Chronic total occlusion remains a relative contraindication and the main cause of failure of coronary angioplasty. Previously available hydrophilic guidewires had numerous limitations. The Crosswire is a new 0.014" hydrophilic nitinol guidewire which can be accommodated by very-low-profile balloon catheters and has a shapeable and highly radiopaque platinum-iridium coiled tip. This guidewire was used in 55 patients with 56 chronic coronary occlusions in which recanalization by conventional guidewires had failed. Clinical success was 79%. Coronary perforation occurred in two cases, one of them requiring pericardiocentesis for tamponade. These results illustrate the usefulness of this new guidewire in the treatment of chronic total occlusions.
慢性完全闭塞仍然是冠状动脉成形术的相对禁忌证和主要失败原因。以前可用的亲水导丝有许多局限性。Crosswire是一种新型的0.014英寸亲水镍钛合金导丝，可通过极薄型球囊导管使用，其尖端为可塑形且具有高显影性的铂铱合金线圈。该导丝用于55例患者的56处慢性冠状动脉闭塞病变，这些病变使用传统导丝未能实现再通。临床成功率为79%。发生了2例冠状动脉穿孔，其中1例需要心包穿刺引流进行心包填塞。这些结果表明这种新型导丝在慢性完全闭塞病变治疗中的有效性。
