The second patient presented with a long history of seizures and a small intracerebral hemorrhage.

Under flow arrest, Onyx was injected via the microcatheter with excellent nidal penetration. In both cases, there was complete angiographic obliteration of the treated component of the AVM.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Onyx embolization under balloon catheter flow arrest allows for greater nidal penetration of embolic material and improved reflux control.
