Fig. 3.

A 49-year-old male presented with the left arm weakness.

A. Lateral view of the right internal carotid arteriogram shows a severe stenosis of the cavernous segment of the internal carotid artery.

B. Post-stenting angiogram shows no residual stenosis.

C. One-year follow-up angiogram shows good patency of the stented segment of the internal carotid artery with a 20% stenosis at the distal stent margin. Note a patent side branch of the cavernous segment of the internal carotid artery. The patient recovered completely and had no symptom recurrence during the one-year follow-up period.
