Assessment by fluorescein angiography of surgical treatment of occlusive carotid artery disease.

Abstract

Fundus fluorescein angiography was performed in 10 cases of occlusive carotid artery disease at presentation and after surgery or medical treatment. An improvement in the microcirculation of the retina was observed in 4 cases after carotid endarterectomy and in 1 case after carotid endarterectomy and extracranial-intracranial bypass. Improvement was not observed in 2 cases after extracranial-intracranial bypass alone or in 3 cases in which surgical intervention was not undertaken. Our results suggest that carotid endarterectomy is a more effective procedure than extracranial-intracranial bypass in improving retinal perfusion when compromised by ipsilateral carotid obstruction.
