“…Our data obtained in early pregnancy, in a selected population, show that the incidence of isolated CPCs was 1·48 per cent, a rate quite similar to data reported in surveys of low-risk pregnant patients in the midtrimester (Achiron et al, 1991;Chinn et al, 1991;Perpignano et al, 1992) and in a recent prospective review (Reinsch, 1997).…”

“…The association between choroid plexus cysts and trisomy 18 has been debated exten sively in recent years [13][14][15][16]. In most cases, additional malformations were detected on ultrasonograpy; however, an incidence of 1:477 to 1:100 for trisomy 18 has been sug gested when choroid plexus cysts were the sin gle ultrasound-diagnosed anomaly [15,16], It appears that bilateral, large, late-appearing and persistent choroid plexus cysts are more commonly associated with aneuploidy.…”

Changing Dysmorphology of Trisomy 18 during Midtrimester

A fetus affected by trisomy 18 was observed serially on ultrasound from 14 to 21 weeks of gestation. The earliest and sole dysmorphic feature noted at 14 weeks of gestation were non-septated nuchal cysts. At 17 weeks the ultrasound examination was considered normal. However, at 21 weeks gestation, bilateral choroid plexus cysts, clubfoot, growth retardation and overlapping fingers were observed. These findings suggest that the dysmorphology associated with trisomy 18 is dynamic in nature and may change along the course of pregnancy.

“…Probably if the 'informed consent' is done correctly, explaining that in only a few cases is the presence of an abnormal Doppler analysis related to pathologies during pregnancy, the problem of maternal anxiety could be overcome. On the other hand this is a widespread attitude for prenatal diagnosis: to date many ultrasonographic markers of chromosomopathies have been identified, such as nuchal translucency, hyperechogenic cardiac foci, choroid plexus cysts and others [21][22][23][24][25]. In many of these cases a diagnostic amniocentesis is proposed even if, for example, the relation between hyperechogenic cardiac foci and chromosomopathies is rather low, ranging from 0 to 1% [26].…”

Objective: The aim of this study was to assess the value of uterine artery Doppler velocimetry performed at 18–20 and 22–24 weeks of gestation in predicting preeclampsia and adverse pregnancy outcome in low- and high-risk patients. Methods: 865 pregnant women were evaluated: 335 and 530 pregnant women represented the high- and low-risk groups, respectively. Doppler ultrasound examination of the uterine arteries was performed at 18–20 weeks of gestation in 385 patients and at 22–24 weeks of gestation in 659 patients. Pregnancy outcome was evaluated in terms of: onset of preeclampsia; birth weight <2,500 g; birth weight <1,750 g; delivery before 36 weeks, and delivery before 32 weeks. Results: At 18–20 weeks of gestation the sensitivity for the prediction of preeclampsia was 100 and 94% in low- and high-risk groups, respectively. Excellent negative predictive values towards birth weight <1,750 g (97% in low-risk and 93% in high-risk groups) and delivery prior to 32 weeks of gestation (99% in low-risk and 95% in high-risk groups) were obtained. At 22–24 weeks of gestation the sensitivity for the prediction of preeclampsia was 100 and 97% in low- and high-risk groups, respectively. Negative predictive values towards birth weight <1,750 g were 97% in low-risk and 94% in high-risk groups, whereas towards delivery prior to 32 weeks of gestation they were 98% in low-risk and 94% in high-risk groups. Conclusion: Doppler evaluation of the uterine artery at 18–20 and 22–24 weeks of gestation represents a useful predictive test in high-risk pregnancy and can also be used in prenatal surveillance of a low-risk population.
