Abstract:
The combination of surgical and endovascular treatment for complex intracranial aneurysms has previously been used in a staged fashion. To perfect the clipping process of a complex anterior communicating artery aneurysm and to avoid a second staged procedure, the authors used a method of direct intraoperative transaneurysmal coil-assisted clip occlusion of the aneurysm. To the authors' knowledge this is the first time direct intraoperative transaneurysmal coil-assisted clip occlusion has been reported. It should be kept in mind as one of the options to help in complete obliteration of complex intracranial aneurysms.
