目的探讨胎儿隔离肺畸形产前超声特征及临床价值。方法对26例产前超声诊断为隔离肺畸形胎儿的超声声像图特征进行回顾性分析,并与产后病理及随访结果进行对比分析,26例均随访至引产或出生。结果 26例高度怀疑胎儿隔离肺孕妇中,其中病灶较大的9例选择终止妊娠,尸检病理诊断为隔离肺6例,另3例为先天性肺囊腺瘤Ⅲ型;其余病灶较小的17例均选择继续妊娠至出生,其中5例病灶密切随访逐渐缩小消失,余12例病灶大小变化不明显,胎儿出生后MRI诊断为隔离肺,未出现明显呼吸系统症状。产前超声诊断符合率为88.5%(23/26)。结论超声检查诊断胎儿隔离肺诊断率高,是产前早期发现胎儿隔离肺的首要检查方法。但肺囊腺瘤Ⅲ型易误诊为隔离肺,需注意鉴别。
Objective To investigate the characteristics and clinical value of prenatal ultrasound in fetal lung isolation. Methods 26 cases of prenatal ultrasound diagnosis of isolated lung malformations of fetal ultrasound sonographic features were retrospectively analyzed and compared with postpartum pathology and follow-up results were compared, 26 cases were followed up to abortion or birth. Results Of the 26 highly suspected pregnant women with fetal isolation, nine of the patients with larger lesions chose termination of pregnancy. The pathological diagnosis of autopsy was isolated pneumonia in 6 cases and the other 3 cases were congenital pulmonary cystadenoma type Ⅲ. The remaining 17 Cases were selected to continue pregnancy to birth, of which 5 cases close follow-up gradually reduced disappear, the size of the other 12 lesions did not change significantly, after birth MRI diagnosis of isolated lungs, no obvious respiratory symptoms. The coincidence rate of prenatal ultrasound was 88.5% (23/26). Conclusion Ultrasonography diagnosis of fetal isolation of lung diagnosis is high, is the first prenatal detection of fetal lung isolation the primary inspection method. However, cystadenoma type III is often misdiagnosed as isolated lung, need to pay attention to identification.
