Group Leaders arent expected to spend any additional time in the community, and are not held to a set schedule. Its sensitivity for trisomy 21 approaches 99% but these tests do not provide information on other chromosomal aberrations [9]. Because fetal aneuploidy can affect any pregnancy, all pregnant women should be counseled and offered aneuploidy screening regardless of age. The potential for a fetus to be affected by genetic disorders that are not evaluated by the screening or diagnostic test should also be reviewed. Soft Markers Identied on Detailed Ultrasound Several markers identi!ed on second-trimester ultrasound examination are associated with increased . Generally studied soft markers include fetal ventriculomegaly (VM), choroid plexus cyst (CPC), absent or hypoplastic nasal bone, a thickened nuchal fold (NF), intracardiac echogenic focus (IEF), echogenic bowel, short long bones, pyelectasis, and single umbilical artery (SUA).

SUMMARY: Soft markers are ultrasound findings that do not represent a structural anomaly, may be a normal variant, but have been associated with increased risk for fetal aneuploidy. At this time, approximately half of cases will be normal, 30% will continue to have mild pyelectasis, and 15% will have more significant hydronephrosis. Isolated sonographic markers for detection of fetal Down syndrome in the second trimester of pregnancy. This educational content is not medical or diagnostic advice. CPC is found in approximately 2 to 4% of fetuses at 16 to 24 weeks of gestation usually as an isolated finding in otherwise normal low-risk pregnancy [1,20].

Diagnostic testing should not be recommended to patients with an isolated soft marker in the setting of a negative NIPT result [9]. I am anxious, terrified, confused, just hoping for good news. The NIPT analyses the cell-free DNA derived from the placental tissue in the maternal circulation. Ultrasound Obstet Gynecol.

First- or second-trimester screening should not be performed after NIPT.1 Using NIPT only as a contingent follow-up test avoids invasive testing and its associated risks in most women,29 although some models suggest that as many as one in 50 pregnancies with positive first- or second-trimester screening and normal NIPT results may have an undetected chromosomal abnormality.30 The contingent approach is supported by the Society of Obstetricians and Gynaecologists of Canada.7 ACOG and the Society for Maternal-Fetal Medicine note that NIPT can be used in low-risk populations,1 although positive predictive values are lower.

For example, the risk of a woman giving birth to a live newborn with trisomy 21 (Down syndrome) increases from one in 1,480 at 20 years of age to one in 85 at 40 years of age.1 Although the overall birth rate in the United States has declined, the portion of first births to women older than 30 years increased from 23.9% in 2000 to 30.2% in 2014.4,5 Because fetal aneuploidy can affect any pregnancy, all pregnant women should be counseled and offered aneuploidy screening regardless of age.1,6,7.

Because this type of screening biopsies the portion of an embryo that becomes the placenta, it is susceptible to false-positive and false-negative results attributable to mosaicism (aneuploidy in the placenta that is not present in the fetus).12 Therefore, women who have conceived via in-vitro fertilization and undergone preimplantation genetic screening should still be offered aneuploidy screening during pregnancy.1. Neurodevelopmental outcome of isolated ventriculomegaly: a prospective cohort study. Clinical experience of laboratory follow-up with noninvasive prenatal testing using cell-free DNA and positive microdeletion results in 349 cases. Chromosomal abnormalities affect approximately one in 150 pregnancies1 and are responsible for 50% of early pregnancy losses.2 Aneuploidy is the presence of one or more extra chromosomes or the absence of one or more chromosomes.3 The consequences of fetal aneuploidy vary from incompatibility with life to intellectual and physical disability.
