Abstract

Aim. To study effectiveness of various types of coronary stenting in bifurcation stenoses. Material and methods. Fifty six patients with bifurcation stenoses were divided into 2 groups: stenting of the basic and side branch of the coronary artery (CA) was made in group 1 patients (n = 27), stenting of the basic branch and balloon angioplasty of the side branch were made in group 2 (n = 29). Primary clinical and angiographic response reached 96 and 90% in groups 1 and 2, respectively. Complications were absent in group 1, occurred in 13.7% cases in group 2 (the difference was insignificant). One year after the procedure lethal outcomes were absent. The number of unfavourable clinical outcomes was higher in group 1 (25.9 and 13.7%, respectively, p = 0.4). The rate of restenoses detected angiographically was not significantly different in group 1 and 2 (33 and 26%, respectively). Conclusion. Stenting of bifurcation stenoses brings about good short-term and satisfactory long-term results in most of the patients. The rate of the complications was low. Two stents implantation (in basic and side branches) has no significant advantages over stenting of the basic CA and balloon angioplasty of its side branch.
