Reopening some occluded carotid arteries

Abstract

Intermittent ischemic symptomatology referable to a cerebral hemisphere was studied in 4 cases. Arteriography in each case showed complete occlusion of the ipsilateral internal carotid artery in the neck with collateral filling of the ipsilateral intracranial carotid artery into the cavernous portion. Endarterectomy was performed successfully in each case from 1-5 wk after the demonstrated complete occlusion. The collateral circulation to the intracranial portion of the internal carotid artery and the probable reasons for the technical success of these operations are discussed.
