超选择性肾动脉栓塞治疗肾动静脉畸形所致血尿

Superselective arterial embolization for hematuria caused by renal arteriovenous malformations

目的：评价经动脉栓塞治疗静脉曲张型肾动静畸形（ravM）所致血尿的安全性和疗效。方法：回顾性分析10例因肉眼血尿为主要表现的rAVM患者，随访观察行微钢圈栓塞治疗的效果及安全性。结果：10例经DSA检查后均诊断为静脉曲张型rAVM，均获得成功栓塞，术后15-48h（平均28h）血尿消失，随访12-36月未见血尿复发，无严重并发症。结论：经动脉微钢圈栓塞治疗静脉曲张型rAVM所致的血尿安全、有效。

Objective： To investigate the therapeutic effect and safety of transarterial embolization in renal arteriovenous malformation （rAVM）. Methods： Superselective transarterial embolization （TAE） were performed in 10 cases with rAVM causing gross hematuria their effect and safety were analyzed retrospectively. They were followed up for 12 to 36 months （mean 23.8 months） after the procedure. Results： All cases were diagnosed as cirsoid rAVM after renal artery DSA. Superselective TAE with micro coils after DSA was performed successfully in all patients. Hematuria disappeared in 15 to 48 hours （mean 28 hours） after TAE. No severe complications were encountered. No recurrence occurred within 12 to 36 months of follow-up. Conclusions： Transarterial embolization with micro coils is safe and effective for hematuria caused by cirsoid renal arteriovenous malformations.
