Abstract:
Fetal seizure is rarely observed. Investigation of both video-recording of seizures and cardiotocography is crucial for a precise diagnosis. Here, we report a case of fetal seizure, and also show a video-ultrasound recording. A 40-year-old woman was admitted to us due to loss of variability in cardiotocography. Ultrasound repeatedly revealed opisthotonus-like and clonic-seizure-like movements. After the abnormal movement, tachycardia up to 210 bpm (postictal tachycardia) was noted. Ultrasound revealed a nuchal cord. A careful investigation of video-ultrasound recording by an epilepsy specialist led to the confirmation of epileptic seizures. At 364/7 , she vaginally gave birth to an infant with an umbilical artery pH of 7.22. The infant died 30 min after birth. No clear video-recordings associated with fetal seizure were available for cases reported so far in the literature. The video provided in this case may be of use for further analyses.
