First Trimester Transvaginal Sonographic Diagnosis of Fetal Anomalies

Ultrasonography in the detection of fetal anomalies in early pregnancy

“…Rottem et al 35 investigated the ability to diagnose fetal abnormalities in the first trimester with transvaginal sonography. They examined 141 pregnant women, who were at high risk of fetal abnormalities due to previous pregnancy complications, by performing transvaginal sonography between 9 and 12 weeks of gestation.…”

“…There have been several reports demonstrating the feasibility of abnormality detection in high risk populations, but most of these studies have not assessed the sensitivity of the technique (Table 2 35–37,46–48 ). We have investigated the performance of anomaly scanning in a low risk population49.…”

Hyperclarté nucale et hygroma cervical au premier trimestre de la grossesse : diagnostic prénatal et devenir néonatal

“…L'échographie foetale du premier trimestre par voie abdominale ou endovaginale, outre l'avantage qu'elle a de dater la conception, d'identifier les grossesses multiples, de dépis-ter des anomalies majeures, permet un examen morphologique de qualité [1]. L'étude échographique de la nuque foetale à la fin du premier trimestre a pris un grand intérêt du fait d'une relation bien démontrée entre les anomalies de la nuque foetale (hygroma cervical et hyperclarté nucale) et l'existence d'anomalies chromosomiques foetales [2][3][4][5][6].…”

Screening for Fetal Anomalies in the 12th week of Pregnancy by Transvaginal Sonography in an Unselected Population

“…Several case reports and the results of those centres where routine screening has been performed in a high-risk population have proved the accuracy of TV sonography in early diagnosis (Benacerraf et al, 1988;Rottem et al, 1989; Cullen *Correspondence to: Dr L.
