Arteriovenous fistulae and pseudoaneurysms are not rare after renal biopsy. The majority of these lesions (80%) are asymptomatic or show only transient symptoms. We present here a patient who developed life-threatening hematuria following an open renal biopsy. Arteriovenous fistula and pseudoaneurysm were detected in the biopsied kidney by color-coded Doppler sonography, confirmed by angiography, and the fistula was sealed by superselective arterial embolization with metallic coils. Color-coded Doppler sonography successfully detects the majority of arteriovenous fistulae after renal biopsy, and selective arterial embolization obviates the need for surgical intervention in most cases.
肾活检后动静脉瘘和假性动脉瘤并不少见。这些病变大多数（80%）无症状或仅表现为短暂症状。我们在此报告一名患者，其在开放性肾活检后出现危及生命的血尿。通过彩色编码多普勒超声在活检的肾脏中检测到动静脉瘘和假性动脉瘤，血管造影予以证实，并且通过用金属线圈进行超选择性动脉栓塞封闭了瘘管。彩色编码多普勒超声成功检测出肾活检后大多数动静脉瘘，并且在大多数情况下选择性动脉栓塞避免了手术干预的必要性。
