Abnormalities of the Fetal Venous System

Evaluation of the fetal venous system has lagged behind other cardiac and arterial vascular assessment, but it has now become well recognized as a target for investigation in cases of circulatory compromise. A broad spectrum of malformations affecting this system has been described, including abnormalities of systemic and pulmonary venous return, as well as portal, umbilical, and ductus venosus abnormalities.
This session will review the anatomy of the fetal venous system and outline the abnormalities that may affect these structures as well as the associated adverse outcomes.
