【摘要】 目的:评价改良拘禁球囊技术对冠状动脉分叉病变分支开口的保护作用。方法:回顾性分析2020年2月～2022年2月黄山市人民医院行经皮冠状动脉介入治疗的冠状动脉分叉病变患者临床资料。根据既往文献报道，主支支架术后边支闭塞的发生率为4.4%～17.31%,本研究以4.4%的最小发生率作为参考，比较其与改良拘禁球囊术式所致的边支闭塞率的差异，使用R和EZR软件收集和分析数据。结果:226例患者使用改良拘禁球囊技术进行经皮冠状动脉介入治疗，所有患者均未发生边支闭塞，改良拘禁球囊具有显著优越性。结论:改良拘禁球囊技术在冠脉分叉病变治疗中能更安全、有效地保持边支的通畅性。更多还原

【Abstract】 Objective:To evaluate the protective effect of modified jailed balloon technique(M-JBT) on the coronary artery bifurcation lesions.Methods:Clinical data were reviewed in the patients with coronary artery bifurcation lesions treated by percutaneous coronary intervention(PCl) in our hospital between February 2020 and February 2022.According to previous reports, the incidences of side branch(SB) occlusion after main branch(MB) stenting ranged from 4.4% to 17.31%.Therefore, minimum incidence of 4.4% in these literatures was considered as the reference incidence to compare SB occlusion rate with M-JBT.Data were collected and analyzed by using R and EZR software.Results:In total, 226 patients underwent PCI using M-JBT.No occlusion of side branch occurred, which suggested that M-JBT had obvious advantages.Conclusion:M-JBT is safe and effective in the preservation of SB patency during bifurcation stenting.更多还原
