Abstract:
Objective To analyze retrospectively the clinical characteristics, pathogeny and therapy of traumatic interhemispheric subdural hematoma (ISH). Methods 31 ISH cases admitted since 1996 were reviewed and analyzed retrospectively concerning the clinical characteristics and therapies. Typically,ISH manifested itself with hemiplegia or monoplegia in the contralateral lower limb, called the falx syndrome, and unconsciousness was infrequent at the initial stage of the head injury. The pathogeny of ISH involved cracks of the bridging vein, hematomas in the interhemispheric small arteries and veins and probably coagulation dysfunction or anticoagulant therapy. Results In all 31 patients, 29 were cured and 2 died ofmultisystem organ failure (MSOF) and cerebral hernia respectively. The follow-up revealed that 6 cured patients developed interhemispheric subdural effusion. Conclusion CT scanning showing the interhemispheric hematoma exceeds 20 mL, or the interhemispheric hematoma is thicker than 1 cm can be referential to the diagnosis of ISH. For the ISH treatment, surgery and conservative management are suggested based on the functional disturbance or the stability of the disease. Patients with progressive neurologic deterioration should be operated without delay.
