Living Donor Liver Transplantation Counseling for Patients with Moderate to High MELD Scores

Introduction to LDLT Benefits

The European Association for the Study of the Liver (EASL) guidelines state that to reduce mortality on the liver transplant waiting list, implementation or expansion of living donor liver transplantation (LDLT) programs should be considered, with 97% consensus 5
Patients with a Model for End-Stage Liver Disease (MELD) score of 23 have a significant short-term mortality risk, approximately 15-20% 3-month mortality without transplant, and may benefit from LDLT 3

A MELD score of ≥15 is the established threshold for transplant listing because patients below this score have better 1-year survival without transplantation, according to the Journal of Hepatology 1, 2, 3
At a MELD score of 23, the patient has a moderate to high risk of short-term mortality, and LDLT may offer a survival benefit 3

Waiting for a deceased donor transplant exposes the patient to progressive decompensation, with a risk of developing MELD exceptions (hepatic encephalopathy, refractory ascites, hepatorenal syndrome) that worsen outcomes 1, 4
The risk of developing portal hypertension complications (variceal bleeding, ascites, hepatic encephalopathy) can increase while waiting for a transplant 4

Donor safety is imperative and cannot be compromised, with evaluation following established protocols including liver anatomical, parenchymal, and volumetric assessment, according to the EASL guidelines 5
The live donor liver remnant must be at least 30% of the pre-donation volume or mass, as recommended by the EASL guidelines 5

The patient should be listed for deceased donor transplant while simultaneously pursuing LDLT evaluation, allowing for a dual-list strategy 5
If a suitable living donor is identified, the patient should proceed with LDLT without delay, as this optimizes timing before further decompensation 4

LDLT allows for scheduled, elective surgery when the patient is optimized, rather than emergency transplant during acute decompensation, which can improve quality of life 7
Avoiding prolonged waiting periods can prevent the development of complications (hepatic encephalopathy, refractory ascites) that severely impair quality of life 7
