Double microcatheter technique for detachable coil treatment of large, wide-necked intracranial aneurysms

BW Baxter, D Rosso and SP Lownie

We describe a technique used to treat two patients with large, wide- necked aneurysms during the past 2 years. In the initial attempts at embolization, evidence of coil instability within the aneurysm or significant impingement of coil loops on the parent artery was observed. Advancement of a second microcatheter into the aneurysm allowed two coils to be braced across the aneurysmal neck before the detachment of either coil. This technique permitted successful coil treatment in both patients.
