Descrição
Transvaginal endosonography is now currently used in obstetrics and gynecology practice and seems a promising tool for essential studies on first trimester pregnancy. High-resolution and duplex/color Doppler in vaginal probes have brought to light new chances for early investigations on embryonic-fetal haemodynamics. We report our experience in this field, together with a review of the literature, giving an overview on embryonic-fetal cardiovascular haemodynamics studied by this approach. Blood flow patterns of intracardiac flows as extra-cardiac circulation during first trimester pregnancy are reported.
