Revascularization for Anterior Cerebral Artery Dissecting Aneurysms : Three Case Reports

概要

We describe three rare cases of dissecting aneurysms in the anterior cerebral artery (ACA) treated by surgical reconstruction, and reviewed 79 previously reported cases with the ACA dissecting aneurysm. We found that 35 (77.8%) of 45 patients with ischemic event and 15 (40.5%) of 37 patients with hemorrhagic event were treated conservatively, with 11.4% (4/35 cases) and 13.3% (2/15) risk of bleeding and rebleeding, respectively. Furthermore, half of these patients died. The other 32 patients were treated surgically, and their outcome was favorable, especially after surgical reconstruction. Simultaneous treatment of both hemorrhagic and ischemic events is essential. We recommend early treatment with revascularization for patients with ACA dissection that has hemorrhaged and for patients presenting with signs of clinical deterioration with ischemic event.
