Abstract:
50% and was classified as in-stent if inside stent or in-segment if located within the stented segment plus the 5 mm segments distal or proximal to the stent margins. Results Among the 8 patients included in this analysis, 5 had in-segment restenosis and 3 had in-stent restenosis (2 were not real in-stent restenosis and were just due to underexpansion). IVUS showed all restenosis occurred as localized lesion. Conclusion Restenosis after drug-eluting stents implantation is frequently associated with local trauma outside the stented segment and incomplete lesion coverage by the drug-eluting stent. Restenosis usually occurs proximal to the stent and presents as a localized lesion.
