Hepatic Vein Flow Index During Orthotopic Liver Transplantation as a Predictive Factor for Postoperative Early Allograft Dysfunction.

ObjectivesThe authors devised a hepatic vein flow index (HVFi), using intraoperative transesophageal echocardiography and graft weight, and investigated its predictive value for postoperative graft function in orthotopic liver transplant.DesignProspective clinical trial.Setting,Single-center tertiary academic hospital.ParticipantsNinety-seven patients who had orthotopic liver transplant with the piggy-back technique between February 2018 and December 2019.Measurements and main resultsHVFi was defined with HV flow/graft weight. Patients who developed early graft dysfunction (EAD) had low HVFi in systole (HVFi sys, 1.23 v 2.19 L/min/kg, p
