Primary head Injury

General

  • Found in 1.5– 3.0% of all head trauma
  • Predominantly in severe TBI.
  • Primary IVH
    • Incidence low
    • Referring to isolated bleeding confined to the ventricular system.

Pathology

  • Damage to the septum pellucidum, choroid plexus, and subependymal veins in the fornix are seen in post- mortem exams in patients with primary IVH.

Outcome

  • An estimated 21% of patients with IVH attain functional recovery (Glasgow Outcome Scale (GOS) moderate disability or good recovery) due to presence of concomitant intracranial injuries.
  • In infrequent cases of isolated IVH, more improvement in GOS is possible
  • In general, the small sample sizes make it difficult to interpret the specific prognostic significance of IVH as opposed to the associated TBI.
