HDlive Flow with HDlive Silhouette for Diagnosis of Velamentous Cord Insertion

Abstract

Velamentous cord insertion is often associated with various complications during pregnancy and labor. Color Doppler ultrasound is a useful diagnostic tool for the prenatal diagnosis of velamentous cord insertion. HDlive flow with HDlive silhouette is the latest imaging modality consisting of power Doppler and grayscale technologies, and it provides additional information on normal and abnormal placental and umbilical cord blood flow. In the first case of velamentous cord insertion, HDlive flow with HDlive silhouette clearly showed a fork-like attachment of the umbilical cord on the fetal membrane near the placenta. In the second case of accenturiate placenta with velamentous cord insertion, HDlive flow with HDlive silhouette clearly revealed the number and direction of aberrant vessels on the fetal membrane connected to both placentas (mangrove-like attachment of umbilical cord). HDlive flow with HDlive silhouette may be a useful diagnostic modality for the precise prenatal diagnosis of velamentous cord insertion.
