- Fig 1.
Left common carotid artery angiography showing pseudo-occlusion of internal carotid artery. Oblique view (A) and lateral view (B). The internal carotid artery filling was delayed regarding to the external carotid artery. C, Immediate control after stent deployment (7 × 40 mm Carotid Wallstent) and postdilatation with a 4 × 20 mm balloon. No predilation was performed.

A, selective angiogram that shows a high-grade stenosis of >90% in the left internal carotid artery due to a great atheromatous plaque with calcification. B, After sent deployment (7 × 40 mm Carotid Wallstent), a significant residual stenosis is revealed despite performing a postdilation with a 4 × 20 mm balloon. C, Final result after a second overlapped stent placement with no residual stenosis.
