To report a new facilitated method for securing target vessel access during single fenestrated and branched thoracic endovascular repair using a guidewire fixator.
The Liungman Guidewire Fixator (LGF) includes a 0.035-inch guidewire that is fitted with a stopper close to the distal end and a self-expanding anchoring element that is freely movable over the guidewire to the point of the stopper. The technique of using a LGF for anchoring in a target vessel is described in a 75-year-old woman with a 53-mm saccular arch aneurysm. She was treated with a fenestrated Zenith stent-graft that had a catheter-preloaded fenestration for the left subclavian artery (LSA) and a scallop for the left common carotid artery. To avoid through-and-through wire and brachial access, the LGF was used to secure the guidewire in the LSA during stent-graft deployment.
The use of an LGF for anchoring in the target LSA during fenestrated arch endografting was feasible and safe.
报告一种新的辅助方法，用于在使用导丝固定器的单开窗和分支胸主动脉腔内修复术中固定靶血管。
Liungman 导丝固定器（LGF）包括一条 0.035 英寸的导丝，其在靠近远端的位置配备有一个止动器，以及一个可自由移动到止动器位置的自扩张锚固元件。在一位 75 岁女性患者中描述了使用 LGF 进行靶血管锚固的技术，该患者患有 53 毫米的囊状弓部动脉瘤。她接受了一种开窗型 Zenith 支架移植物治疗，该支架移植物具有用于左锁骨下动脉（LSA）的导管预装开窗和用于左颈总动脉的扇贝形结构。为了避免贯穿式导丝和肱动脉入路，在支架移植物置入过程中使用 LGF 将导丝固定在 LSA 中。
在开窗型主动脉弓内支架移植物置入术中，使用 LGF 锚固靶血管 LSA 是可行和安全的。
