Results of endovascular management for mid-basilar artery aneurysms.
We evaluated the results of endovascular management of patients with mid-basilar artery aneurysm (mBAA). During a seven year period, 14 patients (mean age 39.6 years, male/female ratio 1:1) with mBAA were treated with endovascular techniques at our institute. Pretreatment clinical grades were determined using the Hunt-Hess scale. Outcome was evaluated using the Glasgow Outcome Scale scores (GOS) during a mean follow-up period of 15.6 months (range, three to 70 months). Fourteen patients with 15 mBAAs were treated endovascularly. Four (28.6%) patients died of rebleeding within one day after embolization. In ten mBAAs, immediate postprocedural angiograms showed that complete occlusion was achieved, subtotal occlusion in one, and incomplete occlusion in four. Follow-up angiographic results in ten patients confirmed complete occlusion of 11 aneurysms. Long-term outcome was good (GOS Score 4 or 5) in ten patients (71.4%) and fatal (GOS Score 1) in four (28.6%). Favorable overall long-term outcome can be achieved in 78.6% patients with mBAAs. Endovascular management of mBAAs is an effective treatment in the long-term. In our experience, the natural history of mBAAs is dismal.
