Subclavian artery stenosis presenting as amaurosis fugax: a case report

Abstract

Objective: We report a case of subclavian arterial stenosis manifesting as transient amaurosis for which a favorable outcome was achieved by stenting.
Case presentation: The patient was a 71-year-old female with transient amaurosis. Stenosis of the left subclavian artery was noted on three-dimensional computed tomographic angiography (3D-CTA). The left ophthalmic artery was also occluded, in addition to the left subclavian arterial stenosis, on digital subtraction angiography (DSA). Stenting was applied to the left subclavian artery, and successful dilation was obtained. In addition, the transient amaurosis was resolved after normal blood flow had resumed.
Conclusion: Subclavian arterial stenosis manifesting as transient amaurosis is rare, and angiography is useful to confirm the pathology. Stent placement in the stenosed segment of the subclavian artery is minimally invasive and can be safely performed.
