We describe Doppler signals in artery-to-artery anastomoses of two monochorionic twin pregnancies. Flow velocity waveforms demonstrated cyclic changes in systolic velocities with intermittent reversal of end-diastolic velocities. A computer model showed that this was the result of two opposing pulsatile blood flow waveforms with different velocities and frequencies.
我们描述了两例单绒毛膜双胎妊娠动脉-动脉吻合处的多普勒信号。血流速度波形显示收缩期速度呈周期性变化，舒张末期速度间歇性反向。计算机模型显示，这是两个具有不同速度和频率的相反搏动性血流波形的结果。
