Plasmatic Factor V as a Predictor of Graft Dysfunction After Liver Transplantation

Factor V is a coagulation cofactor that is primarily produced by the liver. Previous data has suggested a correlation between factor V levels and graft dysfunction. The investigators hypothesize that Factor V may be a reliable biomarker for hepatic function after LT. Therefore, the aim of this study is to validate the use of Factor V as a predictor of graft dysfunction after LT. This is a single-center prospective validation study. Patients undergoing LT at the University Health Network will have plasmatic Factor V levels measured during postoperative week 1. Patients will be followed up to 12 months. The study outcomes will be early graft dysfunction, and graft and patient survival. Graft loss will be defined as need for retransplantation in the study period.
