摘要

当左锁骨下动脉（LSA）被覆盖时，建议在胸椎血管内主动脉修复（TEVAR）中同时开窗进行血运重建。然而，由于LSA解剖的成角性，鞘对中缺乏准确有效的定位方法。我们开发了一种新的鞘对齐方法，其特点是引导导管的前部连接(j)与移植支架和降主动脉。它形成一个弯曲的牵引系统，将穿刺针拖到LSA孔的中心。137例患者随访9.0个月（4.0 ~ 17.5个月），无内漏率93.8%。未观察到再干预或死亡率。我们的鞘对准方法可以安全地在LSA开窗中进行，简化了手术程序，并有助于避免医源性并发症。

A Novel Sheath Aligning Method of Left Subclavian Artery Revascularization in TEVAR.

Concomitant left subclavian artery (LSA) fenestration is recommended in thoracic endovascular aortic repair (TEVAR) for revascularization when the LSA is covered. However, the sheath alignment lacks an accurate and efficient positioning method due to the angulation of LSA anatomy. We developed a novel method for sheath aligning characterized by the guiding catheter's front junction (J.) with the graft stent and descending (D.) aorta proceeding. It forms a curved traction system that drags the puncture needle to the center of LSA orifice. A 93.8% endoleak-free rate was observed during the 9.0 (4.0-17.5) months follow-up in 137 patients. No reintervention or mortality was observed. Our sheath aligning method can be safely performed in LSA fenestration, which simplifies the surgical procedure and may help to avoid iatrogenic complications.
