Endovascular stenting of a traumatic dissecting aneurysm of the extracranial internal carotid artery--case report.

A 57-year-old male presented with a traumatic dissecting aneurysm of the distal, extracranial internal carotid artery (ICA). Stent placement resulted in complete occlusion of the aneurysm and preservation of the carotid blood flow. He also had an atherosclerotic stenosis of the ipsilateral middle cerebral artery, which was uneventfully treated by angioplasty 3 months after stent placement. Endovascular reconstruction of the ICA with a stent may be the best way to occlude dissecting aneurysms, especially in patients who cannot tolerate ICA occlusion, are at risk from delayed ischemia, or have wide-necked or multiple aneurysms.
