Abstract: Objective To evaluate and compare the efficacy of drug-eluting stents (DES) and cutting balloon (CB) for the management of in-stent restenosis (ISR). Methods The immediate and (6.0±1.4) months follow-up angiographic outcomes of 124 patients with ISR who were treated by drug eluting stents and cutting balloon were analyzed in this retrospective study. Results Baseline characteristics and angiographic profile were similar between these two groups. There was no statistically significant difference between two groups both in acute post procedure minimum lumen diameter (2.54±0.45 vs 2.67±0.48 mm, P>0.05) and diameter stenosis (23.5% vs 21.8%, P>0.05) between DES and CB groups. At six-month follow-up study, however, the DES group showed significantly larger in the minimum lumen diameter (1.86±0.63 mm) than the CB group(1.34±0.71 mm) (P<0.01), and the diameter stenosis in the DES group was lower than that in the CB group(39.2% vs 47.8%,respectively,P<0.05).Furthermore, the recurrent restenosis rate as well as lumen loss in the DES group (4.1% and 0.52±0.48 mm, respectively) were significantly lower compared with those of CB group (9.8% and 0.74±0.53 mm, respectively with P<0.01). Conclusion Drug-eluting stents is comparable with cutting balloon in terms of immediate outcomes but superior to the latter in terms of efficacy at 6-month follow-up.
