Every pregnancy is precious. However a pregnancy achieved through assisted reproduction techniques (ART) are even “more” precious.

Every pregnancy is precious. However a pregnancy achieved through assisted reproduction techniques (ART) are even “more” precious.

Therefore it is even more important to have a nuchal translucency screening, which will enable the patient to have an early assessment of risk for chromosomal abnormalities. This will help avoid unnecessary invasive procedures and also ensure that an early diagnosis of the fetus for potential heart problems is conducted.

Pregnancies achieved with assisted reproduction techniques are dated by deducting 14 days from the date when the embryo was transferred. This is to ensure that the dating takes into account the mother’s last menstrual periods.

In regards to the procedure, it is important to take into account whether any of the following have been used:

  • maternal eggs
  • egg donation
  • if  the embryo had been frozen and for how long
  • hormone fertility treatments

All of these factors are essential to ensure that the software produces the correct risk.

It is always recommended that all measures have been taken to ensure that quality control has been completed. This is even more important in cases of multiple pregnancies

With these pregnancies, the PAPP-A tends to be lower. Given that the risk calculation software will automatically take this into consideration, unless additional markers (nasal bone, triscupid flow, ductus venosus and uterine artery) are taken into account there is a higher risk of having a false positive result.

Generally, couples who have gone through assisted reproduction are more likely to ask for more detailed information.

Please find below the most recent researches on this subject:

 

  • in Denmark (2008)  of 1000 cases (216 Kb)
  • in Australia (2009) on 1700 cases (148 Kb)
  • Cardiac congenital defects in assisted reproduction (2010) (132 Kb)
