Arteriovenous (AV) fistulas are an uncommon but well-known complication of percutaneous renal biopsies. Recent studies suggest that Color Doppler Sonography is useful in the identification of post-biopsy renal AV fistulas. AV fistulas may cause persistent hematuria, hypertension, or high-output cardiac failure. In these cases surgical ligation or angiographic embolization is necessary. In this study we report a case of post-biopsy renal AV fistula identified with Color Doppler Sonography and Angiography. The renal AV fistula also was embolized with a platinum microcoil under angiographic and ultrasonographic guidance.
动静脉（AV）瘘是经皮肾活检一种罕见但广为人知的并发症。近期研究表明，彩色多普勒超声有助于识别活检后肾动静脉瘘。动静脉瘘可能导致持续性血尿、高血压或高输出量心力衰竭。在这些情况下，手术结扎或血管造影栓塞是必要的。在本研究中，我们报告了一例经彩色多普勒超声和血管造影确诊的活检后肾动静脉瘘病例。该肾动静脉瘘也在血管造影和超声引导下用铂微线圈进行了栓塞。
