FIG 2. Multimodal imaging before and after stent placement.

A, Intraarterial angiogram of the right common carotid artery before stent placement.

B, Plain radiograph showing the stent partially deployed within the vessel. Note the junction zone still within the microcatheter (arrow).

C and D, Intraarterial angiogram (plain and unsubtracted) immediately after stent deployment. Note the slightly irregular vessel surface at the stent site and the slight distal narrowing (arrows) due to vasospasm.

E and F, MR angiography, TOF (E) and contrast-enhanced (F) 3 days after stent implantation. The nitinol stent induces artifacts mainly at the proximal stent site due to the marker.

G and H, CT angiography, sagittal reformation (G) depicts the stent. 3D images (H) demonstrating the open vessel. Note the slightly irregular vessel surface at the stent site.

I, Intravenous angiogram 4 weeks after stent deployment. Note the second stent placed into the right subclavian artery (diameter 2.5 mm, length 20 mm). Both vessels are open without narrowing.
