For individuals living with advanced liver disease or certain liver conditions, a liver transplant could make a huge difference in their overall quality of life. However, not everyone with liver disease will be suitable or eligible for a transplant.

In order to determine whether this major surgical procedure will benefit a patient, specialists need to take into account the severity of a patient's ongoing liver condition, overall health, and the potential for the patient to benefit from a transplant.

Understanding this process helps you recognise when a transplant may be considered and what specialists look for.

What Is a Liver Transplant?

A liver transplant is a surgical procedure in which a diseased or failing liver is replaced with a healthy liver from a donor. The donor liver may come from a deceased individual or, in some cases, from a living donor who donates a portion of their liver.

This procedure is performed to restore essential liver functions, including filtering toxins from the blood, producing proteins needed for clotting and supporting digestion.

When Is a Liver Transplant Needed?

A liver transplant may be considered when liver disease has progressed to the point where it can no longer be safely managed with conventional therapies.

Common situations where a liver transplant may be recommended include:

End-stage liver disease (cirrhosis): Long-term liver damage from conditions such as chronic hepatitis or fatty liver disease can lead to cirrhosis, where healthy liver tissue is replaced with scar tissue. As this condition advances, the liver gradually loses its ability to function.
Acute liver failure: This refers to a rapid loss of liver function, often occurring over days or weeks. It may be caused by severe infections, drug toxicity or other sources of sudden liver injury, and can become life-threatening without urgent treatment.
Liver cancer: A transplant may be considered for certain patients with primary liver cancer, particularly when the tumour meets specific clinical criteria.
Failure of other treatments: At times, medication or other long-standing forms of intervention for a liver condition may stop functioning, making transplantation a potential option.

Common Eligibility Criteria for Liver Transplants

Eligibility for a liver transplant is determined through a comprehensive assessment, typically conducted by a multidisciplinary team of liver specialists.

Specialist teams work to understand the unique circumstances of each patient, and examine a combination of clinical and personal factors to ensure that the procedure is appropriate and offers the best possible outcome for each individual.

Your Medical History

Not everyone will be eligible for a liver transplant, particularly if there are underlying conditions that may affect outcomes. These may include:

Medical conditions that significantly shorten life expectancy
Severe pulmonary hypertension
Ongoing drug or alcohol abuse
Other forms of cancer

These factors are thoroughly assessed during liver transplant eligibility checks, to ensure that a transplant can provide meaningful and lasting benefit.

Your Overall Health

A liver transplant is a strenuous operation, and your body needs to be strong enough to undergo surgery and recover safely. Doctors will evaluate your general health, including heart and lung function, to determine if you can tolerate both the procedure itself and post-transplant treatment.

Discipline and Commitment to Long-Term Care

Protecting your new liver requires long-term lifestyle changes. This includes avoiding alcohol and any activities that may harm the liver. Demonstrating the discipline to maintain these changes is an important part of the evaluation process.

You will also need to take medications for life and attend regular follow-up appointments to monitor your health. Following medical advice closely is essential to help prevent rejection and complications.

What Does a Liver Transplant Evaluation Involve?

The liver transplant evaluation process is comprehensive and involves multiple steps to determine the eligibility criteria mentioned above.

Initial Specialist Consultation

During this stage, you will meet a hepatologist or liver transplant specialist who reviews your liver condition in detail. This includes assessing your diagnosis and disease severity, past medical history, current symptoms and complications, as well as medications and lifestyle factors. The goal is to determine whether a liver transplant is appropriate or if other treatments should still be considered.

Blood and Laboratory Tests

A comprehensive set of blood tests is performed to evaluate liver and kidney function, blood clotting ability and the presence of infections such as hepatitis B, hepatitis C or HIV. These results are also used to calculate your Model for End-stage Liver Disease (MELD) score, a figure which helps determine how urgently you need a transplant and your priority on the waiting list.

Imaging and Organ Function Assessment

Imaging scans such as ultrasound, computed tomography (CT) scan or magnetic resonance imaging (MRI) are used to examine the liver, detect tumours and assess surrounding blood vessels. At the same time, your heart and lung function are evaluated through tests like electrocardiogram (ECG), echocardiogram or chest imaging to ensure you are fit enough to undergo transplant surgery.

Psychosocial and Financial Evaluation

In order to ensure that you are prepared, the transplant team will often need to carry out counselling and assessments to ensure that the patient understands the procedure. They will also use this opportunity to assess whether the patient has adequate caregiver support. It is also common for costs and financial coverage options to be discussed.
