目的探讨胎儿肺缺如的声像图特点,提高对肺缺如疾病的认识,减少漏诊及误诊。方法回顾性分析3例胎儿右肺缺如并合并其他畸形的超声影像资料及与引产后尸检结果对照。结果超声图像特点为胎儿右侧胸腔内未见肺组织影像,左肺增大,心脏向右移位。彩色多普勒未见右肺动脉及静脉,仅见左侧肺动脉。结论超声检查对胎儿肺缺如的诊断具有很高临床应用价值,可以在中晚期妊娠进行诊断。
Objective To explore the characteristics of fetal lung lack of sonography to improve the understanding of lung disease, reduce the missed diagnosis and misdiagnosis. Methods A retrospective analysis of 3 cases of fetal right lung absent and combined with other deformities ultrasound imaging data and post-induction of autopsy results. Results Ultrasound images were characterized by no lung tissue image in the right chest of the fetus, left lung enlargement, and right heart displacement.
