目的:探讨胎儿肺隔离症产前诊断的方法与意义及彩色多普勒超声检查的应用价值。方法:回顾性分析浙江大学医学院附属妇产科医院产前诊断ELS资料,总结其彩色多普勒超声表现及其诊断要点。结果:产前超声诊断ELS21例,病灶均为单侧。肿块直径1.0～3.5cm,首次检出时平均直径2.1cm;表现为强回声或偏强回声团块,内部回声均匀,肿块与周边组织分界清。11例肿块内探及来自主动脉的血供,6例来自于胸主动脉,5例来自于腹主动脉。结论:彩色多普勒超声检查是胎儿肺隔离症产前诊断的有效方法,对于肺隔离症的早期发现、早期诊断、早期治疗具有重要价值。
Objective: To investigate the method and significance of prenatal diagnosis of fetal pulmonary sequestration and the value of color Doppler ultrasonography. Methods: The data of prenatal diagnosis of ELS in Affiliated Obstetrics and Gynecology Hospital of Zhejiang University were retrospectively analyzed. The color Doppler ultrasound findings and diagnosis points were summarized. Results: Prenatal ultrasound diagnosis of ELS in 21 cases, lesions were unilateral. Mass diameter of 1.0 ~ 3.5cm, the average diameter of 2.1cm at the time of the first detection; performance of strong echo or strong echo mass, internal echo uniform mass and surrounding tissue demarcation. Eleven patients underwent exploration of the blood supply from the aorta, 6 from the thoracic aorta, and 5 from the abdominal aorta. Conclusion: Color Doppler ultrasonography is an effective method of prenatal diagnosis of fetal pulmonary sequestration. It is of great value for the early detection, early diagnosis and early treatment of pulmonary sequestration.
