摘要

我们提出了一种简单的新技术,在冠状动脉直角弯曲处穿过钙刺,方法是在钙刺上部署一个非扁平气球,在钙刺处,通过的支架尖端经常碰到,并在支架向前推进时造成困难。当我们在钙刺上展开气球时,支架的尖端不会碰到钙刺的边缘,支架在亲水性光滑的气球上轻轻向前滑动。我们描述了一个罕见的右冠状动脉前起源异常的介入病例,我们无法将支架穿过两个90°弯曲处,这两个弯曲处有钙刺。尽管我们采用了伙伴线和三线技术使弯曲变直,但我们无法向前移动支架,每次支架都会碰到钙刺的边缘。我们每次放置一个2 mm×10 mm的非平坦半顺应性球囊,同时穿过覆盖钙刺的直角弯曲处,并在球囊上方,我们可以很容易地向前滑动支架,将支架部署在病变处,并实现远端TIMI III流动。我们描述了一种简单的新技术,即“在球囊上滑动支架技术”,以穿过保留在90°弯曲处的钙刺,这会导致支架向前谈判困难。

Crossing the calcium spur with “sliding over the balloon technique” in anomalous anterior origin of right coronary artery with two right-angle bends
We present a simple novel technique of crossing the calcium spur at right-angle bend in coronary artery by deploying a noninflated balloon over the calcium spur where the tip of the passing stent frequently hits and create difficulty in negotiation of the stent forward. When we deploy a balloon over the calcium spur, the tip of the stent does not hit the edge of the calcium spur and the stent gently slides over the hydrophilic slippery balloon forward with ease. We describe a rare case of intervention in anomalous anterior origin of right coronary artery where we were not able to pass the stent across two 90° bends which were harboring calcium spur. In spite of we adopted buddy wire and triple wire technique to make the bend straight, we were not able to move the stent forward, each time it was hitting at the edge of the calcium spur. We put a 2 mm × 10 mm noninflated semicompliant balloon each time while crossing the right-angle bend with calcium spur which covered the calcium spur and over the balloon we were easily able to slide the stent forward, deployed the stent across the lesion, and achieved distal TIMI III flow. We describe this simple novel technique of “sliding the stent over the balloon technique” to cross the calcium spur remaining at 90°-angle bend causing difficulty in forward negotiation of the stent.
