As damage to the superficial cerebral venous anastomosis may create catastrophic complications even after successful surgery, it is important to visualize and determine the normal features of the venous anastomosis with computed tomographic angiography. A total of 90 patients underwent a 64-detector row helical CT scan of head. The superficial cerebral venous anastomosis was reconstructed by volume rendering, multi-planar reconstruction, and integral display algorithm. In particular, we examined the vein of Trolard, the vein of Labbe, and the vein of Sylvian, in order to analyze the venous anastomosis. The superficial cerebral venous anastomosis varied across different individuals, and in this study, six types of anastomosis were found. In 28 % of patients, no venous anastomosis was found in the unilateral cerebral hemisphere. The display rate of the vein of Trolard, the vein of Labbe, and the vein of Sylvian in contributing to venous anastomosis was 70, 80, and 91 %, respectively. The number of vein of Trolard and vein of Labbe on the left side was greater than that of those on the right side. We implemented the 64-detector row helical CT as a rapid and noninvasive method to investigate the superficial cerebral venous anastomosis in our group of patients. We performed substantial image processing for the visualization of the superficial cerebral venous anastomosis; this would not only enable the early diagnosis of cerebral venous disease, but also protect the cerebral vein during neurosurgical intervention.
由于即使手术成功，大脑浅表静脉吻合处的损伤也可能引发灾难性并发症，因此通过计算机断层血管造影术可视化并确定静脉吻合的正常特征非常重要。共有90例患者接受了头部64排螺旋CT扫描。通过容积再现、多平面重建和整体显示算法对大脑浅表静脉吻合进行重建。特别是，我们检查了Trolard静脉、Labbe静脉和大脑外侧裂静脉，以分析静脉吻合情况。大脑浅表静脉吻合在不同个体之间存在差异，在本研究中发现了六种吻合类型。在28%的患者中，单侧大脑半球未发现静脉吻合。Trolard静脉、Labbe静脉和大脑外侧裂静脉对静脉吻合的显示率分别为70%、80%和91%。左侧Trolard静脉和Labbe静脉的数量多于右侧。我们采用64排螺旋CT作为一种快速、无创的方法来研究我们这组患者的大脑浅表静脉吻合情况。我们对大脑浅表静脉吻合的可视化进行了大量图像处理；这不仅能实现脑静脉疾病的早期诊断，还能在神经外科手术干预期间保护脑静脉。
