经桡动脉单根lkari指引导管行急诊冠状动脉造影及PCI的评价

A Single Ikari Guiding Catheter for Transradial Coronary Angiography and Intervention in Patients with Acute ST Elevation Myocardial Infarction

目的探讨急性ST段抬高患者经桡动脉应用单根Ikari指引导管直接行冠状动脉造影及冠状动脉介入(PCI)治疗的可行性和安全性。方法收集急性ST段抬高心肌梗死行急诊经桡动脉PCI治疗的患者,其中使用单根Ikari指引导管者56例(Ikari组).使用左右冠状动脉共用造影导管者63例(对照组)。比较两组患者导管-造影时间、造影时间、D2B时间、C2B时间、操作时间、透视时间。结果两组穿刺置管成功率均为100.0%.导管-造影时间、造影时间无明显差异(均P>0.05)。Ikari组患者造影剂用量、D2B时间、C2B时间、操作时间和透视时间小于对照组(P<0.01或0.05)。结论急性ST段抬高心肌梗死应用单根Ikari指引导管行急诊冠状动脉造影和PCI是安全可行的,能明显减少D2B时间、C2B时间、操作时间和透视时间及造影剂用量。

Objective To investigate the feasibility and safety of using a single Ikari guiding catheter for transradial coronary angiography（CAG） and percutaneous coronary intervention（PCl） in patients with ST elevation myocardial infarc- tion （STEMI）. Methods Patients with STEMI underwent emergent CAG and primary PCI via a single Ikari guiding catheter （Ikari group, .=56） or underwent CAG via Tiger catheter and primary PCI via guiding catheters （control group, .=63）. Catheterization-to-angiography time,angiographic time, door-to-balloon （DTB） time, cathlab door-to-balloon （CTB） time, procedure time and fluoroscopy time were analyzed. Results Radial artery cannulation was successful in all patients. There was no significant difference between two groups in catheterization-to-angiography time and anglo- graphic time（P 〉0.05）. Contrast consumption, DTB time, CTB time, procedure time and fluoroscopy time were significantly lower in Ikari group than in control group （P〈0.01 or 0.05）. Conclusion A single Ikari guiding catheter is feasible and safe for CAG and Primary PCI in patients with STEMI, which may shorten DTB time, CTB time, procedure time and fluo- roscopy time and reduce contrast consumption.
