在动静脉畸形手术中，对血管结构的评估是制定好手术策略的关键。传统的二维数字减影血管造影(DSA)有时很难立体地了解AVM的结构。三维旋转血管造影术(3D-RA)为我们提供了更准确的信息，了解每个供血动脉、引流动脉和病灶之间的关系，但当AVM是由多个血管区域(如大脑中动脉和大脑后动脉)供应时，所有细节都不能在一幅图像中看到。对于手术模拟，病灶在脑内的位置也很重要，从而决定手术入路。最近的图像融合技术已经帮助外科医生创建了虚拟的外科领域，特别是在脑肿瘤[1-3]。本文介绍了3D融合图像在脑动静脉畸形手术中的应用，并对其临床应用进行了评价。
In AVM surgery, evaluation of angiostructure is essential to make a good surgical strategy. With conventional twodimensional digital subtraction angiography (DSA), it is sometimes difficult to understand AVM structure stereoscopically. Three-dimensional rotational angiography (3D-RA) gives us much more precise information about the relationships of each feeder, drainer, and nidus, but when the AVM is supplied by a multiple vascular territory (eg, middle cerebral artery and posterior cerebral artery), all the details cannot be seen in one image. For the surgical simulation, the location of the nidus in the brain is also important so as to decide the surgical approach. Recent image fusion technologies have helped surgeons create virtual surgical fields, especially in brain tumors [1–3]. In this article the authors introduced 3D fusion images in AVM surgeries and evaluated their clinical use.
