Summary
Hypothermic machine perfusion (HMP) offers improved liver graft preservation compared to static cold storage, reducing complications and enhancing patient survival in liver transplantation. Further research and overcoming challenges will expand HMP use.
Area of Science:
- Hepatology
- Transplantation Medicine
- Organ Preservation Technology
Background:
- Ex-vivo machine perfusion, specifically hypothermic machine perfusion (HMP), is a developing alternative to static cold storage (SCS) for liver grafts.
- Over the past decade, HMP has shown promise in improving liver graft preservation and transplant outcomes.
Purpose of the Study:
- To review the mechanistic advantages of HMP for liver graft preservation.
- To highlight the clinical outcomes of liver transplantation utilizing HMP technology.
- To discuss the future potential and challenges of HMP in liver transplantation.
Main Methods:
- Review of existing literature on hypothermic machine perfusion for liver grafts.
- Analysis of single-centre studies and ongoing randomized controlled trials (RCTs).
- Examination of perfusate biomarker analysis during HMP for predicting early allograft dysfunction (EAD).
Main Results:
- Single-centre studies indicate HMP reduces biliary complications and early allograft dysfunction (EAD) rates.
- Improved patient survival has been observed in liver transplant recipients receiving HMP-preserved grafts.
- Perfusate biomarker analysis during HMP shows potential for predicting EAD.
Conclusions:
- HMP technology presents a significant advancement in liver graft preservation.
- HMP has the potential to expand the donor liver pool and improve transplant outcomes.
- Addressing regulatory, logistical, and financial hurdles is crucial for broader clinical adoption of HMP.
