Abstract

Cerebral infarction is a major complication of intracranial artery angioplasty and stenting (IAS), and commonly affects the territory of the manipulated artery during IAS, resulting from distal embolization, vessel dissection, and acute vessel occlusion secondary to dissection or platelet aggregation. We present two cases with unexpected infarctions involving territories unrelated to the IAS procedures. We believe that blood pressure control under normal range may have triggered the adverse effects by hemodynamic infarction of other vascular territories with stenooclusive lesion.
