Placement of a ventricular catheter into narrow lateral ventricles. Popular navigation

Abstract

The Thomale guide is a simple but reliable device for accurate and quick placement of a ventricular catheter into the lateral ventricles, regardless of their size.

Neuronavigation device for stereotaxic external ventricular drainage insertion

“…[2] Ventriculostomy is usually performed using the classic free hand technique described by Kocher et al methodology. [4] In the literature, the coordinates of the Kocher point differ, [5] which are confirmed by the spread of the overlap of milling holes and trephinations in our study [Figure 2]. e scatter of points for ventriculostomy in the premotor zone did not statistically affect the quality of EVD implantation.…”

“…In the literature, there are many modifications of the classical Kocher point, which, in some cases, can even improve the trajectory and accuracy of EVD implantation. [5] e number of unsatisfactory installation of EVD can reach 39% when using free hand technology. [6] In 1973, the experience of using the Gajar guide was published to improve the accuracy of the EVD installation.…”

“…[7] Since then, the literature has described a variety of mechanical and electronic devices capable of improving the accuracy of the direction of the EVD. [3][4][5]7] e advantages of the device proposed in this study are the provision of stereotaxic accuracy of the EVD insertion, which makes it possible to reduce the risk of an unsatisfactory catheter position, as well as the traumatization of the adjacent anatomical structures during the repeated EVD insertions "by hand. " Notably, the use of the device does not increase the risk of postoperative hemorrhagic or infectious complications.…”

Drug delivery in leptomeningeal disease: Navigating barriers and beyond

“…Some of the drawbacks of lumbar injection can be overcome through the Ommaya reservoir which is a neurosurgical implant used to deliver therapeutic agents directly into the intraventricular space. It requires an accurate placement of the ventricular catheter to reliably deliver the drug without any local toxicity of the drug or CSF leakage (Ozerov et al., 2014 ; Cohen-Pfeffer et al., 2017 ). By delivering the drug earlier in the course of CSF movement, the intraventricular route provides better drug distribution throughout the leptomeningeal space.…”
