The purpose of this prospective study was to demonstrate changes in blood flow of transplanted liver from intraoperative period to first postoperative day. Four female, six male, total ten liver recipients, aged 1 to 65 years (mean 31.4 years), were included in this study group. 8 recipients underwent living related partial liver transplantation and 2 recipients underwent cadaver liver transplantation. Patients who had elevated liver functional test values in the first postoperative day were excluded from this study. Intraoperative and first postoperative day blood flow measurements were recorded by using ultrasound as arterial peak systolic velocities, portal vein and hepatic vein flow velocities and resistive indices from hepatic artery. There were no statistically significant difference in intraoperative velocities of hepatic arteries, portal vein and hepatic veins compared with the postoperative values. On the other hand, resistive indices of hepatic arteries demonstrated significant decrease on the first postoperative day (p= 0.028). Our results demonstrated that resistive indices obtained from hepatic arteries tended to decrease on the first postoperative day compared with intraoperative measurements in the transplanted livers whereas other Doppler ultrasonography findings remained stable.
