Unilateral normal perfusion pressure breakthrough after carotid endarterectomy: case report.
The authors report a case of unilateral malignant cerebral edema that occurred after the removal of a high grade atheromatous lesion of the ipsilateral internal carotid artery. A form of unilateral normal perfusion pressure breakthrough caused by postischemic impairment of cerebrovascular autoregulation and exacerbated by systemic hypertension is thought to have contributed to this complication. Control of the hypertension and treatment of the cerebral edema with mannitol and dexamethasone led to a complete neurological recovery.
