【摘要】 目的　对法洛四联症患者应用超声测量肺动脉、主动脉与左室舒张期内径 ,借以判断肺动脉发育情况 ,估计手术效果。方法　取左室长轴切面测量主动脉内径 ,左室舒张期内径 ,观测两者比值 (AoD/LVDd)与主动脉骑跨、室间隔缺损、肺动脉瓣狭窄或伴右室流出道狭窄的关系 (RVOS)。结果　 70例手术对照病例中 ,主动脉宽度与左室舒张期内径成反比例 ,与主动脉骑跨程度、肺动脉瓣狭窄或伴右室流出道狭窄成正比例。左室舒张期内径与手术效果成正相关。结论　测量主动脉与左室舒张期内径比值 ,是判断肺动脉发育情况、法洛四联症严重程度、手术效果的一种简单有效的方法更多还原

【Abstract】 Objective To evaluate the role of measuring the aortic diameter (AoD) and left ventricular end diastolic diameter (LVDd) in tetralogy of Fallot patients with echocardiography. Methods Measuring the AoD and LVDd, observing the relations between the ratio (AoD/LVDd) and ventricular septal defect (VSD), aortic overriding ventricular septum, pulmonary stenosis (PS) and right ventricular outlet stenosis (RVOS). Results It demonstrated that AoD is an inverse proportion to LVDd, and in proportion to the degree of aortic overriding ventricular septum and pulmonary stenosis. It also revealed that LVDd could predict the efficacy of operation. Conclusion AoD/LVDd is a simple but effective method to assess the development of pulmonary artery and the degree of F4.更多还原
