We describe our experience with a technique for PTCA of total coronary occlusions using the ultra low profile balloon on wire Probe. An intracoronary Probing Catheter was used to facilitate crossing the stenosis with a guide wire. This was followed by exchanging the guide wire for the Probe into the obstruction for balloon dilatation. This technique was used in 22 consecutive patients undergoing PTCA for chronic total occlusion. The total obstruction could be crossed by guide wire (0.014 flex or 0.016 standard) passed through Probing Catheter in 19 patients (86%). The obstruction could be successfully dilated by the Probe, delivered through the probing catheter, in 17 of these patients. Of the remaining 2 patients, one could be dilated by sequential dilatation using over the wire low profile balloon system and the other one by dilatation with the Probe, respectively. The Probing Catheter technique offers a new method to apply balloon on wire technology to the dilatation of chronic total coronary occlusions with very promising results.
我们描述了使用超低压球囊导丝探头对完全性冠状动脉闭塞进行经皮冠状动脉腔内血管成形术（PTCA）的经验。使用冠状动脉内探测导管，以便用导丝穿过狭窄部位。随后将导丝换成探头，送入阻塞部位进行球囊扩张。该技术应用于22例连续接受PTCA治疗慢性完全闭塞的患者。19例患者（86%）通过探测导管送入的导丝（0.014软头或0.016标准型）能够穿过完全阻塞部位。在这些患者中，17例通过经探测导管送入的探头成功扩张了阻塞部位。其余2例患者中，1例使用导丝超低压球囊系统序贯扩张，另1例使用探头扩张。探测导管技术为将球囊导丝技术应用于慢性完全性冠状动脉闭塞的扩张提供了一种新方法，结果非常有前景。
