Jugular vein and carotid artery blood flow in fetuses with increased nuchal translucency at 10–14 weeks' gestation

The aim of our study was to obtain measurements of the jugular vein and carotid artery pulsatility index (PI) at 10–14 weeks' gestation in chromosomally normal and abnormal fetuses with or without increased nuchal translucency (NT), in order to explore whether a relationship exists between increased NT and overperfusion of the head.
