candidate is accepted for further evaluation. All living donor candidates undergo liver biopsy. Age is not important for deceased donor candidates, but biopsy is the most important criterion in deceased donor selection. After histopathological examination, both living and deceased donor candidates are rejected if they have chronic hepatitis, cirrhosis, severe hepatocellular injury, diffuse hepatocellular ballooning, or moderate-to-severe macrovesicular fatty changes >20%. Additional refusal criteria for deceased donors are hypernatremia, sepsis, extracranial malignancy, and high-dose vasopressor support.

Conclusions: A deceased donor is the first choice in organ transplant. Proper evaluations can decrease discard rates of deceased organs. Living donor liver transplants should be performed only at well-established centers with surgical teams who have appropriate medical expertise and adequate institutional resources. To reduce complications and provide adequately functional grafts, careful donor evaluation is imperative.
