Area of Science:

  • Neurosurgery
  • Medical Devices
  • Clinical Trials

Background:

  • Continuous external cerebrospinal fluid (CSF) drainage is a standard neurosurgical procedure.
  • Technical advancements aim to improve the safety and efficacy of CSF drainage.
  • A novel screw fixation device was evaluated in a prospective study.

Purpose of the Study:

  • To assess the safety and efficacy of a new screw fixation device for needle trephination in patients requiring external CSF drainage.
  • To evaluate the learning curve associated with the new device and procedure.

Main Methods:

  • A prospective study involving 212 needle trephinations in 165 consecutive patients.
  • The procedure utilized a new self-tapping cannulated screw fixation device.
  • Procedures were performed at the bedside under local anesthesia using a twist drill.

Main Results:

  • The mean operative time was 6 minutes.
  • 91% of ventricular needles were accurately placed on the first attempt.
  • The main indications were intracranial pressure (ICP)-monitoring and -therapy (88%).
  • Complications included 2% intracerebral hemorrhages and 8% infections.

Conclusions:

  • The new ventriculostomy device offers significant advantages, including being time-saving and having an optimal fixation system.
  • The device facilitates uncomplicated needle exchange in cases of obstruction.
  • A learning curve was observed regarding infection, fixation, and surgical handling, indicating areas for procedural refinement.
