目的 探讨支架增强显影技术在冠脉分叉病变介入治疗中的作用。方法 选择2016-01至2016-06就诊于医院心内科,并行介入治疗的37例分叉病变患者临床资料,支架增强显影技术(stent boost subtract, SBS)采用荷兰PHILIPS AlluraXper FD20/10全数字血管造影机完成,根据支架柱及导丝的可视性将图像质量分为三个等级:(1)可视性优,即显影良好;(2)可视性次优,即显影欠佳,但不影响术者判断;(3)可视性差,即显影模糊,影响术者判断。结果 采集并分析了196个SBS图像,其中,75.6%的支架柱及导丝的可视性优;21.6%的支架柱及导丝的可视性次优,2.7%的患者支架柱及导丝的可视性差。结论 支架增强显影技术作为一种简捷、快速的成像方式,可通过增强支架柱及导丝的可视性指导优化支架精确定位、球囊后扩张、边支导丝再进入及球囊对吻等,在各个环节指导优化分叉病变的介入治疗。
Abstract
Objective To evaluate the effect of StentBoost Subtract in guiding optimized percutaneous coronary intervention in patients with bifurcation lesions. Methods Between January 2016 and June 2016, clinical data on a total of 37 consecutive patients was collected .SBS was performed using AlluraXper FD10 or FD20.The quality of the images was divided into three grades according to visualization of stent struts and guidewire: optimal(good imaging), suboptimal visualization(not good enough, but does not affect judgment ), and poor visualization(fuzzy imaging that affects judgment).Results A total of 196 images were collected and analyzed in this study. 75.6% of the patients were evaluated as of optimal visualization of stent struts and guidewire, 21.6% as of suboptimal visualization and 2.7% as of poor visualization.Conclusions As a simple and quick means of imaging , StentBoost Subtract can be used to guide optimized PCI in bifurcation lesions step by step via enhancing visualization of stents and guidewire, such as accurate stent positioning, post-dilation, rewiring of the guidewire and kissing balloon technology.
