Assessment of pericallosal artery at 11-14 weeks of gestation: Cohort study and meta-analysis

3D ultrasound angioscan with MV-Flow™: Enhancing fetal brain low-flow microvascular neuroimaging

MVFlow™ is a 3D algorithm that enhances the study of the microvasculature, useful in the study of tumoral lesions or in assessing the slow-flow of the placenta vessels and the developing fetal brain. It may improve the study of the corpus callosum in normal fetuses and be applied in the characterization of brain pathologies.

Ectrodactyly-ectodermal dysplasia-clefting syndrome. Prenatal prospective ultrasound diagnosis

OBJECTIVE

Prenatal diagnosis of the Ectrodactyly-Ectodermal dysplasia-clefting (EEC) syndrome has been based upon the detection of ectrodactyly, in association with facial clefting and/or positive family history. Our aim is to describe other ultrasonographic features indicating the presuntive diagnosis, regardless of genetic diagnosis, especially in cases of negative family history.

MATERIALS AND METHODS

A case report and a review of the literature was assessed.

RESULTS

Our case report showed a singleton foetus "lobster claw" deformities of hands and feet. Paternal history revealed bilateral agenesia of two fingers. Through literature, 15 case reports of prenatal diagnosis of EEC syndrome were found, 14 of which were eligible for our systematic review. The 33% of cases (5/15) had a familiar history of EEC, thus, we found one case of consanguinity of parents. Anomalies EEC-related were recognized in the 40% of cases (6/15). An association with genitourinary anomalies was found in 30% (5/15) of them.

CONCLUSIONS

A strong suspicion of final diagnosis of EEC may be done in the presence of ectrodactyly, facial clefting and urinary malformation especially in cases of negative family history. More attention should be given to a genetic counseling, especially to understand a possible relation to other genetic syndromes.

First-trimester ventriculomegaly in fetuses with callosal agenesis: Cause or association?

The sonographic findings in four fetuses presenting with ventriculomegaly at first-trimester ultrasound that were subsequently diagnosed as having agenesis of the corpus callosum (ACC) are described. The diagnosis of early ventriculomegaly was suspected subjectively by identification of increased cerebrospinal fluid within the lateral ventricles and confirmed by measuring choroid plexus-to-lateral ventricle length and area ratios. Subsequent scans revealed complete ACC in two cases and partial ACC in the other two. This report adds to the increasing evidence suggesting that first-trimester ventriculomegaly is a strong sonographic marker of underlying brain anomalies, including less evident malformations such as ACC. Detailed second-trimester fetal neurosonography in those women continuing their pregnancies should be performed.
