室间隔完整的肺动脉闭锁彩色多普勒超声心动图特征及规律性研究

Characteristics and regularity of color Doppler echocardiography of pulmonary atresia with intact ventricular septum

目的探讨室间隔完整的肺动脉闭锁彩色多普勒超声心动图特征及规律性。方法选取2013年12月~2015年8月我院收治的40例室间隔完整的肺动脉闭锁患者,分析患者彩色多普勒超声心动图特征及规律性。结果 40例室间隔完整的肺动脉闭锁患者采用彩色多普勒超声心动图进行诊断,诊断的准确率为95.0%（38/40）。其余2例患者分别误诊为重症法洛三联症以及孤立性左心室发育不全。在二维超声心动图的帮助下,对患者心尖四腔心切面进行检查中,所有患者均显示为2个心房正位,并且患者2组房室瓣分别开向2个心室腔。其中有26例患者显示右心室内径增大现象,12例患者合并三尖瓣狭窄显示其三尖瓣出现不同程度的开发受限,2例患者合并房间隔膨出瘤并显示其房间隔向左心房膨出。结论室间隔完整的肺动脉闭在彩色多普勒超声心动图检测下具有较为明显的特征和规律性,但需要鉴别开来重症法洛三联症以及孤立性左心室发育不全。

Objective To explore the characteristics and regularity of color Doppler echocardiography in pulmonary atresia with ventricular septal integrity. Methods 40 cases of patients with pulmonary atresia with intact ventricular septum were selected in our hospital from December 2013 to August-2015. The characteristics and regularity of color Doppler echocardiography were analyzed. Results 40 cases of ventricular septal complete pulmonary artery occlusion using color Doppler echocardiography for diagnosis, the accuracy rate of diagnosis was 95%（38/40）. The remaining 2 patients were misdiagnosed as severe tetralogy of Fallot and isolated left ventricular hypoplasia. With the help of the two-dimensional echocardiography, four patients with apical chamber heart were examined, and all patients were shown to have a positive position of 2, and 2 groups of patients with atrioventricular valve were opened to 2 ventricle. Including 26 patients showed right ventricular diameter increase, 12 cases of patients with tricuspid stenosis display third cusps appear different degree of development limited, 2 patients with atrial septal aneurysm and display the room bulging of left atrial septum. Conclusion Ventricular septum complete pulmonary artery closed in color Doppler ultrasound echocardiography examination has obvious characteristic and regularity, but need to distinguish severe tetralogy of Fallot and isolated left ventricular hypoplasia.
