We describe our preliminary experience using a road-mapping procedure that involves combining preacquired CTA with real-time fluoroscopy. This maneuver facilitates navigation in supra-aortic vessels from the arch to skull base levels. It requires less contrast than is used for traditional road-mapping while potentially reducing the hazard of thromboembolic events associated with direct catheterization. The accuracy of registration between the 2 volume datasets seems satisfactory for clinical practice.
我们描述了使用一种路线图绘制程序的初步经验，该程序涉及将预先获取的 CTA 与实时透视相结合。这种操作有助于在主动脉弓至颅底水平的血管中进行导航。与传统的路线图绘制相比，它需要的对比剂更少，同时可能降低与直接导管插入相关的血栓栓塞事件的风险。这两个数据集之间的配准精度似乎足以满足临床实践的要求。
