Acute Kidney Injury in Adult Living Donor Liver Transplantation Performed with Different Methods of Inferior Vena Cava Clamping Maneuvers

Objective. The aim of this retrospective study is to evaluate and compare the incidence of acute kidney injury (AKI), defined as increase serum creatinine (SCr) of 0.3 mg/dl or increase in SCr to >= 1.5 times from baseline within 48 hour, in adult living donor liver transplantation patients performed with total cross clamp vs side clamp of the inferior vena cava (IVC). Methods and Patients. Sixty adult living donor liver transplantation (LDLT) patients were divided into 2 groups: 30 patients in total IVC clamping (G1) and 30 in IVC side clamping (G2) during the anhepatic phase. Patients' characteristic, hemodynamic changes in percentage (%) as a result of different methods of IVC clamping, urine output during anhepatic phase were compared by using the Student t test, and the incidence of AKI were compared by using the chi(2) test between groups. P value < .05 was regarded as significant. Results. The negative impact of the 2 different ways of IVC clamping was significantly more severe in G1 compared to G2; consequently, the urine output of G1 was significantly less than G2. Although there was significantly more urine output of G2 during the anhepatic phase, the incidence of the postoperative AKI between groups was similar. Conclusion. The side clamp of the IVC had a significantly less negative impact on the hemodynamic parameters and provided sufficient urine output during the anhepatic phase (2.24 +/- 3.17 vs 0.39 +/- 0.33 mL/kg/h) compared to the total clamp of the IVC. But this favorable data did not protect the patient suffering from postoperative AKI in LDLT.
