Techniques for uncoiling knots formed in catheters during angiography have been the subject of several previous reports. A new technique for catheter unknotting is presented, based on the use of graded flexibility guidewires. The application of this graded taper method appears particularly pertinent to uncoiling softer, narrow-caliber, adversely looped catheters. Moreover, the mechanisms of knot uncoiling in the previous reports are reassessed and their imprecisions corrected.
血管造影过程中解开导管中形成的结的技术是先前几份报告的主题。本文介绍了一种基于使用渐变柔韧性导丝的导管解结新技术。这种渐变锥度方法的应用似乎特别适用于解开较软、窄口径、形成不良环圈的导管。此外，对先前报告中结解开的机制进行了重新评估，并纠正了其中的不准确之处。
