Abstract
In order to investigate the relationship between restenosis and the morphology detected by coronary angioscopy (CASC) and introvascular ultrasound imaging (IVUS),17 patients were detected by CASC and IVUS immediately and 3 months after percutaneous transluminai coronary angioscopy (PTCA).The results showed that the dilation index by IVUS (Dlu) was significantly lower in restenosis patients than in non-restenosis patients (0.42±0.08 versus 0.78±0.16, P<0.01) and that the elastic recoil (ER) was higher in restenosis patients than in non-restenosis patients (4.51±1.42mm~2 versus 1.63±1.20 mm~2, P<0.01), and that the elastic recoil rate (ERR) was also higher in restenosis patients than in non-restenosis patients (57.3±8.07% venus 21.80±16.84% P<0.01),and that coronary dissection,atheromatous plaque and calcification as well as the coiour of inner coronary artery had no relation with chronic restenosis.In conclusion,the elastic recoil is one of the important factors of chronic restcnosis after PTCA.
