Neuronavigation device for stereotaxic external ventricular drainage insertion

Background The insertion of an external ventricular drainage (EVD) is one of the most frequently used neurosurgical procedures. It is performed to adjust intracranial hypertension in cases of severe craniocerebral injury, acute posthemorrhagic hydrocephalus, meningitis, and oncological diseases related to impaired circulation of cerebrospinal fluid circulation (CSF). Methods In 2020, three patients with subarachnoid aneurysmal hemorrhage underwent insertion of an EVD navigation percutaneous stereotaxic device. Three cases introduced. Results In all cases, satisfactory EVD functioning was noted during the surgery and during the early postoperative period. The EVD insertion procedure took an average of 10 min. The EVD insertion route calculations using the software took about 5-15 min. No cases showed any infection, hemorrhagic complications, or EVD dysfunction. According to the control brain computed tomography data, the catheter position was satisfactory and corresponded to the target coordinates in all cases. Conclusion The use of the device, with its high accuracy and efficiency, can reduce the incidence of unsatisfactory EVD implantation cases in patients with neurosurgical pathology.
