We measured the maximal velocity of the blood flow in the main portal trunk by duplex Doppler ultrasound in children suffering from a variety of liver diseases. The maximal velocity of the main portal vein in children with chronic active hepatitis and liver cirrhosis was decreased significantly as compared to those in control children (p < 0.01). The maximal velocity of the main portal trunk and K indocyanine green (ICG) had no significant correlation (r = 0.25, n = 27). The patient with the lowest portal velocity had esophageal and gastric varices with red color sign. We conclude that the measurement of the maximal velocity of the main portal trunk with duplex Doppler ultrasound is useful in evaluating portal hypertension in children.
我们通过双功多普勒超声测量了患有各种肝脏疾病儿童的肝门静脉主干血流最大速度。与对照儿童相比，慢性活动性肝炎和肝硬化儿童的肝门静脉主干最大速度显著降低（p<0.01）。肝门静脉主干最大速度与靛氰绿（ICG）无显著相关性（r = 0.25，n = 27）。门静脉速度最低的患者出现食管和胃静脉曲张并有红色征。我们得出结论，用双功多普勒超声测量肝门静脉主干最大速度有助于评估儿童门静脉高压。
