Therapy of carotid stenosis in contralateral occlusion of the internal carotid artery

From January 1985 up to December 1987 sixteen patients with unilateral stenosis of the internal carotid artery (ICA) and concomitant chronic contralateral carotid occlusion underwent surgical correction of the stenosis. 31.2% were asymptomatic, 18.7% had transient ischemic attacks and 50% had suffered a stroke. On the occluded side 31.2% had had a stroke. Angiography showed intracerebral shunting to the occluded side in 43.7%; 56.2% of the patients had concomitant stenoses of intrecerebral vessels
