Anti-Inflammatory Effects of Arsenic Trioxide Eluting Stents in a Porcine Coronary Model
Figure 3
Typical SEM images (magnification: ×500, ×100 for insets) of the inner wall of stented arteries 1, 2, and 4 weeks after implantation (a) and relaxation responses of coronary segments distal to stents within 6-month followup (b). At the first week, both AESs and BMSs showed quite few endothelial cells attachment. For the second week of development, the endothelialization of AESs was slightly higher than BMSs (). After 4 weeks, the arteries treated with BMS or AESs were fully endothelized. The diameter changes between the BMSs, PCSs, and AESs had no significant differences of vasoreactivity in response to the Ach infusion in sites distal to the stents within 6-month followup.
