Clinical Efficacy of Stent-balloon-stent (SBS) Technique in the Treatment of Coronary Bifurcation Lesions

Patients with coronary bifurcation lesions underwent stent-balloon-stent (SBS) technique. The procedure of this technique is to implant the stent into the side branch at the 1\~2mm, which is away from the opening of the branch, and then implant the stent into the main vessel. The guide wire enters the side branch from the mesh at the distal end of the main vascular stent, and the drug balloon is used to dilate the opening of the side branch, so that the opening area of the side branch is more than 5mm².
