球囊血管成形术和支架置入在靠近分支肺动脉分叉的位置可能是具有挑战性的。之前已经描述了多种方法，尽管这些方法都不能同时治疗双侧近端分支肺动脉狭窄，也没有一种方法能为经导管肺动脉瓣置换术提供依据。我们报告了一种新的方法，包括连续放置支架和通过每条肺动脉支架的支柱球囊扩张，同时将支架近端的球囊扩张到主肺动脉的直径。在我们描述的两个病例中，这种策略在不损害主肺动脉段解剖的情况下，显著缓解了分支肺动脉梗阻。该技术是缓解双侧肺近端分支狭窄的有效方法，并为未来的经导管肺动脉瓣提供了着陆区。©2015 Wiley期刊，Inc.
Balloon angioplasty and stent placement in close proximity to the bifurcation of the branch pulmonary arteries can be challenging. Multiple approaches have been previously described, though none of these approaches both treats bilateral proximal branch pulmonary artery stenosis and provides an anchor for a transcatheter pulmonary valve replacement. We report a novel approach that involves serial stent placement and balloon dilation through the struts of the stent in each pulmonary artery, along with balloon expansion of the proximal portion of the stents to the diameter of the main pulmonary artery. In the two cases we describe, this strategy resulted in significant relief of branch pulmonary artery obstruction without compromising the anatomy of the main pulmonary artery segment. This technique can be an effective way to alleviate stenoses of the bilateral proximal branch pulmonary arteries and provides a landing zone for a future transcatheter pulmonary valve. © 2015 Wiley Periodicals, Inc.
