A case of mixed intrahepatic arteriovenous shunts in a fetus diagnosed at 35 weeks' gestation is presented. Color Doppler ultrasonography in the fetal liver demonstrated complicated vascular connections fed by the hepatic arterial branches and drained into the portal and middle hepatic veins. Pulsed Doppler ultrasonography identified a high cardiac output state by the detection of increased flow velocities of the great vessels. The contribution of Doppler ultrasonography to hemodynamic changes is highlighted. The management is briefly discussed.
本文报道了一例在孕35周时诊断出的胎儿肝内动静脉混合分流病例。胎儿肝脏的彩色多普勒超声显示，由肝动脉分支供血并引流至门静脉和肝中静脉的复杂血管连接。脉冲多普勒超声通过检测大血管血流速度增加，确定了高心输出量状态。强调了多普勒超声对血流动力学变化的作用。并简要讨论了治疗方法。
