Although stents reduce the restenosis rate, stent continues to be a major problem and optimal treatment of is still controversial. In this study, we aimed investigate angiographic recurrent rate at 6-12 months after successful cutting balloon angioplasty (CBA) for bare metal restenosis.Thirty patients (mean age: 57.9 ± 11.6, 22 males) undergoing CBA in-stent our hospital were prospectively included in study. Control coronary angiography was performed CBA. Lesion length, minimal lumen diameter (MLD), reference vessel analyzed by computerized digital analysis. Recurrent defined as lesions obstructing more than 50%. We described shorter 10 mm focal those longer diffuse. used Student t, Chi-square, Mann-Whitney U tests statistical analysis.Two had two distinct lesions; therefore, 32 assessed. There 9 (28.1%) on control angiography. developed 3/21 (14.3%) type 6/11(54.5%) diffuse (p=0.035). Pre-procedural MLD lower restenotic group compared non-restenotic (0.41 0.29 vs. 0.64 0.17 mm, p=0.048) while percent stenosis higher (76.8 12 69.6 5.37%, p=0.029).In selected patients, an effective safe method restenosis. might considered first-line with lesions.
