The Society for Maternal-Fetal Medicine released a statement on the use of ultrasound screening for fetal microcephaly following Zika virus exposure.
Microcephaly is a condition in which the size of the head is smaller than expected for age. This condition in fetuses and infants has been associated with the recent outbreak of Zika virus. Due to this association, the Centers for Disease Control and Prevention, American Congress of Obstetricians and Gynecologists and the Society for Maternal-Fetal Medicine have suggested ultrasound evaluation to measure the baby's head in pregnant women who have been infected or potentially exposed. Diagnosis of microcephaly by ultrasound is not always straightforward and can be complex. The Society for Maternal-Fetal Medicine provided recommendations on how to interpret the findings, including when to perform follow up ultrasound, as well as a table of values at each week of pregnancy that would define the lower limit of normal. The goal is to provide the tools to health care providers to counsel women who may have been exposed to the Zika virus. The Society for Maternal-Fetal will continue to assist clinicians in tackling this new health threat.
