The purpose of this study was to present a new technique for endovascular aortic arch repair for 1, 2, or 3 vessels using preloaded wires and precannulated target vessels without wire wrapping.
This technique uses a prototype catheter with 2 parallel lumens to position through-and-through guidewires in the supra-aortic branches and an extra-stiff guidewire in the ascending aorta with no wrapping. This allows the introduction and advancement of the device with the already precannulated target vessels. The endograft is advanced to the aortic arch without twisting or wrapping. Covered stents are deployed to align the graft and target vessels.
To our knowledge, a technique that avoids wire wrapping has not been previously described. This technique allows safer and faster endovascular arch procedures and opens up new possibilities by enabling multi-vessel endovascular aortic arch repair with all precannulated target vessels.
本研究旨在介绍一种新的技术，用于在不进行线缠绕的情况下，使用预加载的导丝和预先套管的靶血管，对 1、2 或 3 个血管进行血管内主动脉弓修复。
该技术使用一种带有 2 个平行管腔的原型导管，将贯穿导丝定位在上主动脉分支中，并在升主动脉中使用超硬导丝，无需缠绕。这允许已经预先套管的靶血管引入和推进装置。移植物无需扭曲或缠绕即可推进至主动脉弓。覆盖支架的部署用于使移植物和靶血管对齐。
据我们所知，以前没有描述过避免线缠绕的技术。该技术可使血管内弓部手术更安全、更快速，并通过允许所有预先套管的靶血管进行多血管血管内主动脉弓修复，开辟新的可能性。
