A retrospective review was done on 13 consecutive patients who underwent PTCA of totally occluded coronary arteries using a recently released thin shaft balloon over-the-wire angioplasty system. Balloon size was determined by the closest fit to the arterial size and used without predilatation techniques. This technique was initially successful in 12 patients with only 2 clinically insignificant episodes of distal embolization and one probable early reclosure. Using thin shaft angioplasty systems, balloon dilatation of totally occluded coronary arteries can be done safely with a single balloon in many cases resulting in simplified procedures and economic benefits.
对13例连续接受经皮冠状动脉腔内血管成形术（PTCA）的患者进行了回顾性研究，这些患者使用了最近发布的细轴球囊超滑导丝血管成形术系统对完全闭塞的冠状动脉进行治疗。球囊大小根据与动脉大小最匹配的尺寸确定，且未采用预扩张技术。该技术最初在12例患者中取得成功，仅出现2次临床意义不大的远端栓塞事件和1次可能的早期再闭塞。使用细轴血管成形术系统，在许多情况下，单球囊即可安全地对完全闭塞的冠状动脉进行球囊扩张，从而简化操作并带来经济效益。
