New cross-sectional and longitudinal reference curves were established for the size of the neonatal lateral ventricles, which may allow for early identification and quantification of ventriculomegaly due to either posthemorrhagic ventricular dilation or periventricular white matter loss.

After completion of this article, the reader should be able to summarize the limitations of ultrasound and MRI in fetal CNS imaging, appropriately prepare and counsel patients regarding the best choice of imaging modality, and modify utilization of resources.

Our data provide first evidence that UVD-ratios allow risk prediction of pump twins. More early uncomplicated and late complicated cases are needed, for example, in a prospective trial, before the separation between uncomplicated and complicated cohorts is accurate enough to support a well-founded decision on (early) intervention.

ABSTRACT

(Gut 1995; 37: 639-642)

Objective: This study describes the association between the complexity of congenital cardiac and extracardiac malformations, and the parental decision of pregnancy continuation or termination. Methods: Congenital heart defects (CHD) was diagnosed by ultrasound in 251 fetuses before the 24th week (23 + 6 weeks) of gestation during the four year period from 2007 to 2010. All fetuses from the Utrecht region were referred to our center due to a strict referral pattern. The complexity and severity of the cardiac and possible extracardiac malformations were retrospectively categorized by a pediatric cardiologist and a perinatologist who were blinded to the pregnancy outcome. The groups with and without termination of pregnancy were compared using a univariate analysis and multivariate logistic regression. Results: In 119 (47%) of the 251 fetuses, parents opted for termination of pregnancy. In 103 of these cases (87%) there was a high complex or lethal cardiac, or a major or lethal extracardiac malformation. Of the 132 continued pregnancies, 42 fetuses (32%) had a high complex or lethal cardiac, or a major or lethal extracardiac malformation. There were significantly more terminations of pregnancy in case of a high or lethal complex cardiac or extracardiac anomaly (71 vs. 15%, p <0.001). Conclusion: Parents opted for termination of pregnancy significantly more often in cases with high complex cardiac and extracardiac malformations. It was rare for parents to opt for pregnancy termination in the absence of a severe cardiac or extracardiac malformation.
