Summary

This study details a novel closed external ventricular drainage system using a Broviac catheter for prolonged cerebrospinal fluid management. The system demonstrated low infection rates and resistance to dislodgement in pediatric patients.

Area of Science:

  • Neurosurgery
  • Pediatric Surgery
  • Infectious Disease

Background:

  • Prolonged cerebrospinal fluid (CSF) drainage is often necessary for pediatric patients with conditions like CSF leaks or shunt infections.
  • Traditional external ventricular drainage (EVD) systems can be associated with risks such as infection and dislodgement.

Purpose of the Study:

  • To describe and evaluate a closed external ventricular drainage system incorporating a Broviac catheter with a dacron cuff.
  • To assess the safety, efficacy, and complication rates of this modified EVD system in pediatric patients.

Main Methods:

  • A closed EVD system utilizing a Broviac catheter was placed in 17 pediatric patients for 19 procedures.
  • Indications included CSF leak (1 patient) and shunt infection (16 patients).

  • Drainage duration averaged 19 days (range: 6-47 days).

    • Main Results:

    • The system was effective in managing CSF leaks and infections, with 13 of 16 infected patients eventually undergoing shunt placement.
    • The infection attack rate was low at 2.77 per 1,000 patient-catheter days.
    • Complications included ventricular catheter revision (4 cases) and system irrigation (4 cases); one secondary CSF infection occurred.

    Conclusions:

    • The Broviac ventriculostomy system offers a highly infection-resistant and stable option for prolonged CSF drainage in pediatric neurosurgery.
    • This modified EVD system appears to reduce the risk of infection and dislodgement compared to conventional methods.
