经动脉栓塞治疗肾动静脉畸形或瘘所致血尿

Transarterial embolization for hematuria caused by renal arteriovenous malformations or fistulae

目的评价经动脉栓塞治疗肾动静畸形(或瘘)所致血尿的安全性和疗效。方法回顾性分析因肉眼血尿行肾动脉造影而确诊的肾血管病变7例,包括先天性肾动静脉畸形3例,非肿瘤获得性动静脉瘘4例,选择相应的栓塞剂行动脉栓塞治疗。结果7例均获成功栓塞,术后1～7d临床肉眼血尿症状完全消失,无严重并发症,随访l2～36个月无再发。结论经动脉栓塞治疗肾动静脉畸形或瘘所致的血尿安全、有效。

Objective To evaluate the efficacy and safety of transarterial embolization for hematuria caused by renal arteriovenous malformation or fistulae. Methods Seven patients with gross hematuria caused by renal arterial abnormalities were retrospectively reviewed, of which three had congenital renal arteriovenous malformations and the other four had non-neoplastic acquired renal arteriovenous fistulae, All patients were confirmed by renal arterial angiography and undergone embolization with various embolic materials. Results Embolization was successfully carried out in all cases. Gross hematuria disappeared one to seven days after the procedure. No severe complications were encountered. No recurrence occurred within 12 to 36 months of follow- up, Conclusions Transarterial embolization is safe and effective for hematuria caused by renal arteriovenous malformations or fistulae.
