The purpose of this study was to determine the ability of software-assisted 3D reconstruction performed using a neuronavigation system to delineate the anatomy and variation patterns of the pineal region venous complex, and then to compare these data with previous anatomical findings.
The authors retrospectively reviewed the neuroimages obtained in 100 patients with intracranial lesions (50 computed tomography [CT] scans obtained with contrast agents and 50 magnetic resonance [MR] images obtained with gadolinium) by using a neuronavigation workstation for 3D reconstruction. Particular attention was given to the internal cerebral vein, basal vein (BV), and the vein of Galen. The various connection patterns between the major vessels were classified and statistically analyzed.
The venous system of the pineal region shows a wide range of sex-related variations. In the female patient the absence of a BV (Type 0) is significantly more frequent than in the male. In this study the authors illustrate the ability to depict the venous drainage patterns in the pineal region for all cases studied by using 3D neuronavigation software without the need for additional examinations. This simple tool provides important information for surgical planning and may be of significant help intraoperatively.
本研究旨在确定使用神经导航系统进行软件辅助三维重建描绘松果体区静脉复合体的解剖结构和变异模式的能力，然后将这些数据与既往解剖学研究结果进行比较。
作者回顾性分析了100例颅内病变患者的神经影像资料（50例使用对比剂的计算机断层扫描[CT]和50例使用钆剂的磁共振[MR]图像），通过神经导航工作站进行三维重建。特别关注大脑内静脉、基底静脉（BV）和大脑大静脉。对主要血管之间的各种连接模式进行分类并进行统计学分析。
松果体区静脉系统存在广泛的性别相关变异。在女性患者中，BV缺如（0型）的发生率明显高于男性。在本研究中，作者展示了使用三维神经导航软件描绘所有研究病例松果体区静脉引流模式的能力而无需额外检查。这个简单的工具为手术规划提供了重要信息，并且在术中可能有很大帮助。
