Summary
Delayed intracranial hemorrhage (ICH) is rare in trauma patients on warfarin without initial ICH. Routine 24-hour repeat CT scans are unlikely to alter management for stable patients, suggesting initial imaging may suffice.
Area of Science:
- Trauma Surgery
- Neurosurgery
- Emergency Medicine
Background:
- Current guidelines mandate CT scans, observation, and repeat CT scans for warfarin patients with trauma.
- This practice persists despite evidence of rare delayed hemorrhage, even in mild traumatic brain injury without initial intracranial hemorrhage (ICH).
Purpose of the Study:
- To determine the incidence and outcomes of delayed intracranial hemorrhage (DICH) in trauma patients on supra-therapeutic warfarin without initial ICH.
Main Methods:
- Retrospective study of adult trauma patients on warfarin with INR >3 and no initial ICH on CT.
- Subsequent CT scans within 24 hours identified DICH; risk factors and outcomes were analyzed.
Main Results:
- Only 3 of 225 patients (1.33%) developed DICH.
- No statistically significant risk factors were identified due to low incidence.
- None of the patients with DICH required intervention.
Conclusions:
- Initial CT scan without ICH is adequate for trauma patients on supra-therapeutic warfarin.
- DICH is uncommon, and routine 24-hour reimaging is unlikely to change management in neurologically stable patients.
