Area of Science:

  • Neurosurgery
  • Medical Devices

Background:

  • Emergency neurosurgical interventions like ventriculostomy are critical for conditions such as acute hydrocephalus and ventricular hemorrhage.
  • Existing ventriculostomy methods necessitate standardization, speed, and minimal infection risk for effective emergency treatment.

Purpose of the Study:

  • To introduce a novel external ventriculostomy set designed for rapid, safe, and reliable emergency neurosurgical procedures.
  • To evaluate the efficacy and safety of this new ventriculostomy system in clinical practice.

Main Methods:

  • Development of a new external ventriculostomy set comprising a self-biting threaded screw, a metal cannula, and a specialized screwdriver.
  • Standardized procedure allowing for ventriculostomy placement within 2 minutes.
  • Rigid fixation of the system to the patient's skull for extended periods (up to several weeks).

  • Facilitated cannula exchange within 1 minute.

    • Main Results:

    • The developed ventriculostomy system enables rapid procedure times, with placement achievable in under 2 minutes.
    • The system allows for secure, rigid fixation to the skull for up to several weeks.
    • Cannula exchange is efficient, taking approximately 1 minute.
    • In a series of 90 cases, the system demonstrated a low infection rate of 1.1%.

    Conclusions:

    • The novel external ventriculostomy set offers a standardized, rapid, and minimally invasive solution for emergency neurosurgical conditions.
    • The system's design facilitates quick placement and secure fixation, reducing procedural time and potential complications.
    • The low infection rate observed in clinical use supports the safety and efficacy of this new ventriculostomy approach.
