应用心导管技术,经血管腔取出导管断端,可避免大型外科手术,避免因导管断端栓塞引起的其它并发症。本院心导管室检查过程中,发生1例猪尾管折断,采用 Cook 型 CRs-1套圈,经血管腔成功取出猪尾管断端。报告如下:1.对象:患者男性,52岁。因反复发作心前区剧烈疼痛3个月,运动平板心电图示可疑前壁心肌缺血,为明确诊断而行经股动脉穿刺途径冠脉造影和左室造影检查。冠脉造影过程顺利。当准备行左室造影检查,将 The use of cardiac catheterization, removal of the catheter end of the vessel cavity, to avoid large-scale surgery to avoid other complications caused by catheter stump embolization. In our hospital, 1 case of pigtail tube was broken during the cardiac catheterization. The Cook-type CRs-1 ferrule was used and the pigtail end was successfully removed via the vascular lumen. The report is as follows: 1. Object: Male patient, 52 years old. Due to repeated episodes of acute pain in precordial area for 3 months, exercise-plate electrocardiogram showed suspicious anterior myocardial ischemia, and to confirm the diagnosis by the femoral artery puncture coronary angiography and left ventricular angiography. Coronary angiography was successful. When preparing for left ventricular angiography, will
