“…For amniocentesis in twin pregnancies, the fetal loss rates ranged from 0 to 6% up to 20 weeks and from 0 to 8% up to 28 weeks. For CVS in twin pregnancies, pregnancy loss rates were 2.3 to 3.1% up to 20 weeks and 1.7 to 3.1% up to 28 weeks 1 . Reports in triplet pregnancies focused on outcome of fetal reduction only but not on invasive testing.…”

“…For CVS in twin pregnancies, pregnancy loss rates were 2.3 to 3.1% up to 20 weeks and 1.7 to 3.1% up to 28 weeks. 1 Reports in triplet pregnancies focused on outcome of fetal reduction only but not on invasive testing. The objective of the present study was to review the outcome of twin pregnancies after amniocentesis in a university teaching hospital, so as to give a more comparable fetal loss rate in a local institution to counsel women regarding the risks of invasive procedures in multiple pregnancies.…”

“…As a result, maternal serum analyte screening is less reliable than with singleton pregnancies. Invasive prenatal testing is available for twin pregnancies, but CVS and amniocentesis are procedurally more complex and the risk for maternal and fetal complications secondary to the procedures is increased over that with singletons pregnancies (for review, see Appelman and Furman, 2005;Cuckle, 2000;Jenkins and Wapner, 2000).…”

We report on the prenatal genetic counseling and testing experience in 343 pregnancies with twin or higher multiple gestations. By self-report, 8% (27/343) parents of these pregnancies reported meeting with a genetic counselor, and 23% (79/343) elected prenatal genetic testing. The most common testing procedures elected were maternal serum analyte screening and amniocentesis to identify fetuses with aneuploidy or neural tube defects. Use of prenatal genetic testing was correlated with advanced maternal age. No association was found between use of genetic testing and use of OI/ART or the length of time needed to conceive. Forty percent (11/27) of those who met with a genetic counselor opted to decline prenatal testing/screening. These data suggest that although clients with multiple gestation pregnancies would likely benefit from genetic counseling, many are not availing themselves of this service. Implications of these data for the genetic counseling profession are discussed.

“…Malségrégation post-zygotique à la première division mitotique Certains auteurs évoquent la possibilité d'une grossesse dizygote avec une fusion des placentas très tôt dans la grossesse dans le cas de grossesses obtenues après fécondation in vitro [8]. Pour certains auteurs, si le risque est élevé pour un seul jumeau, une biopsie de trophoblaste peut être réalisée pour le jumeau anormal [15]. L'examen macroscopique du placenta avec la mise en évidence d'anastomoses peut affirmer la monochorionicité.…”
