Objective: The purpose of this study is to evaluate the safety and efficacy of transarterial embolization for the treatment of symptomatic renal angiomyolipomas. Methods: All medical records of the patients who were presented with bleeding due to renal angiomyolipoma and received transarterial embolization at our department between September 2016 and December 2018 were reviewed. All of the feeding arteries were superselectively catheterized and microparticle embolization was performed. Microparticle and coil embolization was performed for active extravasation and pseudoaneurysm formation. Results: In the study period 14 angio myo lipomas (AML) in 13 consecutive symptomatic patients were embolized. The technical success rate was 100% with total embolization of all of the AMLs. 6 patients had acute retroperitoneal hemorrhage and procedures of these patients were performed in an emergency setting. All of the patients were discharged without symptoms, so clinical success rate was also 100%. No major complication nor mortality was observed. Median volume decrease was 42% (12%-76%) during the follow-up period. Conclusion: Treatment of symptomatic renal AMLs with selective transcatheter arterial embolization is safe, feasible and effective. Embolization of acutely ruptured AMLs with retroperitoneal hemorrhage using microparticles and coils can effectively stop bleeding.
