Collagen matrix was successful in cerebrospinal fluid containment in > 95% of patients requiring dural repair following anterior and posterior spinal surgery. Subfascial drains were safe. Routine lumbar drains are not required but are recommended for repair of established pseudomeningocele formations.

A case of interhemispheric subdural hematoma ( ISH ) is presented and discussed. This disorder is a rare form of intracranial hemorrhage, which classically presents as an isolated paresis of one leg or a hemiparesis worse in the leg than the arm. The majority of cases are due to occipital trauma because of the anatomy of the bridging veins. Chronic interhemispheric hematomas are rare since the natural history of these lesions is to spread out over the cerebral convexity. Conservative treatment for ISH may be beneficial unless neurological deterioration necessitates early operative intervention.
