We present 3 cases of unilateral internal carotid artery (ICA) occlusions with prominent single collateralizing vessel of vasa vasorum on computed tomographic angiography. The features on axial source and 3-dimensional images of computed tomographic angiography include "pseudostring sign," serpigenous course of the vasa vasorum, eccentric dot appearance in the wall of chronically thrombosed ICA, and termination in the neck or reconstituting into the ICA at or below the skull base.
我们报告3例单侧颈内动脉（ICA）闭塞病例，这些病例在计算机断层血管造影（CTA）上可见明显的单一血管滋养血管侧支循环。CTA轴位源图像和三维图像上的特征包括“假条索征”、血管滋养血管的蜿蜒走行、慢性血栓形成的ICA壁上的偏心点状表现，以及在颈部终止或在颅底或其下方重新汇入ICA。
