Incidence of chromosomal abnormalities in 153 pregnancies with ultrasound detected fetal abnormalities.
One hundred and fifty-three patients with fetal abnormalities diagnosed on ultrasound were karyotyped between January 1992 and December 1993. There were 19 (12.4%) fetuses with chromosomal abnormalities. The risk of chromosomal aberrations in the malformed fetuses were increased in the presence of intrauterine growth retardation (15.4%), oligohydramnios (20%) and polyhydramnios (25%). Fetal karyotyping is thus essential in the management of such pregnancies.
