The use of the coronary stents with covering in the treatment of patients with relapse of a stenocardia after coronary bypass

Abstract

The results of the endovascular procedures at 66 patients with relapse of a stenocardia after coronary shunting are analyzed. The coronary stents with a covering are implanted to 26 patients; coronary stents without a covering are implanted to 40. Control group — 36 cases when coronary angioplasty and stenting were done as primary intervention. By the end of the hospital period positive clinical dynamics of the revascularization is marked at 76.9% of patients of the 1st group, 77.5% — 2^nd and 88.9% — 3^rd. In the remote period (6—24 months) relapse of a stenocardia is revealed at 15.4% of patients of the 1^st group, 35% — of the 2^nd group and 30.6% — of the 3 rd group. Angiographically confirmed resthenosis of the stented segment was revealed at 32.5% of the patients of the 2^nd group and 25% - 3^rd, and no one cases of the resthenosis in the 1^st group. The frequency of the repeated endovascular procedures was 23.1 % in the 1^st group, 30% - in the 2^nd group and 30.5% - in the 3^rd group.
