Performing coronary angiography in very older patients can prove a challenge due to vessels calcification and torturousity. Manipulation of coronary catheters to engage the artery ostium may result in over twisting and can result in complications ranging from a minor 'kink' to a complex 'knot'. The authors describe a novel method to retrieve the complex twisted coronary catheter using snare technique, after usual steps to remove the coronary catheter failed.
由于血管钙化和迂曲,在高龄患者中进行冠状动脉造影可能是一项挑战。操纵冠状动脉导管以进入动脉开口可能会导致过度扭转,并可能导致从轻微“扭结”到复杂“打结”的各种并发症。作者描述了一种在常规移除冠状动脉导管的步骤失败后,使用圈套技术取回复杂扭曲冠状动脉导管的新方法。
