The number of people waiting for a liver transplant has always been greater than the number of organs available from deceased donors. Many transplant centres now use living donors to help treat end-stage liver disease. In Canada, our centre performed the first parent-to-child and the first adult-to-adult liver transplants using living donors.
In parent-to-child transplantation, a parent gives a piece of liver (the left lateral segment) to their child. The donor is able to function without all of their liver, which regenerates to its normal previous size within a few months. The piece of liver that is transplanted grows along with the recipient and is able to meet all of the child's requirements.
In adult-to-adult transplantation, a person may be able to donate the right lobe (approximately 60 per cent) of the liver. The amount of liver transplanted must be appropriately size-matched. This is determined by doing CAT scans of the donor and estimating the weight of the right lobe graft, then comparing it to the weight of the recipient. The remaining segment in the donor will regenerate to its normal previous size within a few months. The transplanted liver segment grows in the recipient to the full size of a whole liver.
The best candidates for living liver donation are family members and close personal friends of the recipient. Anonymous living donors may also be considered.
Living donors should meet these criteria:
The potential donor will need to undergo several tests to ensure that the liver is working well. This usually takes about 8 weeks for each donor as a series of complex testing is required, including an ultrasound, echocardiogram, stress test, and different types of scans to determine the liver's size and shape as well as the condition of the bile ducts. Donors are thoroughly informed about the risks and are told that they can choose to decline at any time prior to surgery.
There could be some disadvantages to consider, such as:

PRELOD is a program in Ontario to help assist potential and actual living donors with some of the out-of-hospital expenses associated with their donation; for example, travel, parking, accommodation, meals, loss of income. PRELOD aims to reduce the financial burden incurred by living liver donors. There is eligibility criteria that donors must meet to obtain reimbursement. For further information about PRELOD, you can call 1.888.9PRELOD or 416.619.2342, or contact the PRELOD Administrator at PRELOD@giftoflife.on.ca.
