ABSTRACT
OBJECTIVE:
To investigate the relationship between fetal lateral ventriculomegaly and chromosomal microarray analysis (CMA) abnormalities.METHODS:
Fifty fetuses with lateral ventriculomegaly detected by ultrasound and a normal karyotype were included. Forty four fetuses were classified as mild ventriculomegaly (MVM), in which the lateral ventricular atrium was 10-15 mm. Six had severe ventriculomegaly (SVM), with the lateral ventricularatrium being ≥ 15 mm. The fetuses were also divided into isolated (n= 21) and non-isolated groups (n= 29) based on whether they are associated with other anomalies.RESULTS:
Thirteen (26%) of the fetuses were found to be abnormal by CMA. For the 44 cases with MVM, 9 (20.9% ) were found to be abnormal, while for the 6 cases with SMV, 4 (66.7%) were found to be abnormal (P>0.05). CMA abnormalities were found in 2 (9.5%) of the 21 fetuses with isolated ventriculomegaly group and 11 (37.9%) of the 29 fetuses with non-isolated ventriculomegaly group (P<0.05).CONCLUSION:
Chromosome microdeletions and microduplications are the most common abnormalities found in fetal lateral ventriculomegaly. When ventriculomegaly is associated with other anomalies, the incidence of CMA abnormally is much higher. Prenatal diagnosis is necessary for fetuses with lateral ventriculomegaly.
