Title: Contributing factors and significance to high resistive index on Doppler sonography of the hepatic artery immediately after liver transplantation
Abstract: Objective To investigate the contributing factors and significance to high resistance flow at the hepatic artery detected on Doppler sonography immediately after orthotopic liver transplantation.Methods Seventy-three patients who were examined on Doppler sonography consecutively after liver transplantation were divided into the normal resistive index (RI)group and the high resistive index group according to the RI measured after surgery.Several variances including trans- plant recipients,surgical procedures and complication after surgery were investigated.Results Seventeen(23%)of the 73 patients showed a temporal high resistive index at the hepatic artery during the first three days after transplantation.Older recipient and extended preservation time showed a statistically significant effect on the occurrence of a high resistive index at the hepatic artery immediately after transplantation(P0.05).Other variableness like gender of recipients,time of surger- y,time of warm ischemia,showed no statistical significance.The incidences of bile duct complications,vascular complica- tions and acute allograft rejection were not higher at the follow-up in patients with high-resistance flow than in those with normal flow.Conclusion High-resistance flow is freguently found in the Doppler sonography of hepatic artery during the pe- riod immediately after transplantation,and it is related to the recipient's age and the tine of ischemia.This finding has no prognostic value for early complications after surgery.
