Intrarenal arteriovenous fistula (AVF) formation is a well-known complication of percutaneous needle biopsy, a procedure frequently performed following renal transplantation. Persisting AVFs are rare and most often formed within the first weeks to months following the provoking invasive procedure.
We present a case of a 66-year-old male transplant recipient with an intrarenal AVF which was discovered more than a decade after renal transplant and after the last invasive procedure was performed. The AVF become evolutive only another 6.5 years later, initially resulting in uncontrolled arterial hypertension, later followed by acute kidney injury. Transcatheter coil embolization was performed, leading to improvement in arterial hypertension and recovery of renal function to baseline levels.
Intrarenal AVFs can become evolutive and symptomatic long after the provoking procedure. Transcatheter coil embolization was technically and clinically successful.
肾内动静脉瘘（AVF）形成是经皮肾穿刺活检的一种已知并发症，肾移植后经常进行该操作。持续性AVF很少见，且大多在引发侵入性操作后的最初几周至几个月内形成。
我们报告一例66岁男性肾移植受者，其肾内AVF是在肾移植十多年后且在最后一次侵入性操作后才被发现。该AVF在另外6.5年后才开始发展，最初导致难以控制的动脉高血压，随后出现急性肾损伤。进行了经导管弹簧圈栓塞术，使动脉高血压得到改善，肾功能恢复到基线水平。
肾内AVF在引发操作后很长时间仍可发展并出现症状。经导管弹簧圈栓塞术在技术和临床方面均取得成功。
