Amaurosis fugax.

We reviewed 112 patients with amaurosis fugax to refine our indications for carotid angiography. Eighty patients had a carotid endarterectomy. Thiry-four patients with ipsilateral hemispheric transient ischemic attacks plus amaurosis fugax all had an operable carotid lesion. The presence or absence of a carotid bruit, a normal or abnormal ophthalmologic examination, or a normal or abnormal cerebrovascular Doppler examination did not predict which patients would or would not have an operable carotid lesion. All patients with amaurosis fugax being evaluated for an operable carotid stenosis require angiography.
