Color flow image-directed Doppler ultrasound was used to image 9 iatrogenic arteriovenous (AV) fistulas in the groin following femoral artery catheterization. Characteristic findings in the color images and spectral waveforms seen in most patients included (1) visible connection between the artery and vein (8 cases); (2) a multicolored speckled mass at the fistula site (7 cases); (3) spreading of color pixels into the extraluminal soft tissues (7 cases); (4) high diastolic flow in the arterial waveform proximal to the fistula site (7 cases); (5) decreased flow in the artery caudal to the fistula (5 cases); and (6) high velocity turbulent flow, sometimes with a pulsatile component, in the vein near the fistula (9 cases). The authors conclude that color flow imaging is useful in differentiating an AV fistula from other complications of femoral artery catheterization, such as pseudoaneurysm or hematoma.
采用彩色血流成像引导的多普勒超声对9例股动脉插管后腹股沟区医源性动静脉（AV）瘘进行成像。大多数患者彩色图像和频谱波形的特征性表现包括：（1）动脉与静脉之间可见连接（8例）；（2）瘘口处有多彩斑点状团块（7例）；（3）彩色像素扩散至管腔外软组织（7例）；（4）瘘口近端动脉波形舒张期血流增高（7例）；（5）瘘口尾侧动脉血流减少（5例）；（6）瘘口附近静脉内高速湍流，有时伴有搏动成分（9例）。作者得出结论，彩色血流成像有助于将AV瘘与股动脉插管的其他并发症，如假性动脉瘤或血肿相鉴别。
