Advancing appropriate microcatheters is essential for treatment. However, we still encounter inaccessible arterial branches because of the anatomical arrangement. While many successful techniques regarding microcatheters have been reported, there have been very few reports of microguidewire-shaping techniques. We developed the Simmons-Angled microguidewire INsertion to the Target (SAINT) technique for insertion of the microguidewire into inaccessible arterial branches. The SAINT technique is feasible for selection and insertion into arteries that are inaccessible with conventional methods.

Simmons 成角微导丝插入目标 (SAINT) 技术在神经血管内治疗中的应用

推进适当的微导管对治疗至关重要。然而，由于解剖结构的原因，我们仍然会遇到难以接近的动脉分支。虽然已经报道了许多关于微导管的成功技术，但很少有关于微导丝成形技术的报道。我们开发了 Simmons-Angled 微导丝插入目标 (SAINT) 技术，用于将微导丝插入难以接近的动脉分支。SAINT 技术对于选择和插入传统方法无法进入的动脉是可行的。
