     运用彩色多普勒超声检查分析西藏高原地区先天性心脏病的特点 (pdf)

    [摘要] 目的 通过对高原地区青少年的先天性心脏病的普查,掌握先天性心脏病在高原地区的发病规律。方法 利用彩色多普勒超声检查,局部放大观察心脏各切面结构和彩色血流特征,必要时采用节段分析法。 结果 据统计分析,海拔越高,先天性心脏病的患病率越高。在各种先天性心脏病中,高原地区以动脉导管未闭(PDA)患病率最高,占患病总人数的47.17%。 结论 彩色多普勒超声检查是确诊先天性心脏病的有效快速的方法。西藏高原地区的缺氧导致的肺动脉高压可能促使先天性心脏病的患病率升高。

    [Abstract] Objective To discuss the characteristics among congenital heart diseases in Tibet by color Doppler sonography. Methods The characteristics of cardiac structures and color blood flow in 139 cases were observed with color Doppler sonography.The local amplification (zoom) and segmental analysis were used if necessary. Results The higher the altitude is,the more possibility to get congenital heart diseases.In Various congenital heart diseases,the incidence of PDA is the highest.The false positive rate was high in heart auscultation. Conclusion Because of its accuracy,speediness and economy,echocardiography is the security and guarantee of cardiovascular surgery in Tibet.The characteristics of congenital heart diseases in Tibet may be related to low oxygen content and high pulmonary arterial pressure. ......
