Endovascular therapeutic approach to peripheral aneurysms of the superior cerebellar artery

Peripheral aneurysms of the superior cerebellar artery may be difficult to treat surgically owing to their inaccessibility and to the frequent inability to preserve the involved parent artery. In fact, for most cases, surgical treatment consists of proximal parent artery occlusion and/or trapping with surgical clips. An equivalent endovascular therapeutic approach to these lesions may be an attractive alternative method of management. We describe two cases of peripheral superior cerebellar artery aneurysms that were treated successfully with endovascular embolization.
