Insights

Surgical treatments for chronic subdural hematoma in elderly patients show similar outcomes, but twist drill craniostomy has higher early recurrence. Older patients (>80) face increased stroke risk and longer hospital stays with standard craniotomy.

Area of Science:

  • Neurosurgery
  • Geriatric Medicine
  • Neurology

Background:

  • Chronic subdural hematoma (CSDH) predominantly affects the elderly.
  • Elderly patients (>80) often receive less invasive procedures due to surgical risk concerns, despite limited evidence of benefit.
  • Surgical outcomes for CSDH in the elderly require further investigation.

Purpose of the Study:

  • To compare the efficacy and safety of different surgical interventions for CSDH in elderly patients.
  • To analyze practice patterns and outcomes across age groups (65-80 vs. >80 years).

Main Methods:

  • Retrospective analysis of patients aged 65+ undergoing surgical treatment for CSDH.
  • Surgical options included twist drill craniostomy (TDC), burr hole craniotomy (BHC), and standard craniotomy (SC).
  • Comparison of outcomes, demographics, and clinical data between patients aged 65-80 and those >80 years.

Main Results:

  • No significant differences in post-operative complications, overall outcomes, or late recurrence (30-90 days) were observed among TDC, BHC, and SC.
  • TDC demonstrated a significantly higher rate of recurrence within 30 days compared to BHC and SC.
  • Patients over 80 treated with SC experienced a higher risk of stroke and longer hospital stays.

Conclusions:

  • Twist drill craniostomy, burr hole craniotomy, and standard craniotomy yield comparable neurological outcomes in elderly CSDH patients.
  • Thick membranes in CSDH are a relative contraindication for TDC due to elevated 30-day recurrence rates.
  • Standard craniotomy in patients >80 is associated with increased stroke risk and prolonged hospitalization.
