Three-dimensional visualization of a fetal double aortic arch with HDlive color Doppler

The case shown here, illustrates a fetus with a double aortic arch. This is in our opinion a condition, which is often difficult to differentiate froma simple right-sided aortic arch as both cases are detected in general with the visualization on 2D and color Doppler of the transverse aortic arch with its course to the right of the trachea. Only a subtle transducer movement could demonstrate whether the right aortic arch is bifurcating into two arches or not, a plane difficult to get reliably in such conditions. The use of STIC with color Doppler enables the spatial demonstration of the vessels of interest. Due to the patent ductus arteriosus prenatally, three arches are seen; the right aortic arch, the left aortic arch and the ductal arch.

Prenatal Diagnosis of Agenesis of Ductus Venosus: A Retrospective Study of Anatomic Variants, Associated Anomalies and Impact on Postnatal Outcome

Brigitte Strizek et al.

Retrospective study of 119 cases with agenesis of ductus venosus diagnosed by prenatal ultrasound in two tertiary referral centers from 2006 to 2014. The type and location of the umbilical venous drainage site was noted. Charts were reviewed for associated structural or chromosomal anomalies, pregnancy outcome and postnatal course.
