Simple method improving the accuracy of puncture in anterior ventricular access of EVD--based on radiological data of Chinese adults

Abstract

Abstract Background: In our clinical work, we sometimes find that the classic technique of anterior ventricular access of EVD is not accurate, so we use simple method to improve its accuracy. Methods: Using a standard axial computed tomography scan of cranium on viewing system (any slice and any distance between two points can be measured easily when we needed), we locate some projections and other sites that we need on topogram(scanogram), then locate them on patients' scalp. Combining their locations above, we want to verify the shortcoming of classic technique of anterior ventricular access of EVD and to improve it. Results: The study demonstrates that there are some shortcomings in the classic technique of anterior ventricular access of EVD, we can get a more accurate result via a simple method in our practice. Conclusions: Using a simple method, we can improve the accuracy of the technique of anterior ventricular access of EVD.
