OBJECTIVE : To assess the technical feasibility of treating ruptured pericallosal artery aneurysms with detachable coils and to evaluate the anatomic and clinical results.
METHODS : Over a period of 27 months, 12 patients with a ruptured pericallosal artery aneurysm were treated with detachable coils. A retrospective review was performed to assess the clinical and angiographic results. The three men and nine women had a mean age of 46.6 years (range, 35–75 yr). Seven patients presented in Hunt and Hess Grade II, three in Grade III, and two in Grade IV. Six patients had a concomitant intracerebral hematoma, and four had at least one additional aneurysm.
RESULTS : In all 12 patients, the pericallosal aneurysm could be reached with a microcatheter and the coils delivered. No procedure-related complications occurred. Angiography demonstrated that the initial occlusion was complete in 11 aneurysms and near-complete in 1. At follow-up angiography at 6 months, one aneurysm had become partially recanalized owing to coil compaction. At a mean clinical follow-up of 9.2 months, 11 patients had an excellent outcome and one patient had mild hemiparesis and aphasia.
CONCLUSION : Coiling of ruptured pericallosal artery aneurysms can be considered an alternative to surgical clipping.
