目的:探讨胎儿隔离肺的产前超声表现,评价其转归及预后。方法:对2例在产前超声筛查中诊断为隔离肺的声像图特征进行分析,观察双侧肺部回声,有无异常病灶,并用CDFI显示病灶血供来源。结果:2例诊断胎儿隔离肺孕妇中,1例合并并发症选择终止妊娠;1例选择继续妊娠,胎儿出生后MRI诊断为隔离肺,至今未出现呼吸系统症状。结论:产前超声可以较准确地诊断胎儿隔离肺,未合并其他畸形的单纯隔离肺胎儿预后较好。
OBJECTIVE: To investigate the prenatal ultrasound findings of fetal isolated lung and to evaluate its outcome and prognosis. Methods: The echographic features of 2 isolated pulmonary cases diagnosed in prenatal ultrasound screening were analyzed. The bilateral pulmonary echoes were observed with or without abnormal lesions and CDFI was used to show the source of the lesions. Results: In 2 cases of pregnant women diagnosed with fetal isolation, one patient with complicated complications chose termination of pregnancy. One patient chose to continue with pregnancy. MRI of the fetus after birth was isolated from the lungs and so far no respiratory symptoms occurred. Conclusion: Prenatal ultrasound can be more accurate diagnosis of fetal lung isolation, without other malformations isolated isolation of fetal lung good prognosis.
