To introduce the new generation Candy-Plug II with a self-closing channel construction inside the plug.
The technique of the Candy-Plug II was demonstrated in a 50-year-old patient with residual chronic aortic dissection and thoracic false lumen aneurysm with false lumen backflow after open surgical repair of the ascending aorta for acute type A aortic dissection. The Candy-Plug Technique was applied in addition to a branched arch procedure using a new generation Candy-Plug II for false lumen occlusion. The Candy-Plug II is a short tubular stent graft with a small open channel inside the graft to accommodate the central cannula and allow retrieval of the dilator tip, which closes itself as soon as the dilator tip is removed. The channel inside the graft is unsupported and will collapse and thereby close. This new design obviates additional placement of a plug to occlude the midsection of the first-generation Candy-Plug. After deployment of the Candy-Plug, distal false lumen occlusion was confirmed on final angiogram and postoperative computed tomography scans without any leakage through the Candy-Plug.
The new generation Candy-Plug II is a useful refinement of the previously available model. It reduces the procedural steps and provides a longer sealing segment.
介绍新一代Candy-Plug II，其栓体内部具有自封闭通道结构。
在一名50岁患者身上展示了Candy-Plug II技术，该患者患有残留慢性主动脉夹层和胸段假性动脉瘤，在接受急性A型主动脉夹层升主动脉开放手术修复后存在假腔逆流。除了使用新一代Candy-Plug II进行分支弓手术以闭塞假腔外，还应用了Candy-Plug技术。Candy-Plug II是一种短管状支架移植物，移植物内部有一个小开放通道，用于容纳中心插管并允许取出扩张器尖端，一旦扩张器尖端被移除，通道会自行关闭。移植物内部的通道没有支撑，会塌陷从而关闭。这种新设计避免了额外放置栓塞来闭塞第一代Candy-Plug的中间部分。在部署Candy-Plug后，最终血管造影和术后计算机断层扫描证实远端假腔闭塞，且没有任何通过Candy-Plug的渗漏。
新一代Candy-Plug II是对先前可用模型的有益改进。它减少了手术步骤并提供了更长的密封段。
