Surgery of the internal carotid artery and the extracranial vertebral artery is of a fundamentally preventive nature, and justifiable when intra and postoperative complications (intraoperative stroke, postoperative vessel occlusion, postoperative TIA and/or stroke) remain within very low limits (less than 5% according to major case-series'). To minimize damage to the arterial wall that could cause vessel occlusion and even neurological damage, the authors propose the use of intracranial aneurysm clips for temporary closure of the neck vessels, explaining the methods used for selection of these clips.
