Perforator infarction accompanying intracranial atherosclerosis is usually explained by the obstruction of perforator by atheroma of the parent artery. However, the improvement of neurologic symptom after stenting is hardly explained by the concept. Here, we report a case of perforator infarction caused by the unique hemodynamic condition of the poststenotic ...
