Our results and the review of literature suggest that absence of the ductus venosus is associated with a high incidence of fetal anomalies and adverse outcomes, including associated malformations, chromosomal aberrations, in utero heart failure and absence of the portal vein. Heart failure and absence of the portal vein seem particularly frequent when absence of the ductus venosus is associated with a connection of the umbilical vein to either the inferior vena cava or the right atrium.
Current two-dimensional ultrasound in expert hands allows an accurate diagnosis of craniofacial abnormalities from early gestation. In our hands, three-dimensional ultrasound did not add any valuable diagnostic information. Three-dimensional ultrasound may facilitate the understanding of the lesion by the parents and facilitate communication with the plastic surgeons. However, these potential benefits need to be carefully weighed against the costs of the ultrasound instrumentation, increased examination time and training of personnel.
Oral communication abstractsConclusions: In this study pregnancies complicated by HG had a favorable outcome, with a similar risk of twin pregnancy, a higher chance of viability and lower risk of early pregnancy failure when compared to asymptomatic controls. We conclude that an ultrasound scan is not clinically necessary in women presenting with HG.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
