Abstract:
Purpose To explore the ultrasound imaging characteristics and clinical significance of abnormal sylvian fissure in fetuses of transthalamic section at 22-26 weeks of gestation.Materials and Methods The ultrasound image characteristics,intracranial and extracranial malformations and clinical outcomes of 12 abnormal sylvian fissure cases of transthalamic section at 22-26 weeks of gestation in the Second Affiliated Hospital of Anhui Medical University from December 2018 to March 2022 were retrospectively analyzed.Results According to the ultrasound image characteristics of abnormal sylvian fissure,it could be divided into straight(4 cases)and shallow shapes(8 cases).The sylvian fissure of straight shapes was flat.Straight shapes were with 1 malformation of cortical development.The sylvian fissure of shallow shapes was corniform with unconspicuous insular platform.All of the shallow shapes were malformation of cortical development.Common intracranial abnormal signs mainly included other abnormal cerebral gyrus and sulcus(9 cases),ventricular dilatation or hydrocephalus(7 cases),partial or complete agenesis of corpus callosum(7 cases),etc.11 pregnant women chose to terminate their pregnancy,and 1 fetus died in the uterus after 5 days of ultrasound examination.Conclusion Fetal abnormal sylvian fissure at 22-26 weeks of gestation is an important clue to craniocerebral malformations,especially to malformation of cortical development.
