Abstract

The accurate and safe delivery of a microcatheter to a targeted shunt pouch is essential for successful transvenous embolization of intracranial dural arteriovenous fistulas. However, complex anatomy and variations in head and neck veins and occluded sinuses can hinder intraprocedural microcatheter delivery. In this study, we introduce an intraprocedural flat panel detector rotational angiography and image fusion technique to aid precise navigation inside the veins and proper placement of the microcatheter in the targeted shunt pouch.

摘要

准确、安全地将微导管送达靶向分流囊对于成功进行颅内硬脑膜动静脉瘘的经静脉栓塞至关重要。然而,复杂的解剖结构以及头颈部静脉和闭塞窦的变化会阻碍术中微导管的输送。在本研究中,我们引入了一种术中平板探测器旋转血管造影和图像融合技术,以辅助在静脉内进行精确导航,并将微导管放置在靶向分流囊中。
