摘要
目的 探讨彩色多普勒超声诊断冠状动脉 心腔瘘的图像特征。方法 应用彩色多普勒超声的二维图像 ,多普勒频谱和彩色显像对 10例冠状动脉心腔瘘的多种解剖异常进行观察。结果 彩色多普勒诊断的共同特征是 :冠状动脉局部扩张 ,其中 7例为右冠状动脉增宽 ,1例为左冠状动脉主干增宽 ,2例为左冠状动脉回旋支增宽 ;心腔内出现异常相对高速度血流 ,为瘘管血流入心腔所造成 ,其中漏入左室 6例 ,入右室 2例 ,入右室流出道 1例 ,入冠状静脉 1例 ;右冠状动脉瘘管常沿右房室交界纡曲走行 ,左冠状动脉瘘管常沿左房室交界走行 ,局部可见瘘管的断面。介绍 2例合并较大动脉瘤的超声图像。结论 彩色多普勒超声诊断冠状动脉 心腔瘘具有很好的直观性和实用性。
Objective To study the view's feature of coronary artery fistulas by color Doppler echocardiography. Methods Ten cases of coronary artery fistulas were reported .The diagnosis was confirmed by 2 dimension, Doppler spectrum and color flow images. Results The echocardiography characteristics were : coronary artery enlarged, right n =7, left anterior decending n =1, circumflax blunch n =2. Turbulent flow shunting into the chamber was performed, shunting into left ventricle n =6, right ventricle n =2, right ventricular outflow tract n =1, coronary vein sinus n =1; Enlarged fistulous tube were seen. Two cases of congenital coronary artery fistula and aneurysm were reported. Conclusion Color Doppler echocardiography could provide directly and valuble information to diagnose coronary artery fistulas. [
