Stroke associated with carotid endarterectomy.
Between 1966 and 1976, eleven strokes occurred in association with 509 carotid endarterectomies performed at Walter Reed Army Medical Center. Contralateral carotid arterial occlusion with unilateral stenosis, bilateral carotid stenoses, or multiple extracranial (with or without intracranial) stenoses were present in all patients in whom stroke developed. Preventable technical factors contributing to or directly causing stroke were identifiable in six of the eleven patients. Better appreciation of the high risks associated with the above arteriographic patterns and elimination of technical mishaps should lead to an improvement in our already respectably low stroke rate of 2.2 per cent.
