Recently, ultrasound-guided percutaneous renal biopsy has been used in the diagnosis of renal diseases. Development of an arteriovenous fistula (AVF), which is one of the post-biopsy complications, is not frequently encountered. AVFs are usually asymptomatic; however, they may lead to serious outcomes. We report a 21-year-old patient, who had been on dialysis for 5 years. Due to high blood pressure (230/160 mmHg) and a thrill in the lumbar area detected on physical examination, Doppler examination was performed and a renal AVF was detected. Because the patient had a history of renal biopsy 5 years previously, the fistula was thought to be secondary to the biopsy. After embolization of the AVF, renal functions improved enough to terminate dialysis treatment.
最近，超声引导下经皮肾活检已用于肾脏疾病的诊断。动静脉瘘（AVF）是活检后的并发症之一，并不常见。AVF 通常无症状，但可能导致严重后果。我们报告了一名 21 岁的患者，他已经透析 5 年了。由于体格检查时发现高血压（230/160mmHg）和腰部震颤，进行了多普勒检查，发现了一个肾动静脉瘘。由于该患者 5 年前有肾活检史，因此认为瘘管是由活检引起的。动静脉瘘栓塞后，肾功能改善足以终止透析治疗。
