Subamniotic hemorrhage, a rare condition involving bleeding between the amniotic membrane and fetal chorionic plate, presents diagnostic challenges.
A 35-year-old woman at 37 weeks of gestation who presented with lower abdominal discomfort and decreased fetal movements came to our emergency department. Ultrasound revealed medium-strong echoes in the amniotic fluid and inhomogeneous echoes around the umbilical cord. A Category II fetal heart rate baseline (FHR) tracing, indicative of fetal compromise, along with an elevated MCA-PSV approaching the diagnostic threshold for fetal anemia, suggested ongoing fetal hypoxia or hemorrhage and warranted immediate delivery to mitigate the risk of adverse outcomes. An emergency cesarean section revealed significant intraamniotic hemorrhage and a subamniotic hematoma near the umbilical cord insertion.
This case highlights the importance of considering rare etiologies for common symptoms and underscores the value of timely ultrasonography and decisive intervention in preventing adverse fetal outcomes.
羊膜下出血是一种罕见的情况,涉及羊膜和胎儿绒毛膜板之间的出血,带来了诊断挑战。
一名37周妊娠的35岁女性因下腹部不适和胎动减少前来我院急诊科。超声显示羊水中有中等强度回声,脐带周围回声不均匀。II类胎儿心率基线(FHR)描记图提示胎儿窘迫,同时大脑中动脉收缩期峰值速度(MCA-PSV)升高接近胎儿贫血的诊断阈值,提示胎儿持续缺氧或出血,需要立即分娩以降低不良后果的风险。急诊剖宫产显示羊膜腔内有大量出血,脐带插入处附近有羊膜下血肿。
本病例强调了考虑常见症状的罕见病因的重要性,并强调了及时超声检查和果断干预在预防不良胎儿结局方面的价值。
