彩色多普勒血流显像对成人亚临床型房间隔缺损的诊断价值

目的　评价彩色多普勒血流显像对成人亚临床型房间隔缺损的诊断价值。方法　对 12 2例经彩色多普勒血流显像检查首先诊断的成人亚临床型房间隔缺损进行回顾分析。结果　此组病例年龄较大 ,女性居多 ,无特异性的症状和体征 ,经彩色多普勒血流显像检查均显示不同程度房水平左向右分流。结论　彩色多普勒血流显像是诊断亚临床型房间隔缺损的非侵入性首选技术

Diagnostic Value of Color Doppler Flow Imaging in Subclinical Atrial Septal Defects

Objective To evaluate the usefuluness of the color Doppler flow imaging(CDFI) in subclinical atrial septal defects(ASD).Methods We reviewed 122 cases of subclinical ASD in adult which were first detected with CDFI.Results We found most of the patients were women and elder people,and no more special clinical symptoms and signs can be found.Color Doppler flow imaging had characteristic abnomallities making the dosis of ASD possible and easily with a high degree of accuracy in patients in whom the clinical presentation was atypical different magnitudes of left-to-right shunt were revealed in all these patients.Conclusion CDFI is a good noninvasive technique in the diagnosis of subclinical atrial septal defects.
