P6B-10 Improved Investigation of Maternal/Fetal/Placental Vessels through Multigate Spectral Doppler

The assessment of the hemodynamics in the maternal and fetal blood circulation currently relies on the color doppler and spectral doppler US techniques. Although several studies have proven the reliability of such methods, the complex morphology of the investigated vessels still causes several limitations. An alternative, high resolution technique, named MSDA, has been recently introduced for the investigation of fetal-maternal circulation. This work reports several examples selected among the data collected on more than 150 healthy and pathological pregnancies over 1 year of multi-centre screening. The presented results suggest that MSDA represents a method suitable to improve the accuracy in predicting pregnancy complications and in detecting pathological events. Prospective studies are needed to determine the utility of this technique in predicting placenta mediated complications.
