How Much of the Liver Can Be Donated?
The amount depends on the donor's anatomy, the recipient's needs, and the surgical plan.
In many adult-to-adult living donor transplants, a substantial portion of the donor's liver may be removed.
Surgeons must ensure that enough healthy liver tissue remains in the donor.
They also need to consider the size of the transplanted portion in relation to the recipient's body size.
This is a highly individualized calculation.
The objective is to protect both individuals.
The donor must retain sufficient liver volume and blood supply.
The recipient must receive enough liver tissue to support their recovery and long-term health.
This balance is one of the most important aspects of living donor liver transplantation.
4. What Happens Before a Living Liver Donation?
The operation begins long before the patient enters the operating room.
Potential donors undergo a comprehensive medical evaluation.
This process is designed to determine whether donation is safe for the donor and suitable for the recipient.
It may include:
Blood testing: Doctors evaluate liver function, kidney function, blood counts, clotting ability, and other important health indicators.
Blood group compatibility: The donor and recipient's blood groups are assessed to determine whether the transplant is appropriate.
Imaging studies: CT scans and MRI examinations help surgeons understand the liver's size, structure, blood vessels, and bile ducts.
Cardiovascular assessment: The donor's heart and overall physical condition are evaluated to determine whether major surgery can be performed safely.
Infectious disease screening: Doctors investigate conditions that could affect the safety of transplantation.
Psychological evaluation: Specialists assess the donor's understanding, emotional readiness, and freedom from coercion.
Independent donor advocacy: In many transplant programs, a professional who represents the donor's interests helps ensure that the donor's welfare remains a priority.
The evaluation can take time.
This is intentional.
A transplant team must understand the risks before proceeding.
Even if a son desperately wants to help his father, doctors may determine that he is not an appropriate donor.
For example, certain medical conditions, anatomical differences, or insufficient remaining liver volume may make donation unsafe.
In such circumstances, refusing the donation is not a failure.
It is a necessary medical decision designed to protect the donor.
5. The Day of Surgery: Two Operations, Two Lives at Risk
Living donor liver transplantation is unusual because it involves two major surgical procedures.
The donor undergoes surgery to remove a portion of their liver.
The recipient undergoes surgery to remove the diseased liver and replace it with the donated portion.
Both procedures must be carefully coordinated.
The transplant team includes surgeons, anesthesiologists, nurses, technicians, and other medical professionals.
Each member has a specific responsibility.
The Donor's Operation
The surgeon accesses the liver through an abdominal incision or, in selected cases, through a minimally invasive approach.
The liver's anatomy is examined carefully.
Blood vessels and bile ducts must be identified and preserved appropriately.
The planned portion of the liver is separated and removed.
The remaining liver tissue must retain an adequate blood supply and drainage.
The removed portion is then prepared for transplantation.
The Recipient's Operation
The recipient's damaged liver is removed.
The donated portion is placed in the appropriate anatomical position.
Surgeons reconnect the major blood vessels and bile ducts.
These connections are essential.
The transplanted liver needs blood flowing into it and blood flowing out of it.
It must also be able to drain bile into the digestive system.
After the connections are completed, the transplant team monitors the organ's blood flow and function.
The operation may take many hours.
The complexity depends on the patient's anatomy, the severity of the disease, and the surgical circumstances.
For families waiting outside the operating room, those hours can feel endless.
6. The Surgical Scars: A Visible Reminder of an Invisible Sacrifice
The scars in the photograph are among its most striking features.
They remind viewers that major surgery leaves a physical mark.
A liver transplant is not a minor procedure.
Both donor and recipient may have substantial abdominal incisions.
The appearance of the scars depends on the surgical approach, the patient's anatomy, wound healing, and other individual factors.
For the donor, the scar represents the physical consequences of undergoing an operation to help someone else.
For the recipient, it may represent the beginning of life with a transplanted organ.
However, scars tell only part of the story.
They do not reveal the pain experienced during recovery, the anxiety surrounding possible complications, or the uncertainty that families may face.
They also do not indicate whether the transplant was successful.
A person can have a well-healed surgical scar while still requiring ongoing medical treatment.
Likewise, the presence of a visible scar does not automatically mean that someone experienced complications.
The most important measure of recovery is not how the incision looks but how well the individual is healing and functioning.
7. What Happens to the Son's Liver After Donation?
One of the most fascinating aspects of living liver donation is what happens after a portion of the organ is removed.
The remaining liver begins adapting to its reduced size.
Specialized liver cells increase their activity and undergo proliferation.
Over time, the liver increases in volume and functional capacity.
This is commonly described as liver regeneration.
However, the process should not be misunderstood.
The liver does not necessarily return to its exact original shape or anatomical configuration.
Instead, the remaining tissue grows and adapts to support the donor's metabolic needs.
The recovery process varies.
Some donors experience relatively rapid improvement in liver volume and function.
Others require a longer period.
Medical monitoring is important throughout recovery.
Doctors may order blood tests and imaging studies to assess liver function and healing.
Does the Liver Regenerate Completely?
The liver has an impressive capacity to restore functional mass, but the process is not identical in every person.
The final size and structure may differ from the original anatomy.
Recovery depends on factors such as:
-
The amount of liver removed.
-
The donor's age.
-
Overall health.
-
Blood supply.
-
Nutritional status.
-
Surgical complications.
-
Individual biological differences.
A donor should never assume that the liver's regenerative ability eliminates the risks of surgery.
It is a remarkable biological feature, but it does not make organ donation risk-free.
8. What Happens to the Father's New Liver?
The transplanted portion of the liver also undergoes growth after surgery.
