FIG 1. Case 1.
A and B, Pretreatment anteroposterior (A) and lateral (B) views of the left internal carotid artery show stenoses of the cavernous segment and of the A1 segment of the left anterior cerebral artery (arrows).
C and D, After unprotected PTA, angiograms show a dissection of the cavernous carotid artery (closed arrow, C) and compromise of distal perfusion (open arrow, C). This progressed quickly to complete occlusion of the left internal carotid artery (D). Prompt reconstitution of the supraclinoid internal carotid artery via the ophthalmic artery (arrow, D) helped to mitigate the effects of the temporary occlusion.
E, Immediate reopening of the internal carotid artery is evident after placement of an AVE 3.5 x 8-mm GFX stent. Arrows indicate the stent placement.
F, Follow-up angiogram 6 months later shows healing of the stent site, and a smooth luminal contour.
