HERNANDEZ S, Mercedes et al. Detección ecográfica y pronóstico de la ventriculomegalia fetal. Rev. chil. obstet. ginecol. [online]. 2012, vol.77, n.4, pp.249-254. ISSN 0717-7526. http://dx.doi.org/10.4067/S0717-75262012000400002.
Background: Fetal ventriculomegaly is the most sensitive sonographic sign for central nervous system anomalies. Neonatal morbidity and mortality depends on the etiology of the ventriculomegaly and the presence of other malformations. Isolated non-progressive ventriculomegaly is associated with 70% favorable results, with a great disparity among studies. Aims: To establish the relationships between ventriculomegaly and perinatal outcome. Methods: The authors reviewed 60 cases of prenatally diagnosed fetal ventriculomegaly in the Canary Islands University Hospital. An ultrasonographic measurement of the lateral ventricles of 10 mm or more was considered as ventriculomegaly. Fetal and maternal serology was performed as well as fetal karyotyping. Results: 23 patients decided to terminate the pregnancy due to unfavorable prognosis. In 28 cases outcome was favorable. 70% of isolated ventriculomegaly corresponded to healthy newborns. 10% of the fetuses had aneuploidies. Conclusion: Prognosis is favorable if ventriculomegaly is isolated and non-progressive. Measurement of the lateral ventricle does not predict outcome. Disparity of results in literature makes it necessary for each Hospital to rely on their own data and guidelines to assess parents on the fate of the pregnancy.
