Intracranial arterial dissection is an important cause of stroke in young patients. Treatment options include observation, antiplatelet or anticoagulation regimens, and endovascular stent placement. The authors describe the case of a 14-year-old boy who presented with a symptomatic, posttraumatic dissection extending from the intracranial internal carotid artery to the middle cerebral artery. Images obtained approximately 48 hours after this incident revealed a subacute right frontal lobe infarct, and a CT stroke study (CT angiography and CT perfusion) confirmed the vascular injury and associated decreased perfusion, prompting revascularization with a self-expanding stent. The patient did well clinically after stent placement and showed no evidence of restenosis on follow-up angiography 3 and 6 months later. This report is, to the authors' knowledge, the first description of the use of a stent for a symptomatic intracranial dissection in an adolescent.
