Figure 1. Time-of-flight magnetic resonance angiography (TOF-MRA) revealed a gradual decrease in the signal intensity of the left proximal intracranial vertebral artery (VA) (A). Postoperative TOF-MRA revealed normalized signal intensities between bilateral VA (B).

Figure 2. Angiography showed an occlusion at the origin of the left subclavian artery (SA), reversed flow in the left vertebral artery (VA), and identified subclavian steal syndrome (A). Percutaneous transluminal angioplasty with stenting for the proximal left SA occlusion was performed (B), which revealed normal flow in the left VA (C).
