Successful retinal blood flow augmentation after extracranial-intracranial bypass

A 61-year-old woman visited us with recent onset right-side weakness. Magnetic resonance imaging showed ischemic changes at the left internal border zone due to occlusive disease affecting the left proximal internal carotid artery. Prompt oral dual antiplatelet therapy and intravenous fluid were administered with subsequent induced hypertension and without reperfusion therapy. Although the hemiparesis was improved, she complained of a new-onset transient left-side monocular visual loss. Fluorescein angiography confirmed delayed perfusion in the left eye. We performed extracranial-intracranial bypass for flow augmentation. After bypass, the amaurosis fugax resolved. Follow-up retinal fluorescein angiography also showed improved retinal perfusion.
