title: [Is Palmaz-Schatz stenting effective for second restenosis?].
abstract: The long-term outcome after coronary stent placement in restenotic lesions after balloon angioplasty (percutaneous transluminal coronary angioplasty: PTCA)may be less favorable compared to stent treatment of de novo lesions, but the role of stents in restenotic lesions after 2 prior PTCA procedures is unknown. Elective Palmaz-Schatz stent placement was performed in 124 consecutive patients. Stents were placed in 70 patients(56%) in the native coronary arteries for de novo lesions(de novo group), in 33 patients (27%)for restenotic lesions after one prior PTCA(restenosis group), and 21 patients(17%)for restenotic lesions after 2 prior PTCA(second restenosis group). The 3 groups were well matched with respect to lesion type, lesion length, and reference diameter. Stent size was similar in the 3 groups. Follow-up angiograms taken about 6 months after stenting were available for all patients. The restenosis rate after stenting was similar for the de novo group and restenosis group(19% vs 27%, NS). The second restenosis group tended to have a higher restenosis rate after stenting than the de novo group(38% vs 19%, p = 0.06). The frequency of diffuse type in-stent restenosis of the second restenosis group tended to be higher than that of the de novo group(63% vs 13%, p = 0.08). Our results suggest that the restenosis rate after stenting was higher in patients with repeated restenosis. Therefore, other therapeutic methods should be considered.
