    Abstract Background Whether the history of esophageal variceal bleeding (EVB) can be used clinically to predict the tolerability or hemodynamic instability during clamping of the inferior vena cava (IVC) and portal vein in liver transplantation is unknown and, therefore, needs to be elucidated. Patients and Methods A total of 50 anesthesia charts of patients who underwent living donor liver transplantation were reviewed, analyzed and compared retrospectively. Patients without a history of EVB were classified as group 1 and patients with a history of EVB were classified as group 2. The numbers of patients with a decrease in cardiac index (CI) of ≥20%, ≥30%, or ≥40% from their preclamping values after IVC clamping were compared with a χ2 , and a P value of .05 was regarded as statistically significant. Results The measured hemodynamic parameters before and 5 minutes after clamping of the IVC and portal vein were all significantly different in comparison with the patient's preclamping values. The incidence of a decrease in CI of ≥20%, ≥30%, or ≥40% 5 minutes after clamping of the IVC and portal vein were not significantly different between groups. Conclusions Clamping of the portal vein and IVC without performing veno-venous bypass in living donor liver transplantation had a significant negative impact on CI in both groups due to the drastic reduction in the venous return. Statistical analysis revealed that a history of EVB affects hemodynamics in a manner similar to that in patients without history of EVB during IVC clamping.
