Inaccurate placement of external ventricular drains (EVDs) is a common issue in cerebrospinal diversion procedures. The conventional freehand technique results in a high fraction of sub-optimally placed catheters, and the use of image guidance can improve these results. The purpose of this paper is the validation of the use of an average model for guidance of EVD procedures.
Three neurosurgeons have tested the model-based technique on three normal volunteers, and we have compared the model-based technique to the freehand technique and neuronavigation based on volunteer-specific images.
Our results show that the surgeons perform significantly better when using the model-based technique than when using the freehand technique.
Our results suggest that the use of an average model may improve the accuracy of catheter placements. However, further refinement of the method and testing in a clinical setting is required.
在脑脊液分流手术中，外置脑室引流管（EVD）放置不准确是一个常见问题。传统的徒手技术导致相当一部分导管放置不理想，而使用图像引导可以改善这些结果。本文的目的是验证使用平均模型来指导EVD手术的可行性。
三位神经外科医生在三名正常志愿者身上测试了基于模型的技术，并且我们将基于模型的技术与徒手技术以及基于志愿者特定图像的神经导航进行了比较。
我们的结果表明，外科医生使用基于模型的技术时的表现明显优于使用徒手技术时。
我们的结果表明，使用平均模型可能会提高导管放置的准确性。然而，需要对该方法进行进一步完善并在临床环境中进行测试。
