The aim of the present study was to investigate the effect of intravascular ultrasound (IVUS)-guided stenting on angiographic results for drug eluting stent (DES) implantation. Material-Methods: For the present study, we included 30 patients who received DES with IVUS-guided stenting (Group A) and 30 patients receiving the DES without IVUS-guided stenting (Group B). The patients were evaluated for their ninth month control angiographies and were followed during two years for the development of relevant clinical events after the DES implantations. The angiographic and clinical results were compared between the groups. Results: After the percutaneous intervention, the minimal luminal diameter and net acute gain were significantly increased in Group A in respect to Group B (3.3AE0.34 vs. 2.8AE0.33, p <0.01). By contrast, stent restenosis rates were similar between the groups (p >0.3). Conclusions: The present results indicate that the use of IVUS for the implantation of DES can increase the success rate of the intervention. We think that the IVUS guidance during DES implantation can be complementary percutaneous intervention, in particularly by detecting the situations that need for post-dilatation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
