目的探讨胎儿期肺动脉狭窄超声诊断的临床价值。方法对所有受检胎儿均进行四腔心切面及左右流出道切面扫查,并对发现的8例肺动脉狭窄的超声表现进行分析总结。结果产前超声诊断肺动脉狭窄8例,均经胎儿超声心动图复查,并引产证实,其中伴房间隔缺损3例,伴室间隔缺损2例。结论本结果显示胎儿产前超声行四腔心切面及左右流出道切面扫查对胎儿肺动脉狭窄具有重要的诊断与鉴别诊断价值,在孕18-24周进行产前超声有助于本病的早期诊断与处理。
Objective To investigate the clinical value of ultrasonic diagnosis of fetal pulmonary stenosis. Methods All the examined fetuses were examined by four-chamber echocardiography and left and right outflow tract sections. The ultrasound findings of 8 cases of pulmonary stenosis were analyzed and summarized. Results Prenatal ultrasound diagnosis of pulmonary stenosis in 8 cases, were confirmed by fetal echocardiography and induction of labor confirmed, of which 3 cases with atrial septal defect, ventricular septal defect in 2 cases. Conclusion The results show that fetus prenatal ultrasound four-chamber heart and left and right outflow tract scan of fetal pulmonary stenosis has important diagnostic and differential diagnosis of prenatal ultrasound during pregnancy 18-24 weeks contribute to the early Diagnosis and treatment.
