Figure 3 Comparison between the delivered dose at 10% and 90% of the adventitia (DV10, DV90), the reduction of the intimal hyperplasia and the increase in external elastic lamina (EEL) area. Note the increased intrastent intimal hyperplasia (IIH) at the stent edges. These segments absorbed lower doses than the stent body but higher doses than the peri-stent segments, which exhibit less intimal hyperplasia. Expansive remodeling occurs within the stent body but not at the edges and the peri-stent segments.
