The antenatal ultrasonographic findings in a fetus with a left-sided congenital posterolateral diaphragmatic defect (CPLDD) are presented and discussed. Displacement of the heart towards the right and absence of a normally positioned fluid-filled stomach at repeated examinations are diagnostic. In the event of an intrathoracically displaced fetal stomach, which occurs in about 60% of the cases, a sonolucent area in the left chest may be found. In view of the dynamic nature of fetal stomach filling, more than one examination may be required to detect this feature. Antenatal recognition of congenital diaphragmatic hernia (CDH) has important consequences for perinatal management and can improve neonatal outcome.
本文展示并讨论了一名患有左侧先天性后外侧膈疝（CPLDD）胎儿的产前超声检查结果。多次检查发现心脏向右移位且未发现正常位置的充盈液体的胃，即可诊断。约60%的病例会出现胎儿胃向胸腔内移位，此时在左胸可能会发现一个无回声区。鉴于胎儿胃充盈的动态特性，可能需要进行不止一次检查才能发现这一特征。产前识别先天性膈疝（CDH）对围产期管理具有重要意义，并可改善新生儿结局。
