Curr Opin Obstet Gynecol. Cookie Notice Studies advocate serial fetal growth assessment when isolated echogenic bowel was detected at the first and the second trimester because it is associated with FGR and increase in intrauterine fetal demise (relative risk [RR] 1.6 for FGR and 8.6 for intrauterine fetal demise). I then paid for the harmony test and it came back low risk. Mild pyelectasis: evaluating the relationship between gestational age and renal pelvic anterior-posterior diameter. [30], isolated shorted HL and FL in second trimester demonstrated higher rates of preterm delivery and preeclampsia. [34] showed no statistically significant difference in aneuploidy rate, birth weight and incidence of FGR between isolated SUA fetuses and three vessel cord fetuses, and concluded targeted growth assessment should not be a routine practice. Pediatr Cardiol. Just looking for stories/to talk to someone on a more human level, Just a question, if you did find out there's something wrong, what would you do about it? Before 10 weeks' gestation, the percentage of fetal vs. maternal cell-free DNA circulating in maternal serum (the fetal fraction) may be too low to create a result. Coco, C, and Jeanty, P (2004). At 32 years of age, your age-related risk for trisomy 21 is 1:695. Controversially, diagnostic testing in setting of a negative NIPT screen with isolated soft marker is not recommended in other guideline [9]. In the systematic review and meta-analysis of Scala et al. We respect everyones right to express their thoughts and opinions as long as they remain respectful of other community members, and meet What to Expects Terms of Use. Perles, Z, Nir, A, Gavri, S, Golender, J, and Rein, AJ (2010). Sonographic markers of fetal aneuploidy--a review. For fetuses with urinary tract dilation
It is superior to first- or second-trimester serum screenings with fewer false positives and higher positive predictive values for trisomies 18 and 21. Magnetic resonance imaging can be used for further elucidation of cases with ventricular enlargement [18]. Diagnostic testing should not be recommended to patients with an isolated soft marker in the setting of a negative NIPT result [9]. Single Umbilical Artery, or the Two Vessel Cord: What Does it Mean? These no-call results may indicate an increased risk of aneuploidy.33 Of those women with no-call results, 50% to 80% will receive a reportable result on a repeat test.7,34 Low fetal fraction is more common in pregnant women who are obese, with 7% of women weighing more than 100 kg (220 lb, 7 oz) and 51.1% of women weighing more than 160 kg (352 lb, 12 oz) receiving fetal fractions too low to report at 11 to 13 weeks' gestation.35, Any NIPT test may have a false-positive, false-negative, or no-call result. 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. no further aneuploidy evaluation, noninvasive aneuploidy screening

[44] has provided some reassurance that there was no evidence of any serious long term bowel disease associated with isolated fetal echogenic bowel. My OB is the go to high risk doctor in our city and he said the test is so accurate that he isnt concerned about the markers he saw anymore. The role of ultrasound in women who undergo cell-free DNA screening. First-trimester nuchal translucency, NIPT, and first- or second-trimester serum testing can be performed in twin pregnancies. CPC typically regresses by 23 weeks regardless of karyotype [13]. Pretest counseling should include a discussion of baseline age-dependent risk, the potential for false-negative and false-positive results, the difference between screening and diagnostic tests, and what types of follow-up testing to expect.9 The use of decision aids (examples are available at https://www.psychosocialresearchgroupunsw.org/decision-aids.html) may improve a woman's ability to make an informed choice.10 All prenatal aneuploidy screening tests optimize detection rates (high sensitivity) and test for relatively uncommon conditions, resulting in high negative predictive values but low positive predictive values. What was the outcome? Soft Markers Identied on Detailed Ultrasound Several markers identi!ed on second-trimester ultrasound examination are associated with increased . Postgraduate Institute for Medicine (PIM) requires faculty, planners, and others in control of educational content to disclose all their financial relationships with ineligible companies. isolated echogenic intracardiac focus, echogenic bowel, urinary tract
When abnormal NIPT screening is discordant with (normal) invasive diagnostic testing, it may be attributable to. Keep in mind that an ultrasound done around the 20 th week often has signs of soft markers, or around 1 in 30. Negative NIPT but 2 soft markers seen on ultrasound I am anxious, terrified, confused, just hoping for good news. Were only 21 and have a 15 month old too. and isolated choroid plexus cysts, we recommend no further aneuploidy
I am glad your FISH results came back negative! Please keep me posted. Please update us when you know more. Hi everyone! The interpretation of isolated soft markers is summarized in Table 5.1,7,41,42 When multiple soft markers are found, referrals to maternal fetal medicine and genetic counseling are warranted.42. Multiple studies have since reported similar or better test performance across low- and high-risk populations.2528. Echogenic bowel resolves spontaneously in 19.7% of cases and the association with Down syndrome reported likelihood ratio of 5.5 to 6.7 [13]. J Ultrasound Med. The risk of fetal aneuploidy rises with increasing maternal age. It may be performed as primary screening or as a follow-up test to abnormal findings on first- or second-trimester screenings. The amnio is diagnostic and also tests for other genetic problems not tested by the NIPT (1-2% risk in each pregnancy). Discordant results, particularly when more than one aneuploidy is seen on NIPT and not confirmed by invasive diagnostic testing, may require a discussion with the patient regarding the risks and benefits of an occult malignancy workup.36,37, First- and second-trimester serum screening or first-trimester nuchal translucency alone can be used to screen women with twin pregnancies for aneuploidy, although detection rates are lower.1 In higher order pregnancies (triplets or more), serum screening is unvalidated, and only nuchal translucency alone can differentiate which fetus is potentially affected. Copyright 2020 by the American Academy of Family Physicians. All Rights Reserved. Breathe and you will get through this!! Isolated CPCs in fetuses with normal karyotypes do not affect child mental and motor development after birth [22]. I am 31 weeks and 32 years old. Group Leaders communicate with staff moderators and escalate potential violations for review, but they dont moderate discussions. At 17 weeks I went for an early anatomy scan and told everything fine except they saw an EIF on baby's heart. Gupta, G, Aggarwal, S, and Phadke, SR (2010). The NIPT measures the fetal cfDNA in the mother's bloodstream, which comes from the placenta. context of current maternal serum screening and cell-free DNA screening

P16.10: False-negative NIPT and the role of placental mosaicism Catania et al. Postgraduate Institute for Medicine designates this enduring material for a maximum of 0.25 AMA PRA Category 1 Credit(s). Therefore, karyotyping should be offered when thickened NF is observed [10]. Isolated pyelectasis was associated with an increased risk of congenital anomalies of the kidneys or urinary tract. Pediatr Nephrol. Therefore, a targeted ultrasound with particular attention to the fetal heart is reasonable when a thickened NF is identified after normal fetal karyotyping [25]. Women with positive results on aneuploidy screening should be offered referral for invasive diagnostic testing. She basically said that with the negative NIPT these soft markers findings dont change my chances. 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. First one is a "bright spot" on the heart and the second is one slightly enlarged kidney. In case of a positive result for toxoplasma infection in maternal serum, amniocentesis is performed to determine the presence of the pathogen in the amniotic fluid by amplification of DNA, using polymerase chain reaction [38]. The overall prognosis of VM strongly depends on both the extent of enlargement and/or the presence of other abnormal findings or structural malformations. [16], the fetuses with isolated unilateral VM had 0% chromosomal abnormalities, 8% congenital infection, and in about 5% of fetuses, there is progression of VM during the course of the pregnancy. Keep me updated! Absent of hypoplastic nasal bone, defined by a nasal bone that is not visible in first trimester or with a length of less than 2.5 mm in the mid-sagittal section of the fetal profile in second trimester, however the nasal bone length appears to be shorter in Korean fetuses than Caucasian and Chinese fetuses and is necessary to refer to race standards [39], and is described as one of the many phenotypic features of Down syndrome [6]. 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. The possible etiology is not yet fully understood, but it may be of placental origin. All identified conflicts of interest (COI) are thoroughly vetted and mitigated according to PIM policy.

Please specify a reason for deleting this reply from the community. It is essential to provide information to the parents about the observed soft markers and its potential impact on prenatal and postnatal life. Salomon, LJ, Alfirevic, Z, Audibert, F, Kagan, KO, Paladini, D, and Yeo, G (2014). SUA appears to be an isolated finding in 6080% of cases [4,33,34]. Aneuploidy is the presence of one or more extra chromosomes or the absence of one or more chromosomes. Physicians should claim only the credit commensurate with the extent of their participation in the activity. an educational tool, January 2022. The Welsh study of mothers and babies: protocol for a population-based cohort study to investigate the clinical significance of defined ultrasound findings of uncertain significance. Because fetal aneuploidy can affect any pregnancy, all pregnant women should be offered screening. Just had my anatomy ultrasound on Thursday and they found a EIF and bilateral pyelectasis. Regarding the location, 88% are found in the left ventricle and 5% in right ventricle. Dukhovny, S, Wilkins-Haug, L, Shipp, TD, Benson, CB, Kaimal, AJ, and Reiss, R (2013). I've been seeing a few posts on soft markers so I'm hoping this may make you feel a bit more at ease about it. In low risk populations for aneuploidy, the presence of an IEF is not an indication for invasive procedures and with negative FTS or NIPT it may be described as not clinically significant or as a normal variant. I am going in for a fetal echo at 28 weeks based on the recommendation from mfm. The risk of fetal aneuploidy rises with increasing maternal age. Cicero, S, Sacchini, C, Rembouskos, G, and Nicolaides, KH (2003). growth restriction, or additional soft marker following a detailed
CPC is a small sonographically discrete fluid-filled space 5 mm within the choroid plexus and CPC is seen as black echo-free areas. Patel, Y, Boyd, PA, Chamberlain, P, and Lakhoo, K (2004). I think you should figure out those questions first and then figure out your way of action. Echogenic bowel has been described as normal variant, but may be associated with congenital viral infections (particularly CMV), aneuploidy, intra-amniotic bleeding, severe uteroplacental insufficiency, meconium peritonitis, cystic fibrosis, anemia, and fetal growth restriction (FGR) [3,6,13]. The PIM planners and others have nothing to disclose. Describe the management of ultrasound soft markers if the aneuploidy screening result in negative, Estimated time to complete activity: 0.25 hours. She also told me the MFM clinic I'm going to does a lot of amnios and has never had a loss, and modern day risk averages 1:1000. In this low risk population, soft markers were found in 5.9% of fetuses at second trimester ultrasound; markers were isolated in 5.1%, multiple in 0.7%, and combined with anomalies in 0.1% [1]. Its sensitivity for trisomy 21 approaches 99% but these tests do not provide information on other chromosomal aberrations [9]. 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. Obstet Gynecol. A randomized controlled trial reported a detection rate for trisomy 21 of 87% at 11 weeks' gestation, 85% at 12 weeks, and 82% at 13 weeks.13, Abnormal nuchal translucency is also a predictor of subsequent structural anomalies, and all women with abnormal nuchal translucency should receive detailed ultrasonography at 18 to 22 weeks' gestation.7 The American College of Obstetricians and Gynecologists (ACOG) recommends fetal echocardiography in these cases. Although some soft markers can be occurred in a fetus as 2 normal variants, because of increased incidence in abnormal situations such as chromosomal and congenital abnormalities and.

She agreed false positives are a lot more common and basically said the test was so accurateat detectingtrisomy 21 (which all of my particular markers point to) that it would most likely be a case of human error. Trisomy 21, 18, 13 or an unbalanced autosomal structural abnormality are associated with relative short FL (risk 1:123; 95% CI, 79192) [31]. Relevant guidelines from the Society for Maternal-Fetal Medicine, American College of Obstetricians and Gynecologists, Society of Obstetricians and Gynaecologists of Canada, and Royal College of Obstetricians and Gynaecologists were reviewed. Fetal pyelectasis is defined as an anteroposterior measurement in a transverse scanning plane of 4 mm or larger in second trimester and/or 7 mm or larger in third trimester, whereas pelvic anteroposterior diameter 10 mm or larger is criteria for hydronephorosis [4,45].

Ill be 21 weeks pregnant with my second tomorrow, and at my 12 week NT scan the fluid was measuring 4.4mm which they like under 3mm so I did the NIPT. Fetal cell-free DNA testing (NIPT), which is generally performed at or after 10 weeks' gestation, is superior to first- or second-trimester serum screenings with fewer false positives and higher positive predictive values for trisomies 18 and 21. Soft markers were originally introduced to prenatal ultrasonography to improve the detection of trisomy 21 over that achievable with age-based and serum screening strategies. It has been estimated that between 0.5 to 2.8% of euploid fetuses will have images consistent with delayed ossification of the nasal bone in either first-or second trimester sonography [23].

Im very upset that for some reason I was not told about this second marker, as I definitely would have requested an amnio but it wasnt offered to me nor did they make any mention of the abnormalities both being markers. Identification of second trimester screen positive pregnancies at increased risk for congenital heart defects. First- and second-trimester serum screening or first-trimester nuchal translucency alone can be used to screen women with twin pregnancies for aneuploidy, although detection rates are lower. DiPietro, JA, Cristofalo, EA, Voegtline, KM, and Crino, J (2011). If the renal pelvis measures >7 mm at 30 week examination, postnatal follow-up is suggested [14,15]. God bless you and your baby. However, a few studies have suggested that diffuse echogenicity in the fetal heart, especially when the right ventricle is also involved, may signal a poor prognosis and deserves a further search for associated pathologies [27,28].
