Fig 2. A 55-year-old woman, who initially presented with right-hemisphere watershed infarcts while taking aspirin, had additional transient ischemic attacks while taking aspirin, clopidogrel, and heparin during hospitalization. A, Initial imaging evaluation demonstrated a high-grade right supraclinoid ICA stenosis that was successfully treated with Wingspan PTAS (arrows depict the stent end markers). B, The patient returned with a history of falls and episodic left-handed and arm numbness and weakness 3.5 months after treatment. MR with diffusion imaging demonstrated several small right-hemisphere infarctions. C, Angiography demonstrated long-segment high-grade in-stent restenosis (right anterior oblique [left] and lateral [right] subtracted images). D, Corresponding right anterior oblique (left) and lateral (right) native images. This lesion was successfully retreated with angioplasty.
