Imaging findings from a 72-year-old man (case 2) with partial motor aphasia and right-limb hemiplegia for 17 hours. (A) Magnetic resonance angiography (MRA) revealed an occluded left anterior cerebral artery A3 segment. (B) Digital subtraction angiography confirmed the MRA findings. (C) After 10 mL of tirofiban was infused into the occluded vessel, the left anterior cerebral artery A3 was recanalized; however, stenosis remained. (D) After 1 week, repeat head MRA revealed that residual stenosis of left intracranial artery A3 had disappeared completely.
