Our objective was to assess the prevalence and history of arteriovenous fistula after renal biopsy in pediatric patients by the use of color Doppler sonography. Fifty patients, aged 6 days to 18.5 years, underwent sonographically guided renal biopsy. Color Doppler sonography was performed prior to, during, and after the procedure. Postbiopsy hematoma was detected in 46 patients (92%), of whom 10 suffered clinically significant bleeds. Six patients (age range, 8 to 18.5 years) developed postbiopsy arteriovenous fistula. In three cases the arteriovenous fistula diminished spontaneously, one persisted without symptoms, and two symptomatic arteriovenous fistulas needed coil implantation. Color Doppler sonography demonstrated all arteriovenous fistulas 4 hours after the procedure and duplex Doppler sonography demonstrated the flow disturbances in the feeding and draining vessels. We conclude that color Doppler sonography allows noninvasive detection and follow-up study of postbiopsy arteriovenous fistula, thus helping to define management after interventional procedures.
我们的目的是通过彩色多普勒超声评估儿科患者肾活检后动静脉瘘的发生率及病史。50例年龄在6天至18.5岁的患者接受了超声引导下的肾活检。在操作前、操作期间及操作后均进行了彩色多普勒超声检查。46例患者（92%）检测到活检后血肿，其中10例发生了具有临床意义的出血。6例患者（年龄范围8至18.5岁）发生了活检后动静脉瘘。3例动静脉瘘自发消失，1例持续存在但无症状，2例有症状的动静脉瘘需要进行弹簧圈植入。彩色多普勒超声在操作后4小时显示了所有动静脉瘘，双功多普勒超声显示了供血和引流血管中的血流紊乱。我们得出结论，彩色多普勒超声能够对活检后动静脉瘘进行无创检测及随访研究，从而有助于确定介入操作后的处理方法。
