Balloon-assisted ultrasound-guided direct percutaneous embolization of a peripheral pseudoaneurysm with n-butyl cyanoacrylate.

We report the ultrasound-guided direct percutaneous injection of n-butyl cyanoacrylate to embolize an iatrogenic peripheral pseudoaneurysm secondary in a 33-year-old patient undergoing hemodialysis. We protected the parent artery with inflation of an angioplasty balloon across the neck during the cyanoacrylate injection. Complete occlusion of the pseudoaneurysm was achieved without ischemic complication.
