Background A major prerequisite for living related liver transplantation is to ensure both donor safety and optimal graft quality. Therefore, excluding unsuitable donor candidates should be an important priority of the transplant team. Purpose To analyze the criteria for exclusion of potential living related liver donors. Patients and methods From November 2000 to March 2005, 327 potential living related donors for 136 potential recipients for liver transplantation were screened and worked up at the Liver Transplant Center, King Abdul Aziz Medical City. They were evaluated in a stepwise manner, including medical, physical, laboratory, psychosocial, and imaging assessment. Data regarding potential donors were retrospectively reviewed. Reasons for rejection of disqualified donors were analyzed. Results Out of the 327 potential donors, 223 (68.2%) were rejected at an early stage. A total of 104 cases (31.8%) had computed tomographic (CT) volumetry and/or magnetic resonance cholangiography (MRCP). While 44 (42.3% of those who had CT volumetry and/or MRCP) had their workup completed and proved to be suitable candidates, 24 (23%) went for surgery. Causes for donor rejection were classified as donor-related factors (inadequate volume, unsafe anatomy, abnormal liver function tests, medical/psychiatric, fatty liver, etc.; n = 191) and recipient-related factors (too ill, died, received cadaveric transplant, etc.; n = 112). Conclusion In our experience, as well as in those from other centers, a small proportion of potential donors prove to be satisfactory candidates. Therefore, strict adherence to a stepwise evaluation process is of utmost importance, so unsuitable potential donors can be disqualified, as early as possible during workup.
