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 direct Ikari guide catheter in patients with acute ST segment elevation who underwent coronary angiography and coronary artery intervention (PCI) via radial artery. Methods Fifty-six patients (Ikari group) with single Ikari-guided catheter were enrolled in the emergency department of acute ST-segment elevation myocardial infarction (PCI). Sixty-three patients (control group) underwent coronary angiography. The catheterization time, radiography time, D2B time, C2B time, operation time and fluoroscopy time were compared between the two groups. Results The success rate of both groups was 100.0%, there was no significant difference between the two groups (P> 0.05). Contrast dose, D2B time, C2B time, operation time and fluoroscopy time in Ikari group were shorter than those in control group (P <0.01 or 0.05). Conclusions The application of single Ikari guide catheter in emergency ST-segment coronary angiography and PCI is safe and feasible in acute ST-segment elevation myocardial infarction. It can significantly reduce D2B time, C2B time, operation time, fluoroscopy time and contrast medium dosage.
