FIG 3. This 61-year-old woman had repeated vertebral basilar TIAs while receiving warfarin.
A and B, Anterior pretreatment right vertebral artery angiograms (magnified image in D) show severe stenosis of the proximal basilar artery.
C and D, Anterior right vertebral artery angiograms obtained immediately after angioplasty show improvement in the stenosis but continued moderate luminal narrowing.
E and F, Angiograms obtained 2 months after angioplasty show mild improvement in the stenosis with remodeling. At last follow-up (60 months), the patient did not have additional symptoms.
