Percutaneous valve implantation is a recognized therapy for calcific aortic stenosis in those patients who are inoperable or at high surgical risk. The transfemoral approach is the most frequently used method for device delivery, but a tortuous calcific aorta and the inflexibility of large-caliber endovascular equipment can impede progress or even cause the procedure to be abandoned. Herein, the use of a technique employing a snare to safely overcome device obstruction in the aortic arch of an elderly female patient is described. The technique may be of practical value whenever any large-caliber device is obstructed in the circulation.
经皮瓣膜植入术是一种公认的针对无法手术或手术风险高的钙化性主动脉瓣狭窄患者的治疗方法。经股动脉途径是输送器械最常用的方法，但迂曲的钙化主动脉和大口径血管内设备的柔韧性不足可能会阻碍手术进程，甚至导致手术放弃。在此，描述了一种使用圈套器技术安全克服老年女性患者主动脉弓中器械梗阻的方法。每当任何大口径器械在循环中发生梗阻时，该技术可能具有实际价值。
