外周血管介入术中路径图的制作和应用研究

Study of Design and Clinical Application of the Roadmap in Peripheral Artery Interventional Procedure

目的研究制作一种更简单的路径图的制作方法和应用方法,达到实时修正插管方向的目的。方法通过10例典型的外周介入手术的应用,将常规得到的DSA造影图像作为蓝本,手工描绘或电脑自动检测出血管的走行和形态,利用坐标、线段、曲线、曲线边框或经过处理的造影血管图像等形式将其表现出来,再将它们作为插管参照物与实时透视影像进行重合或透明叠加后显示于同一个屏幕上,给选择性插管提供一个更加直观的路径指导。结果这种方法用在导丝进入血管分支的时候,可以起到显著的引导效果。结论这种路径图系统实现了指导介入插管的功能,是为了降低插管难度所进行的一种有价值的尝试。

Objective：To investigate a simple design and its clinical application of the roadmap in the interventional procedure of peripheral artery,in order to achieve a real time amendment of intra-arterial catheterization. Methods： In 10 typical cases,using routine digital subtract angiography （DSA） images as models, the course and morphology of blood vessels were manually or automatically traced. The vascular images were illustrated by coordinate, linear, curve or post-processed profile and was used as reference or roadmap. During trans-arterial catheterization operation, the reference roadmap and the real time images could be overlapped on the screen under fluoroscopy.more direct and accurate approach of selective transarterial catheterization could be obtained. Results：The function of above-mentioned roadmap system was obviously more effective in guiding the catheterized procedure especially when the guide-wire approached the branching of blood vessels. Conclusion： The roadmap system was an easy and valuable technique in the interventional trans-pcriphcral arterial catheterization procedure.
