The purpose of this study was to describe the use of a wire and catheters embedded with optical fiber (Fiber Optic RealShape [FORS]) to catheterize tortuous target vessels avoiding radiation.
A virtual biplane vies was simulated coupling traditional x-ray system, preoperative CT scan, and FORS system to treat an isolated hypogastric aneurysm. Despite the complex anatomy, catheterization of all target vessels was possible in 12 minutes with 19 seconds of fluoroscopy time (Radiation Exposure 3.8 mGy×cm). A minimal invasive endovascular exclusion of the aneurysm was achieved through selective coil-embolization of the iliolumbar artery and implantation of balloon expandable covered stents, thus preserving the perfusion of the superior gluteal artery.
FORS guidance allowed catheterization of a target vessel with challenging anatomy with a low radiation exposure.
本研究旨在描述使用带有光纤的导丝和导管（光纤真实形状[FORS]）在避免辐射的情况下对迂曲的靶血管进行导管插入。
通过模拟虚拟双平面，将传统 X 射线系统、术前 CT 扫描和 FORS 系统相结合，治疗孤立性髂动脉瘤。尽管解剖结构复杂，但通过 19 秒的透视时间（辐射暴露 3.8 mGy×cm），在 12 分钟内即可对所有靶血管进行导管插入。通过对髂腰动脉进行选择性线圈栓塞和植入球囊扩张式覆膜支架，实现了对动脉瘤的微创血管内隔绝，从而保留了臀上动脉的灌注。
FORS 引导可实现对具有挑战性解剖结构的靶血管进行低辐射暴露的导管插入。
