Abstract

Objective To investigate the efficacy of intravascular ultrasound(IVUS)-guided drug-eluting stent(DES)for the treatment of in-stent restenosis.Methods Fourty-five stent restenosis lesions of 43 consecutive patients with stent restenosis lesions were initially checked by IVUS.The size and length of DES were chosen depending on the results of IVUS.The dilating pressure 13±5atm of DES and post-dilation 15±7atm were decided by the results of IVUS either.Results The IVUS showed that the old stents were not usually completely dilated(38%)and not tightly contacted with the arterial wall(24%).The follow-up of angiography in 29 patients indicated that the re-restenosis in the patients treated by IVUS-guided DES was small(1 case,3.4%).Conclusion The results suggest that IVUS-guided DES is effective for the treatment of in-stent restenosis
