超声心动图对冠状动脉瘘的诊断价值

Color doppler echocardiography in diagnosis of coronary artery fistula

目的:探讨超声心动图在冠状动脉瘘诊断中的方法与临床应用价值。方法:应用彩色多普勒超声诊断仪对111例超声诊断的冠状动脉瘘部位、数目、血流动力学状态进行回顾性分析。结果:57%冠状动脉不同程度增宽并迂曲走行,频谱多普勒呈特征性改变。瘘入右房6例,瘘入右室24例,瘘入左室6例,瘘入肺动脉75例,其中微小冠状动脉-肺动脉瘘48例随诊中,余均经CT及造影证实,漏诊1例,误诊3例。56例伴有法乐氏四联症、房间隔缺损、室间隔缺损、心肌致密化不全等其他畸形。结论:彩色多普勒超声心动图诊断冠状动脉瘘无创、快捷、准确,可作为首选影像学检查方法,为临床提供丰富资料。

Objective：To evaluate the clinical value of color doppler echocardiography in diagnosis of coronary artery fistula.Method：In a retrospective analysis,we observed the lesion site,number and blood flow state of coronary artery fistula using color doppler echocardiography in 111 cases.Result：The 57% coronary artery of them widened in different level and circuitous.Coronary artery fistula were located in the right atria in 6 cases,right ventricular in 24 cases,in left ventricle in 6 cases,in pulmonary artery in 75 cases.The 48 cases of the latter 75 cases were small coronary pulmonary fistula,and still were followed-up.They all were confimed by computed tomography（CT）and angiography.One case was escape diagnosis and 3 patients were misdiagnozed.Conclusion：Color doppler echocardiography is noninvasive,rapid and accurate in the diagnosis of coronary artery fistula,and can be used as the prefer method in imaging examination.
