The types of abnormalities and clinical significance in fetus with non-isolated cerebral ventriculomegaly / 实用医学杂志

ABSTRACT

Objective To analysis the common abnormalities in fetus with ventriculomegaly and clinical significance. Methods Collected from March 2010 to December 2016,298 cases of pregnant women whose fetus with ventriculomegaly and accepted the prenatal diagnosis of pregnancy,including 109 cases of isolated cerebral ventriculomegaly(IVM),and 189 cases of non-isolated cerebral ventriculomegaly(NIVM).They were divided into mild groups(10.0-11.9 mm),moderate group(12.0-14.9 mm)and severe group(≥15.0 mm)according to the width of the lateral ventricle. Results(1)The most common abnormality of the NIVM were neurodevelopmental system(37.30%,94/252);The second was ultrasonic soft index(27.78%,70/252).(2)The most frequent combi-nation in mild group was ultrasonographic soft mark anomalies(44.76%,47/105),followed by other ultrasonic indi-cators(18.10%,19/105).The abnormal incidence of central nervous system was higher in middle group(45.16%, 42/93),followed by ultrasonic soft index abnormality(21.51%,20/93).The abnormality of the central nervous sys-tem was 62.96%(34/54)in severe group,followed by an abnormal(14.81%,8/54).(3)There was a difference in the nervous system and the ultrasonic-soft indicator between the non-isolated lateral ventricle dilation with different lateral ventricle widths(P<0.001).There was no difference in cardiovascular abnormalities. Conclusion Prena-tal ultrasound revealed that fetus with cerebral ventriculomegaly should carefully examine whether other abnormali-ties existed to determine the prognosis of the fetus and whether intervention should be taken.There was a difference between the different types of lateral ventricle and the prognosis.
