摘　　要：目的初步总结超声对36例合并肺动脉高压(PH)的先天性动脉导管未闭(PDA)的诊断经验。方法对疑诊合并PH的PDA患者进行超声心动图检测,应用二维、彩色及频谱多普勒超声重点观察肺动脉长轴分叉部及主动脉弓降部检测导管情况。结果超声对合并PH的PDA的诊断准确率为94.4%,2例漏诊。超声对PH的诊断率为97%,通过三尖瓣反流或(和)导管分流压差法估测重度PH15例,中度PH10例,轻度10例,1例轻度PH漏诊。结论先天性PDA合并重度PH可能发生漏诊,但多普勒超声心动图能提高本病的诊断率,并有助于评价PH程度,是目前最常用的、最有意义的影像学诊断方法。Objective To find out the diagnostic value and experience of ultrasound on the congenital patent ductus arterious （PDA） combined with pulmonary hypertension（PH）. Method 二维. CDFI and PW（CW） were performed on 36 patients of the suspected PDA ＋ PH, and the short axis of aorta view and short axis of pulmonary furcation view were carefully detected to examine the PDA. Results There is a high precise ratio about 94.4% on the diagnosis of the PDA ＋ PH patients with echocardiography. Mild PH （10） , moderate PH（10） and severe PH（15） were recorded by the regurgitation pressure gradient（PG） of tricuspid and the shunt PC, of PDA, 1 mild PH was missed with ultrasound. Conclusion It is a most common and valuable way to correctly diagnose the PDA together with PH with ultrasound, and the Doppler ultrasound is useful to improve the diagnostic rate.
