Objective:
To analyze the clinical characteristics, pathogenesis and management of traumatic interhemispheric subdural hematomas (ISH).
Methods:
Thirty-one traumatic ISH cases were reviewed and analyzed retrospectively.
Results:
Of the 31 patients, 29 were cured and 2 died of multi-system organ failure (MSOF) and cerebral hernia respectively. Typically, ISH manifested hemiplegia or paralysis of the counterlateral lower limb known as falx syndrome.
Conclusions:
CT scans showing hematocele in the interhemispheric subdural space in excess of 20 ml, or with a thickness of hematocele over 1cm, may serve as a diagnostic criteria for ISH. For the treatment of ISH, surgery and conservative management are suggested on the basis of functional disturbance or the stability of the disease.
