Following successful guidewire passage, inability to cross a chronic total occlusion is the most frequent cause of procedural failure. While low-profile balloons, microcatheters, and specialty catheters such as the Tornus have been designed to facilitate lesion crossing, these devices require adequate guiding catheter support. We describe a novel application of the Tornus catheter combined with a balloon-anchored guide technique to successfully recanalize an otherwise difficult to cross chronic total occlusion.
在导丝成功通过后，无法穿过慢性完全闭塞病变是手术失败最常见的原因。虽然已设计出低轮廓球囊、微导管以及如Tornus等特殊导管以促进病变穿过，但这些器械需要足够的引导导管支撑。我们描述了一种Tornus导管与球囊锚定导丝技术相结合的新应用，以成功再通原本难以穿过的慢性完全闭塞病变。
