The diagnosis of a renal arteriovenous fistula is usually confirmed by angiography. Described is the utilization of color Doppler ultrasound to monitor a renal arteriovenous fistula before and after treatment by transcatheter steel coil embolization in a 63-year-old woman. Using color Doppler, the arteriovenous fistula with an aneurysmal lesion was clearly visualized. A pulsed-wave Doppler analysis showed increased flow velocity and decreased pulsatility in the supplying artery. After successful transcatheter occlusion of the fistula, these findings disappeared. The Doppler ultrasound technique is likely to be useful to detect and monitor a renal arteriovenous fistula noninvasively, simply, and quickly.
肾动静脉瘘的诊断通常通过血管造影来证实。本文描述了在一名63岁女性患者中，利用彩色多普勒超声监测经导管钢圈栓塞治疗前后的肾动静脉瘘。通过彩色多普勒，可以清晰地观察到伴有动脉瘤样病变的动静脉瘘。脉冲波多普勒分析显示供血动脉血流速度增加且搏动性降低。在成功经导管封堵瘘口后，这些表现消失。多普勒超声技术可能有助于无创、简单且快速地检测和监测肾动静脉瘘。
