Triple-balloon-assisted n-butyl-2-cyanoacrylate embolization of a cirsoid renal arteriovenous malformation.

We report a patient with a cirsoid renal arteriovenous malformation (AVM) causing massive hematuria that was successfully embolized by n-butyl-2-cyanoacrylate under triple-balloon occlusion. Proximal balloons were placed in the renal artery and vein for flow control, and a coaxial microballoon was placed in a feeding artery of the AVM to control the delivery of n-butyl-2-cyanoacrylate. Under triple-balloon occlusion, n-butyl-2-cyanoacrylate embolization achieved complete occlusion of the AVM with no procedure-related complications, such as renal infarction. This triple-balloon-assisted technique enabled us to control blood flow and the delivery of n-butyl-2-cyanoacrylate, allowing complete occlusion of the AVM. This approach may prevent proximal embolization and distal migration of n-butyl-2-cyanoacrylate.
