【摘要】 目的 :超声测量法洛四联症患者主动脉、左室舒张末期内径 ,计算其比值 ,估测手术效果。方法 :取左室长轴切面测量主动脉内径、左室舒张末期内径 ,计算两者比值 ,分析其与主动脉骑跨率、室间隔缺损、肺动脉瓣狭窄或伴右室流出道狭窄的关系 ,并与手术结果相对照。结果 :70例手术病例均行彩超检查 ,研究结果表明 :主动脉越宽 ,左室舒张末期内径越小 ,且两者比值越大 ,主动脉骑跨率越大 ,肺动脉瓣狭窄或伴右室流出道狭窄越严重 ,手术效果越差。结论 :测量主动脉与左室舒张末期内径比值 ,是判断肺动脉发育情况、估计法洛四联症严重程度、预测手术效果的一种简单有效的方法。更多还原

【Abstract】 Objectives: To predict the operative effect of Fallot′s tetralogy (F4) by the ratio of aortic diameter (AoD) and left ventricular end diastolic diameter (LVDd). Methods: The relation of AoD/LVDd, measured by echocardiography in left ventricular long axis, and aortic overriding ventricular septum, ventricular septal defect (VSD), pulmonary stenosis (PS), right ventricular outlet stenosis (RVOS) and the operative effect were analyzed respectively in 70 patients with F4. Results: The larger AoD was, the smaller LVDd was. The larger AoD/LVDd were, the more serious of the degree of aortic overriding ventricular septum, PS and/or RVOS were, and the worse the operative effects were. Conclusions: AoD/LVDd is a simple and effective index to assess the degree of PS and F4, and to predict the operative effect of F4.更多还原
