The Risk of Stroke in Patients With First-Ever Retinal vs Hemispheric Transient Ischemic Attacks and High-grade Carotid Stenosis

Abstract

To our knowledge, this study is the first report on the expected outcome for medically treated patients with high-grade (70% to 99%) carotid stenosis in whom the first-ever event was either an RTIA or HTIA. The presence of RTIAs carries a considerable risk of ipsilateral strokes, particularly at higher degrees of stenosis. However, in comparison with HTIAs, patients with RTIAs still have a better prognosis.
