Use of a mixture of Lipiodol and Cyanoacrylate in percutaneous embolization treatment of symptomatic renal Angiomyolipomas: Our experience

Purpose of this report is to describe safety and effectiveness of selective artery embolization in the treatment of bleeding angiomyolipomas (AMLs) of the kidney using a mixture of Lipiodol and Cyanoacrylate. Two patients with bleeding AMLs underwent to superselective embolization of the lesions using microcatheter and Lipiodol mixed with Cyanoacrylate in the ratio 3:1. Primary bleeding control rate was 100% with no major complications. Follow-up CT (mean time 18 months) demonstrated a significant reduction in size (about 50%) of the lesions. In conclusion, selective artery embolization with Lipiodol and Cyanoacrylate appear to be safe and effective in the treatment of bleeding AMLs.
