Velamentous Cord Insertion:  Video

 

Above.  VCI (velamentous cord insertion) near the cervical region.  This finding requires transvaginal ultrasound with color Doppler.  Suspected fetal vessels should be imaged in relationship to the ICO, and pulsed Doppler waveforms should verify fetal origin.
