All physicians, nurses or midwives performing the NT scans were certified according to the Fetal Medicine Foundation (Snijders et al., 1998). : I'm just curious if anyone every experienced this before & went on to have a healthy baby. These findings are in agreement with our results. I am not saying this is what's going to happen to me but I just wanted to know if it was possible. We excluded all pregnancies conceived after FER (13 cases) because their first trimester screening markers have been shown to be significantly different from the screening markers in IVF/ICSI pregnancies, and are instead comparable with spontaneous pregnancies (Gjerris et al., 2008a,b), resulting in the exclusion of 13 cases of vanishing twin. From this cohort, we identified 78 cases of singleton pregnancies with an originally described co-twin. The early ultrasound scan is routinely performed at the fertility clinics to establish the presence of a live fetus in utero. The regression line and the 95% confidence interval are shown. Yey!

The overall study population is described in detail in a recent publication (Gjerris, 2008a). Does a âvanishing twinâ affect first-trimester biochemistry in Down syndrome risk assessment? However, as estimated by the above described figures, one case with a 20% lower PAPP-A MoM levels is not likely to have any impact on the overall results. One study concerning hCG as a tool for monitoring early pregnancy in fertility patients found that maternal serum hCG in pregnancies with a vanishing twin exhibited a slower rise of the serum concentration of hCG already from Day 12 of pregnancy when compared with normally progressing twin pregnancies. Eighteen Danish public and private fertility clinics and 10 departments of fetal medicine participated in the study. The study was supported by grants from the Danish Health Foundation (2006B034, 2005B055, 2004B149), The Danish Medical Research Council, The Augustinus Foundation and The Aase and Ejner Danielsens Foundation.

Only files 8MB or smaller of the following types are supported: JPEG, PNG, GIF. :). Likewise, no difference was seen for NT measurements. and with us … Several studies have found a higher rate of monochorionic twins in pregnancies conceived by ART compared with spontaneously conceived twins; however, this rate is still relatively small (Aston et al., 2008; Spencer et al., 2008). Did you see the twin on your first ultrasound? In those cases where the questionnaire was not returned, information was retrieved from the fertility clinic or from hospital records. In Europe, twin pregnancies conceived by assisted reproductive techniques (ART) occur in 22% of all pregnancies due to transfer of more than one embryo (Pinborg, 2005). If I were you and your HCG is still rising at the right rate I would remain hopeful. Despite increasing use of elective single-embryo transfer, double (or more) embryo transfer was in 2004 performed in more than 80% of all ART procedures (Andersen et al., 2008).

The aim of this study was to assess the impact of a âvanishing twinâ on first trimester combined biochemical and ultrasound screening in pregnancies conceived after IVF and intracytoplasmatic sperm injection. In the remaining nine cases, the spontaneous reduction occurred between the early ultrasound scan and the time of NT scan. A scatter plot illustrating the association between PAPP-A and free Î²-hCG for singleton and vanishing twin pregnancies is shown in Fig.Â 3. Hope the baby keeps on growing.

This again supports that the serum screening markers do not differ significantly between the groups. Now, with the common use of ultrasounds during pregnancy, embryos can be seen at their earliest, cellular level. 5 5. However, the overall altered levels of serum screening markers and the associated risk of a higher false positive rate should be taken into consideration when interpreting the results of risk assessment for use in genetic counselling in ART pregnancies.
