In 100 patients who underwent coronary angioplasty with more than one balloon catheter for a lesion, these over-the-wire balloon catheters were changed by using a regular-length guidewire. In order to change to another balloon, the inflation device was connected to the central guide wire lumen of the catheter after pulling back the catheter until the proximal end of the regular length guide wire disappeared. By pulling back the balloon catheter from the guiding catheter by applying a pressure with the inflation device, the balloon was taken out of the guiding catheter leaving the wire in the coronary artery. One hundred forty-nine of 163 attempted procedures were completed successfully. Our technique helped in performing a fast, safe, and reliable changing procedure compared to the procedure with an extended guidewire.
在100例因病变使用多个球囊导管进行冠状动脉血管成形术的患者中，通过使用常规长度导丝更换这些过线球囊导管。为了更换另一个球囊，在将导管回撤直到常规长度导丝的近端消失后，将充盈装置连接到导管的中央导丝腔。通过用充盈装置施加压力将球囊导管从引导导管中回撤，将球囊从引导导管中取出，而导丝留在冠状动脉内。163例尝试的操作中有149例成功完成。与使用延长导丝的操作相比，我们的技术有助于进行快速、安全和可靠的更换操作。
