Abstract

Objective: To describe the ultrasound findings and its relationship with the cytogenetic study and the origin of the extra haploid chromosome set in four 69,XXX cases. Methods: Four pregnant women were referred because of abnormal 2nd trimester ultrasound. Karytoypes, FISH and DNA analysis were performed. Results: All cases presented asymmetrical intrauterine growth retardation, marked oligohydramnios and placental alterations and showed a 69,XXX karyotype. In three cases, DNA analysis allowed to establish the origin of the extra haploid chromosome set. Conclusions: At least three fetuses had a maternal extra haploid chromosome set. Thus, it has been possible to establish the main ultrasonographic markers and to observe the survival of the fetus until the second trimester when they have a maternal origin. Copyright (C) 2000 S.
