[目的]探讨彩色多普勒显像(CDFI)技术诊断冠状动脉瘘的应用价值和临床意义。[方法]采用彩色多普勒显像技术,通过多个切面显示扩张的冠状动脉并仔细观察,寻找其在心腔的瘘口,研究图像特征及规律性。[结果]冠状动脉扩张显著、瘘口处环状无回声区,心腔或肺动脉瘘内彩色多普勒血流显像显示异常血流束信号。13例冠状动脉瘘中,左冠状动脉瘘3例(25%),右冠状动脉瘘10例(76.9%)。多数为右冠状动脉瘘,少数为左冠状动脉瘘。合并室间隔缺损1例,主动脉瓣关闭不全1例。[结论]彩色多普勒显像对冠状动脉瘘的图像特征和规律性诊断是有一定价值。
[Objective] To explore the value and clinical significance of color Doppler imaging (CDFI) in the diagnosis of coronary artery fistula. [Methods] With color Doppler imaging technique, the dilated coronary arteries were displayed through multiple sections and carefully observed to find the fistula in the cardiac cavity. The image characteristics and regularity were studied. [Result] The coronary artery was obviously dilated. The annular aneurysm area, intracardiac or pulmonary fistula internal color Doppler flow imaging showed the abnormal blood flow signal. Thirteen cases of coronary fistula, left coronary artery fistula in 3 cases (25%), right coronary artery fistula in 10 cases (76.9%). Most of the right coronary fistula, a few left coronary fistula. 1 cases of combined ventricular septal defect, aortic valve insufficiency in 1 case. [Conclusion] Color Doppler imaging is of certain value in the diagnosis of coronary artery fistulas.
