Figure 3.

The sequential change of the diameter of the stent (shaded circles), the perfusion lumen (unshaded triangles) and the thickness of in-stent hypodense areas (shaded triangles) are demonstrated. The left graph shows the sequential change in the group with thrombus: The in-stent hypodense areas were recognized at two weeks after carotid artery stenting. The right graph shows the sequential change in the group without thrombus: No hypodense areas were recognized at two weeks after stenting.
