    ObjectivesPerioperative coagulation management in liver transplantation recipients is challenging. Viscoelastic testing with rotational thromboelastography (TEG) can help quantify hemostatic profiles. The current work aimed to investigate whether the etiology of end-stage liver disease, pretransplant disease severity, or pretransplant thrombotic or bleeding complications are associated with specific TEG patterns.DesignRetrospective cohort study.SettingSingle quaternary care hospital.ParticipantsA total of 1,078 adult liver transplant patients.InterventionsThe primary exposure was the etiology of end-stage liver disease classified as either intrinsic or nonintrinsic (eg, biliary obstruction or cardiovascular). Secondary exposures were patients' preoperative Model for End-Stage Liver Disease (MELD) score, Child-Pugh class, presence of major preoperative thrombotic complications, and major bleeding complications.Measurements And Main ResultsPatients with intrinsic liver disease (84%) showed higher odds of hypocoagulable (odds ratio [OR]: 3.70, 95% confidence interval [CI]: 1.94-7.07, p < 0.0001) and mixed TEG patterns (OR: 4.59, 95% CI: 2.07-10.16, p = 0.0002) compared with those with nonintrinsic disease. Increasing MELD scores correlated with higher odds of hypocoagulable (OR: 1.14, 95% CI: 1.08-1.19, p < 0.0001) and mixed TEG patterns (OR: 1.08, 95% CI: 1.03-1.14, p = 0.0036). Child-Pugh class C was associated with higher odds of hypocoagulable (OR: 8.55, 95% CI: 3.26-22.42, p < 0.0001) and mixed patterns (OR: 12.48, 95% CI: 3.89-40.03, p < 0.0001). Major preoperative thrombotic complications were not associated with specific TEG patterns, although an interaction with liver disease severity was observed.ConclusionsLiver transplantation candidates with intrinsic liver disease tend to exhibit hypocoagulable TEG patterns, while nonintrinsic disease is associated with hypercoagulability. Increasing end-stage liver disease severity, as evidenced by increasing MELD scores and higher Child-Pugh classification, was also associated with hypocoagulable TEG patterns.Copyright © 2024 The Author(s).
