Abstract

Abstract:

BACKGROUND: Both distal-wire anchoring technique and branch-balloon anchoring technique are the effective ways of improving the ability to deliver stents to the target lesions. There is no study addressing the comparison of these two techniques in the successful stent delivery to stenosis lesions at present.
OBJECTIVE: To evaluate the clinical effect of distal-wire anchoring technique versus branch-balloon anchoring technique in delivering stents to complex lesions.
METHODS: We retrospectively analyzed the clinical data of 87 cases of difficultly delivering stents in the process of coronary intervention, in which 46 cases were treated with branch-balloon anchoring technique and 41 cases treated with distal-wire anchoring technique. Then, stent implantation rate, major adverse cardiac reactions and recurrence of angina pectoris within 12 months, and late lumen loss, restenosis after stent implantation were compared between the two groups.
RESULTS AND CONCLUSION: The successful stenting rate of distal-wire anchoring technique group was significantly higher than that of branch-balloon anchoring technique group (83% vs. 61%, P < 0.05). There were no significant differences between two groups patients in complications during stenting, major adverse cardiac reactions and recurrence of angina pectoris within 12 months, and late lumen loss, restenosis after stent implantation. The study indicates that the distal-wire anchoring technique is of safety and effectiveness method for dealing with inability to deliver stents to the target lesions.
