A, 81-year-old man who presented with recurrent left carotid artery TIAs (right-sided weakness and expressive aphasia). PA left carotid arteriogram reveals a focal but eccentric stenosis at the petrocavernous junction (arrow). The lesion is short, eccentric, and along a curve in the vessel; the vessel is >3 mm in diameter and proximal and is typical of the lesions treated with stent placement. B, Appearance immediately after stent placement. Note a small dissection (arrow). C, Appearance 6 weeks later demonstrates healing of the dissection. D, Appearance 4 years after stent placement. The mild residual stenosis remains and the patient remains asymptomatic.
