Warfarin use in patients with chronic subdural hematoma (CSDH) does not worsen outcomes. This study found no increased risk or adverse events, suggesting warfarin can be restarted post-surgery.

Area of Science:

  • Neurosurgery
  • Hematology

Background:

  • A common perception is that patients with chronic subdural hematoma (CSDH) on warfarin fare worse.
  • Warfarin is an anticoagulant medication used to prevent blood clots.

Purpose of the Study:

  • To investigate the perception that warfarin use negatively impacts CSDH patient outcomes.
  • To determine the influence of warfarin on CSDH incidence, severity, and treatment outcomes.

Main Methods:

  • Retrospective analysis of CSDH patients treated between 1990-1992 and 1995-1997.
  • Comparison of outcomes between patients taking warfarin and those not taking warfarin.
  • Assessment of adverse events and recurrence rates.

Main Results:

  • The proportion of CSDH patients on warfarin increased from 11.8% to 20% between the study periods.

  • No significant differences were observed in age, sex, or comorbidities between warfarin and non-warfarin groups.
  • No adverse events or increased recurrence rates were associated with warfarin use in CSDH patients.

    • Conclusions:

    • Despite an increase in warfarin use among CSDH patients, warfarin does not adversely affect treatment outcomes.
    • Temporary cessation of warfarin for CSDH treatment did not lead to adverse events.
    • Recommencing warfarin 3 weeks after surgical evacuation of CSDH is suggested for anticoagulated patients.
