Patients with amaurosis fugax and hemispheric transient ischemic attacks cannot be significantly differentiated based on clinical and arteriographic findings, contrary to prior reports.
No differentiation between amaurosis fugax and hemispheric TIAs on clinical or arteriographic grounds; challenges prior reports but hypothesis-generating in Level 4 data.
Eighty-seven patients with either amaurosis fugax (40 patients) or hemispheric transient ischemic attacks (47 patients) were studied to determine whether the two symptom groups could be differentiated clinically and arteriographically. Clinical data assessed were age of patient, incidence of cardiac disease, and presence of claudication, hypertension, diabetes, and carotid bruits. Contrary to a prior report, our results indicate no significant difference between the 2 patient groups based on clinical and arteriographic findings.
