Coil embolization of a large, wide-necked aneurysm using a double coil-delivered microcatheter technique in combination with a balloon-assisted technique.

The present paper describes a double coil-delivered microcatheter technique used in combination with a balloon-assisted technique to treat a patient with a large, wide-necked basilar tip aneurysm with detachable coil treatment. The aneurysm was completely occluded using this technique. There was no recanalization or any neurological deterioration within 12 months of embolization.
