What are the arteriographic findings in patients presenting with amaurosis fugax?
What are the arteriographic findings in patients presenting with amaurosis fugax?
Amaurosis fugax is not a specific indicator of internal carotid artery stenosis, as only one third of patients have treatable atherosclerotic lesions.
Amaurosis fugax warrants evaluation beyond assumed carotid stenosis; leaves open etiology and optimal workup in most cases.
Fifty-nine patients had arteriography because of episodes of amaurosis fugax. Only one third of them had atherosclerotic lesions potentially treatable by carotid endarterectomy. Another third had normal arteriograms, some of these had migraine, heart disease or platelet disorders presumed to be the cause of their symptoms. Patients with amaurosis fugax are a heterogeneous group, and their visual symptoms should not be considered a specific indicator of stenosis of the internal carotid artery.
