Clinical Trial Summary

Interest of oxygenated hypothermic perfusion in preservation of hepatic grafts from expanded criteria donors.

Clinical Trial Description

The excellent results of liver transplantation (LT) have led to a significant increase in the number of patients awaiting transplantation. At the same time, the number of grafts remains stable. To extend the donor pool, the use of Extended Criteria Donor (ECD) donors graft increased each year despite the fact that these graft are known to be more vulnerable to ischemia-reperfusion injuries induced by cold storage preservation (CS). Their use is therefore associated with a greater risk of postoperative dysfunction of the graft. This risk can be reduced by improving preservation quality.

The preservation by hypothermic oxygenated perfusion (HOPE) consists of keeping the graft in hypothermia (4 to 12 °C) on an machine perfusion (MP) using a specific solution, saturated with oxygen. In kidney transplantation, the use of MP has been shown to improve graft function as well as graft survival, especially for ECD grafts.

In liver transplantation, experimental studies on animal models have demonstrated the superiority of HOPE over CS regarding graft function and survival. These results have been confirmed in humans on small retrospective series.

As HOPE is an expensive procedure, obtaining evidence of its effectiveness could result in a reimbursement of the additional cost. ;
