Transcatheter arterial embolization with n-butyl 2-cyanoacrylate (hystoacryl) for renal arteriovenous malformation: case report

A 22-year-old woman presented with sudden onset gross hematuria. Drip infusion pyelography and enhanced computerized tomography yielded no unusual findings. Renal angiography demonstrated an arteriovenous malformation (AVM) in the central portion of the right kidney. Superselective transcatheter arterial embolization (TAE) of the AVM was performed with a steel coil, and hematuria disappeared after TAE. However, severe gross hematuria developed again six days later. Second renal arteriography revealed the formation of the collateral vessels. By using n-butyl 2-cyanoacrylate (NBCA), TAE for AVM was performed successfully. She has been free of hematuria during the one-year follow-up.
