Successful Transplantation of a Liver from a Donor with HELLP Syndrome Undergoing Hypothermic Oxygenated Machine Perfusion (HOPE) Prior to Implantation.

ABSTRACT

BACKGROUND Liver transplantation (LT) has become the treatment of choice for patients with end-stage liver disease (ESLD). The organ shortage forced clinicians to use livers from donors with certain risk factors, so-called extended-criteria donor (ECD) organs. Hypothermic oxygenated machine perfusion (HOPE) is an alternative to conventional static cold storage and reduces early allograft injury in ECD organs. In this article we present the case of a 45-year-old man with hepatitis B virus (HBV)-associated cirrhosis and hepatocellular carcinoma (HCC) who underwent successful liver transplantation supported by pretransplant hypothermic oxygenated machine perfusion (HOPE) from a 34-year-old extended-criteria donor (ECD) with hemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome. CASE REPORT Liver transplantation was scheduled for a 45-year-old man with hepatocellular carcinoma (HCC) due to hepatitis B virus-induced liver cirrhosis. The organ donor was a 34-year-old woman who had developed intracerebral hemorrhage and brain death due to HELLP syndrome after delivery. Compared to the day of admission to the intensive care unit, a decrease in the donor's transaminases was observed prior to organ procurement. Before transplantation, HOPE was conducted after regular back-table preparation of the graft. LT was performed according to the standard surgical techniques and a standardized immunosuppressive regimen was conducted. In the post-transplant period, transaminases peaked directly after the operation and normalized after 1 week. No major surgical complications occurred. The patient was discharged after a 24-day hospital stay with normal liver function. CONCLUSIONS This case report supports the benefits of using HOPE in ECD organs and it should be considered in livers of donors with HELLP syndrome to improve post-transplant outcome.
