A tapered teflon dilator has been applied to 12 cases of percutaneous transluminal coronary angioplasty (PTCA). The technique was first used to predilate stenoses that could not initially be crossed with low profile over the wire PTCA balloons. In the first five cases, three angioplasties that would have been failures were converted to successes by this method. The dilator was used in place of a balloon catheter as an initial step to assess the ability of a guidewire to cross a lesion to reduce cost in five additional cases. Modification of an existing family of peripheral vascular dilators is described. The method of application of this technique to PTCA is outlined.
一种锥形聚四氟乙烯扩张器已应用于12例经皮腔内冠状动脉成形术（PTCA）。该技术首先用于预扩张那些最初无法通过低轮廓导丝PTCA球囊穿过的狭窄病变。在前5例病例中，通过这种方法使原本会失败的3例血管成形术转变成了成功案例。在另外5例病例中，使用扩张器代替球囊导管作为评估导丝穿过病变能力的初始步骤，以降低成本。描述了对现有的外周血管扩张器系列的改良。概述了将该技术应用于PTCA的方法。
