Twistdrill craniostomies are a safe neurosurgical technique with a low incidence of bleeding complications. Their use can be expanded beyond intracranial pressure monitoring to other procedures and settings.

Area of Science:

  • Neurosurgery
  • Surgical Techniques

Background:

  • Haemorrhagic complications of intracranial pressure monitoring (ICPM) are a concern.
  • Previous studies on ICPM techniques vary, limiting the use of twistdrill craniostomies due to fear of bleeding.

Purpose of the Study:

  • To prospectively evaluate the safety of twistdrill craniostomies.
  • To determine the incidence of haemorrhagic complications associated with the twistdrill procedure.
  • To assess the potential for expanding the clinical applications of twistdrill craniostomies.

Main Methods:

  • Prospective observational study.
  • 1032 twistdrill procedures performed on 941 patients between January 1994 and February 2001.
  • Data collected on patient demographics and complications.

Main Results:

  • Only 4 procedures (0.38%) resulted in clinically significant bleeds attributed to the twistdrill.
  • All bleeds were managed conservatively without surgical evacuation.
  • The study included patients aged 3 months to 93 years.

Conclusions:

  • Twistdrill craniostomies demonstrate a high safety profile.
  • The use of twistdrill craniostomies can be extended to other neurosurgical procedures.
  • Consideration should be given to using twistdrill craniostomies for ICPM in non-neurosurgical centers.
