Area of Science:

  • Neurosurgery
  • Medical Devices

Background:

  • External ventricular drainage (EVD) is a common neurosurgical procedure to manage intracranial hypertension.
  • Indications include severe head injury, hydrocephalus, meningitis, and brain tumors affecting cerebrospinal fluid (CSF) circulation.

Purpose of the Study:

  • To evaluate the efficacy and accuracy of a navigation device for percutaneous stereotactic EVD insertion.

Main Methods:

  • Three patients with subarachnoid aneurysmal hemorrhage underwent EVD insertion using a navigation device.
  • Procedure involved pre-operative route calculation and intraoperative navigation.

Main Results:

  • EVDs functioned satisfactorily in all cases during surgery and postoperatively.
  • Average EVD insertion time was 10 minutes; navigation planning took 5-15 minutes.
  • No infections, hemorrhagic complications, or EVD dysfunctions were observed. CT scans confirmed accurate catheter placement.

Conclusions:

  • The navigation device demonstrated high accuracy and efficiency in EVD implantation.
  • Its use can potentially decrease the rate of unsatisfactory EVD placements in neurosurgical patients.
