[A comparative analysis of the immediate and late results of coronary balloon angioplasty in bifurcation stenoses performed by the traditional method and by the "2-guide" method].
To evaluate the efficiency of balloon coronary angioplasty (BCA) for bifurcation stenoses, which had been made by the two-guide method, the results of the angioplasties were examined in 147 patients with coronary heart disease. BCA had been performed routinely in 54 patients and by the two-guide method in 32. Sixty-one patients undergone angioplasty for nonbifurcation lesions served as a control group. In the group of routine BCA procedure, poor results with residual stenosis of the major vessel were seen in 13% of cases, the incidence of complication (dissection of unfavourable types, thrombosis of the major vessel) was 29.6%. In the two-guide BCA, these indices were 15.6 and 2%, respectively, the incidence of restenosis was 46.9% and that of branch lesions was 6.3%. The findings have led to the following conclusions that routine angioplasty of bifurcation stenoses yields poor early and late results of dilatation of lateral branches. The use of the two-guide method substantially reduces the risk of damage to a lateral branch, improves immediate dilatation of the major vessel, yet fails to affect the number of restenosis in the late period.
