Abstract：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．
