Acute Subdural Hematoma

Acute Subdural Haematoma


  • Routine CTA should be performed in all patients presenting with an aSDH associated with SAH and no clear history of trauma.[ncbi.nlm.nih.gov]

  • Although DEH occurring after evacuation of ASDH or acute EDH is a rare event, timely recognition is critical to prognosis.[ncbi.nlm.nih.gov]
  • These results suggest that the presence of microbleeds and CH on MR images may indicate poor prognosis in patients with acute SDH.[ncbi.nlm.nih.gov]
  • Although good recovery tended to be observed less frequently in the bleeding tendency group than in the control group, the mean age of the bleeding tendency group was significantly higher than that of the control group, so the prognosis might be affected[ncbi.nlm.nih.gov]
