Early stroke occurs in 0.9% to 7% of patients undergoing carotid endarterectomy (CEA). These have been thought to be mostly due to embolization. However, in our recent clinical experience, we noted hyperperfusion syndrome to be a significant cause of postoperative strokes. Therefore, we reviewed our experience and investigated the distribution of causes of early postoperative strokes. ⋯ Embolization to the cerebral arteries remains the leading cause of early postoperative strokes. However, hyperperfusion syndrome also accounts for a significant portion of these postoperative strokes. The percentage of patients with this syndrome might be even higher, once clinical picture is clearly defined. These data warrant further investigation of hyperperfusion syndrome.
