Abstract

BACKGROUND: The prognosis of ischemic anterior circulation intracranial dissection (AC-ICD) is poor and its optimal management is still controversial. OBJECTIVE: To evaluate the safety and efficacy of a self-expanding stent for ischemic AC-ICD. METHODS: Eight patients (mean age, 36 years) underwent self-expanding stenting for ischemic AC-ICD. Imaging findings of ischemic AC-ICD, the reason for stenting, and the clinical and angiographic outcomes were retrospectively evaluated. RESULTS: AC-ICD involved intracranial internal carotid artery to middle cerebral artery (MCA) in 2, intracranial internal carotid artery alone in 3, and MCA alone in 3 patients. Six AC-ICDs showed complete or near occlusions while 2 had a severe degree of stenosis. Six AC-ICDs showed an intimal flap and 3 had intramural hematomas. Six patients underwent emergent stenting for acute stroke within 6 hours (n = 2) or crescendo-type stroke within 24 hours (n = 4), while 2 patients had stenting for recurrent ischemia on dual antiplatelet and/or anticoagulation after the initial attack. The mean dissectionrelated stenosis improved from 93.1% to 20.3% after stenting (P , .05). The mean National Institutes of Health Stroke Scale score improved from 7.5 to 1.4 (P , .05). All patients had excellent or favorable outcomes at 3 months: modified Rankin Scale score, 0 in 3, 1 in 3, and 2 in 1 patient(s). No patients had subarachnoid hemorrhage or ischemic symptom recurrence during the clinical follow-up (mean, 27 months). All stented arteries were patent without significant in-stent stenosis on angiographic follow-up (range, 3-12 months). CONCLUSION: Self-expanding stents seem to be safe and effective for AC-ICD presenting with acute/crescendo-type stroke or recurrent ischemia despite adequate medication.
