There are many ways you can help children and their families get the care they need.
A liver transplant is an operation performed to replace a diseased liver with a healthy liver or a segment of a healthy liver. In some cases, it’s done in combination with other organ transplants, such as intestines or kidneys. The liver may come from a deceased donor or from what’s called a “living donor,” a family member or an individual who is willing to donate and is a suitable candidate.
A transplant offers a chance for independence and better quality of life. Frequent medical supervision is still necessary after a transplant, but this need does decrease over time. It is critical to understand that a transplant is a treatment, not a cure. Potential transplant recipients must be committed to transplantation as a form of treatment in order to manage the complexities of life post-transplant.
Several transplant centers around the world have developed the technique of living-donor liver transplantation, which has been very successful in children. Current data suggests that the results of living-donor liver transplants are at least similar to, and perhaps better than, deceased donor liver transplantation.
The basis for taking a part of a living person’s liver lies in the organ’s unique ability to grow back (regenerate) to its normal size. A part of the liver (a lobe) can be removed without causing any damage in liver function.
The operation on the donor to obtain a piece of their liver and the operation on the recipient to transplant the liver, are performed simultaneously, and the donor can expect to be in the hospital for approximately one week. Within one to two months, both the liver of the donor and the portion in the recipient regenerate to normal size.
The decision to pursue a living-donor transplant requires thoughtful consideration. At Boston Children’s Pediatric Transplant Center, this procedure is done in collaboration with Lahey Clinic. The adult donor undergoes an extensive evaluation at Lahey Clinic, and the surgery on the donor is performed at Lahey.
In most cases, the healthy liver will come from an organ donor who has just died. Either a whole liver may be transplanted, or a part of one.
While a liver transplant is the preferred treatment for many people with liver disease, there are not enough deceased donor livers to meet the needs of all potential recipients. Split-liver transplants involve dividing a deceased donor’s liver so two recipients (one small child and one adolescent or adult) may benefit from one liver donation.
A reduced-liver transplant is when a piece of a deceased donor liver is used for a smaller patient.
The liver’s unique ability to grow back to its normal size makes both split-liver and reduced-liver transplants possible.
The liver is the largest solid organ in the body. It is located in the upper right portion of the abdomen, near the stomach. The liver is divided into eight segments, making the lobes. It receives blood from two sources: the portal vein and the hepatic artery. The portal vein brings nutrients to the liver from the intestine, and the hepatic artery brings oxygen to the liver from the heart and lungs.
All in all, the liver performs more than 400 different functions that keep a person healthy including:
The liver may fail to function properly for multiple reasons. The most common reason for liver failure in children is biliary atresia. Other conditions include:
Liver transplantation is an option for individuals who are no longer responding to treatment or for those with advanced liver disease.
An evaluation is necessary to determine the risks and benefits of a transplant, identify potential problems, discuss the options of a living donor vs. deceased donor and identify the risks and benefits for potential donors.
If a child is being evaluated for a transplant, they will see a number of health care professionals from the Pediatric Transplant Center. The evaluation usually takes place as an outpatient, during which time the child undergoes a number of tests. These may include:
After these consultations and tests are complete, our liver transplant team meets as a group to determine whether the child is a good candidate for a liver transplant and to determine the best time for the child to be placed on the transplant waiting list. If he or she is a transplant candidate, we make sure the family is fully educated about the risks and benefits, and the child will be placed on the United Network for Organ Sharing waiting list, or in the case of a living donor, the transplant will be scheduled.
We are grateful to have been ranked #1 on U.S. News & World Report's list of the best children's hospitals in the nation for the third year in a row, an honor we could not have achieved without the patients and families who inspire us to do our very best for them. Thanks to you, Boston Children's is a place where we can write the greatest children's stories ever told.”
