目的：探讨彩色编码血流图对颅内动静脉畸形（AVM ）术前及术中评估的价值。方法回顾性分析15例AVM患者术前行常规全脑DSA检查，并用iFlow软件进行影像后处理的彩色编码血流图的影像资料，在二维DSA图像及彩色编码血流图上对AVM的病灶范围、血管构筑及血流动力学等进行综合分析。结果15例AVM患者中，小型9例（其中4例畸形团表现为弥散型），中型3例，大型3例；单支供血动脉8例，多支供血动脉7例；单支引流静脉11例，多支引流静脉4例。在显示动静脉畸形团大小，尤其是弥散型畸形团方面，彩色编码血流图较二维DSA图像可更加清晰。彩色编码血流图能直观显示表浅和深部的引流静脉走形，同时根据曲线下面积大小和半峰宽长短，可以判断出主要引流静脉和次要引流静脉，并能直观反映脑血流的完整周期。结论彩色编码血流图可快速、准确地描绘出AVM的范围、血管构筑特征以及术中血流动力学的变化。

Objective To investigate the preoperative and intraoperative assessed values of the color-coded digital subtraction angiography (DSA ) for intracranial arteriovenous malformation (AVM). Methods Fifteen patients with AVM performed preoperative routine whole brain DSA were analyzed retrospectively,and the iFlow software was used to perform color-coded DSA of image post-processing. A comprehensive analysis such as the range of lesions,vascular architecture and hemodynamics of AVM was conducted on the two-dimensional DSA images and color-coded DSA. Results Of the 15 patients with AVM,9 were small-sized (including 4 nidi showed diffuse type),3 were medium-sized,and 3 were large-sized;8 patients had single feeding artery,and 7 had multiple feeding arteries;11 had single draining vein,and 4 had multiple draining veins. When showing the size of AVM nidus,particularly diffuse type nidus, the color-coded DSA was clearer than the two-dimensional image. The color-coded DSA could visually display the traveling of the superficial and deep draining veins,at the same time,the primary and secondary draining veins could be identified according to the size of the area under the curve and the full width at half maximum,and intuitively reflected the complete cycle of cerebral blood flow. Conclusion The color-coded DSA can quickly and accurately depict the range of AVM,angioarchitecture features and intraoperative hemodynamic changes.
