目的：动静脉畸形（AVM）是一种难以治疗的病变，部分原因是难以形成病灶及其供血动脉、引流静脉和通道动脉的三维心理图像。我们的目的是开发个人计算机软件，允许更好地可视化复杂的，三维的，连接的血管解剖手术planning.METHODS：血管定义从磁共振血管造影和象征性地连接，形成血管树。AVM病灶也可通过磁共振血管造影确定。病灶和脉管系统的这些表示可以在软件程序中一起查看，该软件程序允许用户对血管组进行颜色编码或选择性地将连接的血管组“关闭”，以避免模糊用户想要观察的图像部分。可以从任何角度观察结构。血管也可以显示相交的任何磁共振血管造影片或叠加在数字减影血管造影片从同一patient.RESULTS：我们报告的结果，从两个病人的AVM中，我们的表示进行了比较，在手术过程中的结果。我们的三维血管树正确地描绘了病灶与供血血管的三维关系。我们发现，在额外的，未手术的病人，血管树创建的三维数字减影血管造影数据和体积渲染的原始dataset.CONCLUSION：计算机辅助，三维可视化复杂的血管解剖结构可以帮助在规划AVM的手术切除。产生这些图像的软件程序可以提供传统技术难以获得的重要信息。这种成像方法也适用于血管内手术和复杂肿瘤切除的指导。
OBJECTIVE: Arteriovenous malformations (AVMs) are difficult lesions to treat, partly because it is difficult to formulate a three-dimensional mental image of the nidus and its supplying arteries, draining veins, and arteries of passage. Our purpose is to develop personal computer software that allows better visualization of complex, three-dimensional, connected vascular anatomy for surgical planning.METHODS: Vessels are defined from magnetic resonance angiograms and are symbolically linked to form vascular trees. The nidus of the AVM is also defined by magnetic resonance angiography. These representations of the nidus and vasculature can be viewed together in a software program that allows the user to color-code groups of vessels or to selectively turn connected groups of vessels “off” to avoid obscuring the part of the image that the user wants to observe. Structures can be viewed from any angle. The vessels can also be shown intersecting any magnetic resonance angiogram slice or superimposed upon digital subtraction angiograms obtained from the same patient.RESULTS: We report results from two patients with AVMs in which our representations were compared with the findings during surgery. Our three-dimensional vascular trees correctly depicted the relationship of the nidus to feeding vessels in three dimensions. We show findings in an additional, unoperated patient for whom vessel trees were created from three-dimensional digital subtraction angiography data and compared with a volume rendering of the original data set.CONCLUSION: Computer-assisted, three-dimensional visualizations of complex vascular anatomy can be helpful in planning the surgical excision of AVMs. Software programs that produce these images can provide important information that is difficult to obtain by traditional techniques. This imaging method is also applicable to guidance of endovascular procedures and removal of complex tumors.
