“…Experiences with the fetal iliac angle measurement at the second trimester [67][68][69][70][71] can be useful at the first-trimester scan, but this statement is unproven yet. The fetal iliac bones can be visualized during the first-trimester scan; the angle between them can be measured (Fig.…”

Prenatal screening of fetal aneuploidy is a continuously and rapidly evolving area of research; there have been tremendous advancements over the past decades in prenatal screening for aneuploidy, especially during the first trimester. As there is extensive evidence that effective screening for major chromosomal abnormalities can be provided in the first trimester of pregnancy, recently we have changed our practice; the prenatal screening of fetal chromosomal aberrations has been moved and pointed to the first trimester. Besides the nuchal translucency, which is one of the most known ultrasonographic markers, there are other markers, which can be examined during the first trimester of pregnancy. To maximize the quality of sonography, increase the screening sensitivity, and decrease the range of false-positive rate, all of the first-trimester ultrasound markers have well-established criteria for the measurement. With the use of high standards of scanning, the early recognition of sonographic markers of chromosomal aberrations can be helpful in forward prenatal diagnosis. On the contrary, the early diagnosis makes the termination of the pregnancy possible with fewer complications, and there is time for planning of further follow-up and interventions.

First trimester ultrasound tests alone or in combination with first trimester serum tests for Down's syndrome screening

Test strategies that combine ultrasound markers with serum markers, especially PAPP-A and free ßhCG, and maternal age were significantly better than those involving only ultrasound markers (with or without maternal age) except nasal bone. They detect about nine out of 10 Down's affected pregnancies for a fixed 5% FPR. Although the absence of nasal bone appeared to have a high diagnostic accuracy, only five out of 10 affected Down's pregnancies were detected at a 1% FPR.

Prenatal ultrasonographic measurement of the fetal iliac angle during the first and second trimester of pregnancy

Abstract: The proven larger iliac wing angle in neonates with Down syndrome can be demonstrated sonographically during the pregnancy, especially in the first and second trimesters. This marker may be useful in prenatal screening or exclusion of trisomy 21.
