At 20 weeks of gestation, labour was induced because of fetal death in utero. Conclusions: Vanishing twin phenomenon occurred in a large proportion of twin pregnancies in this infertility population. Early β-hCG level increases are slower in vanishing twins than in singleton and twin pregnancies, with the slowest increases seen when the spontaneous fetal losses occur at earlier developmental stages. Objective: The mean age of patients with the chorionic bump was 33.1 years (range, 21–40 years), and the mean gestational age was 6.7 weeks (range, 5.8–9.3 weeks) at the time of sonography (Table). Figure 2 illustrates an early pregnancy with both a chorionic bump and subchorionic hematomas and shows the difference between the two.

The vanishing twin: an explanation for discordance between chorionic villus karyotype and fetal phenotype. First‐trimester screening for trisomy in pregnancies with a vanishing twin should rely on a combination of maternal age, fetal nuchal translucency thickness and serum free β‐hCG, as in singleton pregnancy, without the use of serum PAPP‐A. Vanishing twin syndrome occurring in later pregnancy may cause complications like premature delivery, sepsis due to the retained products of conception, excessive bleeding, coagulopathies (inability of the blood to clot), and an increased risk of disseminated intravascular coagulation (creation of blood clots in the small blood cells).

Together they form a unique fingerprint. 1). Pregnancies with vanishing twins demonstrated a significantly lower mean 2-day percent increase in β-hCG level than singletons and twins (114.3% vs. 128.8% and 125.4%, respectively).

True False • Vanishing twin syndrome occurs in up to 30% of pregnancies. USA.gov. At 20 weeks of gestation, labour was induced because of fetal death in utero. Fetal heart activity was not a reliable predictor of continuing fetal viability in early twin gestations. If youre pregnant, especially with multiples, your doctor might want to monitor your hCG levels to make sure theyre rising the way they should. In some cases, one fetus in a multiple pregnancy will die in the womb, and the fetal tissue will be condensed in its sac by the other twin, placenta, or mother, giving the appearance that the baby has literally disappeared. Chromosome marker studies on the parents' blood and chorionic villi confirmed both maternal and paternal inheritance of chromosomes in the CVS. Two-day percent increase in β-hCG level. Patient(s): The most likely cause of the discrepant CVS karyotype is the presence of an undetected degenerating dizygotic twin.

The vanishing twin : An explanation for discordance between chorionic villus karyotype and fetal phenotype. CVS involves taking a small sample of the fingerlike projections of the developing placenta. RESULTS: The vanishing twin has led to immediate flooding of cfDNA into the maternal plasma due to necrotic cytotrophoblasts, which in turn caused increased release of fetal DNA in a short time. 2010 Mar 5;123(5):555-8.
