Clinical Significance of Intraoperative Blood Flow into the Transplanted Liver in Early Allograft Dysfunction after Liver Transplantation / 中国医科大学学报

ABSTRACT

Objective To determine the risk factors associated with early allograft dysfunction (EAD) after liver transplantation. Methods We retrospectively analyzed the records of 138 patients who underwent liver transplantation from January 2006 to October 2016 in our department. Transplant recipients were divided into two groupsthose who met the diagnostic criteria of EAD (EAD group) and those who did not (non-EAD group). We compared blood flow into the transplanted livers and other clinical features between the two groups using univariate and multivariate analysis. Results Intraoperative portal vein flow (PVF) maximum was significantly different between the two groups. Multivariate analysis revealed that intraoperative PVF maximum ＜1 600 mL/min was the only independent risk factor for the occurrence of EAD after liver transplantation in this cohort. Conclusion Intraoperative PVF maximum ＜1 600 mL/min is an independent risk factor for the occurrence of EAD after liver transplantation. Measuring intraoperative blood flow into the transplanted liver in liver transplant recipients may help identify patients at risk for developing EAD.
