Overview of Memorial Hermann Liver Transplant Services
Memorial Hermann Health System operates one of the largest and oldest transplant networks in Texas, with comprehensive evaluation and care for adult and pediatric liver candidates. The program is integrated across multiple hospitals, including Memorial Hermann-Texas Medical Center and Memorial Hermann Specialty Care & Transplant Institute, supported by a multidisciplinary team of hepatologists, surgeons, anesthesiologists, coordinators, and social workers. This overview explains how the system works, who may qualify, and what to expect before, during, and after a liver transplant, using current clinical practice and publicly reported program information.
What Is a Liver Transplant and When Is It Needed
A liver transplant is a surgical procedure that replaces a failing liver with a healthy liver from a deceased or living donor. It is considered when chronic liver disease leads to decompensation, life-threatening complications, or irreversible failure and other treatments no longer control the condition. Common causes include cirrhosis from hepatitis B or C, alcohol-related liver disease, nonalcoholic steatohepatitis (NASH), autoimmune liver diseases, and certain inherited or metabolic liver disorders. Transplant evaluation at Memorial Hermann aims to determine whether transplantation is the best option and whether a candidate is medically and socially prepared for the process.
Indications That May Lead to Transplant Listing
- Persistent jaundice, ascites, or hepatic encephalopathy despite medical therapy
- Recurrent or refractory complications such as variceal bleeding
- Decompensated cirrhosis with declining liver function tests and quality of life
- Liver cancer (HCC) within specific treatment and staging criteria
- Certain inherited or metabolic liver diseases that progress to failure
How the Memorial Hermann Transplant Evaluation Works
Evaluation is thorough and designed to assess medical suitability, psychosocial readiness, and logistics. The process typically begins with a referral from a hepatologist or primary care provider, followed by a multi-step review by the transplant team. Candidates undergo testing across several domains, including liver disease severity, cardiovascular and kidney function, cancer screening, infectious disease, nutritional status, and psychosocial factors. The goal is to create a complete picture of risk and to optimize health before listing, when possible.
Key Components of Evaluation
| Evaluation Domain | Verified Detail | Source Type |
|---|---|---|
| Medical History and Exam | Comprehensive review of liver disease, comorbidities, and surgical risk | Clinical assessment |
| Liver Severity Scores | MELD-Na and Child-Pugh scores used to prioritize and predict outcomes | Clinical scoring systems |
| Cardiopulmonary Testing | Stress testing, echocardiography, and pulmonary function tests | Diagnostic testing |
| Cancer Screening | Imaging and tumor markers as indicated to exclude active malignancy | Guideline-based screening |
| Psychosocial and Social Support | Assessment of support network, adherence capacity, and housing stability | Clinical interview |
| Nutritional and Infectious Disease Assessment | Evaluation of malnutrition, obesity, and treatable infections | Laboratory and clinical review |
Liver Allocation and Waitlist Process
Once listed, candidates in the U.S. are matched through the national organ allocation system managed by the Organ Procurement and Transplantation Network (OPTN), with which Memorial Hermann is fully integrated. Donor livers are allocated based on medical urgency, geography, and compatibility, aiming to maximize life-years saved and minimize waiting time disparities. Wait times vary by blood type, region, and disease severity, with higher MELD scores generally indicating higher priority. During this period, the transplant team continues to manage the candidate’s care and may adjust treatment to maintain stability.
What to Expect During and After Surgery
When a compatible liver becomes available, the transplant team prepares the candidate and performs the operation, typically lasting several hours. The new liver is placed, blood flow is restored, and bile ducts are connected to the intestine. Immediate postoperative care occurs in a specialized transplant unit, where clinicians monitor for bleeding, infection, primary nonfunction, and rejection. Immunosuppressive medications are started to prevent organ rejection and are carefully managed over time. Recovery includes hospital monitoring, rehabilitation, and gradual return to daily activities, with frequent follow-up in the first months after discharge.
Immediate Postoperative Priorities
- Close monitoring of liver function through blood tests and imaging
- Management of immunosuppression and prevention of infection
- Early mobilization and attention to nutrition and mental health
- Careful tapering of medications and coordination with outpatient teams
Long-Term Follow-Up and Lifestyle Considerations
Long-term success after liver transplant depends on consistent medical care, adherence to medications, and healthy habits. Regular visits to the transplant clinic help monitor liver function, manage immunosuppression, screen for complications such as recurrence of liver disease or new cancers, and support overall wellness. Vaccination, infection precautions, and careful medication reconciliation are ongoing priorities. Many people return to work, school, and family roles, though ongoing medical follow-up remains essential. Memorial Hermann coordinates care with primary providers and specialists to support a stable, high-quality life after transplant.
Eligibility Criteria and Limitations at a Glance
While protocols may evolve, the following table summarizes commonly applied criteria and limits used in transplant assessment. Specifics can vary by program and are confirmed during evaluation.
| Attribute | Verified Detail | Source Type |
|---|---|---|
| Age Considerations | Evaluation considered on a case-by-case basis for older adults and younger candidates | Program policy |
| MELD Score Thresholds | Priority increases with higher MELD-Na scores; specific cutoffs set by OPTN | OPTN policy |
| Controlled Liver Cancer | May be considered within tumor size and stage criteria (e.g., Milan criteria) | Clinical guidelines |
| Cardiovascular Disease | Significant disease must be optimized or treated before listing | Program evaluation |
| Substance Use | Active substance use may temporarily defer listing; sobriety requirements apply | Program policy |
| Geographic Service Area | Coverage and referral pathways vary by county and hospital location | Facility-specific |
Common Questions and Practical Takeaways
Many patients and families want to know how to prepare, what risks are involved, and what life looks like after a liver transplant. Key takeaways include the importance of early referral, completing the evaluation thoroughly, maintaining consistency with medical care, and planning for post-transplant support. Because transplant eligibility and wait times depend on many dynamic factors, ongoing communication with the transplant team is essential. Memorial Hermann coordinates transplant care with a network of hospitals and specialty services to provide continuous support across the treatment journey.
