Donor Recruitment and Selection for Adult-to-Adult Living Donor Liver Transplantation in Urgent and Elective Circumstances

    Summary

    Background: Adult-to-adult living donor liver transplantation is becoming an alternative to cadaveric transplantation in urgent and elective settings. Donor selection crucially affects donor safety and recipient outcome.

    Objective: To present our algorithm of urgent and elective donor selection.

    Methods: Urgent selection is expeditious and protocol‑based. Elective selection permits a comprehensive process. Both include medical, psychosocial and surgical-anatomic evaluations. Liver volumes and vascular anatomy are evaluated with computerized tomographic angiography. Informed consent is obtained after painstaking explanations. Independent institutional committees review and approve all cases.

    Results: Between July 2003 and June 2004 we evaluated 43 potential live donors for 12 potential recipients (fulminant hepatic failure, n=5; chronic end-stage liver disease, n=6); primary graft non-function, n=1). Thirty-three candidates (76%) were excluded due to blood type incompatibility (n=14, 42%), incompatible anatomy (n=8, 24%) – including problematic volume distribution (n=2) or vascular anatomy (n=6) – psychosocial issues (n=4, 12%), or medical co-morbidity (n=7, 22%). Five recipients (FHF[1], n=4; chronic ESLD[2], n=1) were successfully transplanted from living donors. In the acute setting, two patients (FHF, PGNF[3]) died in the absence of an appropriate donor (cadaveric or living donor). In the elective group, one patient died of unexpected variceal bleeding and one received a cadaveric graft just before the planned living donor transplantation was performed. One candidate was transplanted overseas and two cases are scheduled. The ratio of compatibility for donation was 34% (10/29) for blood type-compatible candidates.

    Conclusions: Donor selection for living donor liver transplantation is a complex, labor-intensive multidisciplinary process. Most exclusions are due to blood type incompatibility or anatomic details. Psychosocial aspects of these donations warrant special attention.
