[Chorionic villus sampling in multiple pregnancies].
Prenatal genetic diagnosis is recommended in multiple pregnancies because of the increased prevalence of genetic abnormalities in such fetuses. It can be done early by chorionic villus sampling or later by amniocentesis. Several studies have demonstrated the efficacy and safety of chorionic villus sampling in multiple pregnancies. Our study describes the results of this method in a twin pregnancy and in 3 triplet pregnancies, which represent 3% of the chorionic villus samplings performed in our ultrasound unit during 1989-95. All genetically deformed fetuses in these pregnancies were identified by chorionic villus sampling and the method was not associated with fetal loss. Our results confirm the safety and efficacy of chorionic villus sampling as expressed in the world literature.
