ABSTRACT

Orthotopic liver transplantation (OLT) is known to be associated with a precarious perioperative hemostatic state due to dysregulation of procoagulant and anticoagulant factors, endothelial injury, and inflammation. Transmission of inherited bleeding and clotting disorders from the liver donor to the recipient may further complicate hemostasis during and after transplantation. As a result, consideration of congenital coagulation disorders in the liver donor is a practical concern for donor selection. However, there is no clear consensus regarding selection of donors with known or suspected thrombophilia or bleeding disorders. While multiple case reports and retrospective studies, subject to reporting bias, describe donor-derived thrombophilic and bleeding disorders, there are no large studies in the adult liver transplant literature that examine the frequency of transmission, utility of donor screening, or clinical impact of donor hemostatic disorders. Based on the reported literature, we summarize our approach for donor selection with an aim to balance improved organ utility and optimal post-transplant outcomes.
