  • Title: Management of symptomatic chronic extra-axial fluid collections in pediatric patients.
    Author: Litofsky NS, Raffel C, McComb JG.
    Journal: Neurosurgery; 1992 Sep; 31(3):445-50. PubMed ID: 1407427.
    Abstract:
    The records of 103 pediatric patients having symptomatic chronic extra-axial fluid collections treated at Children's Hospital of Los Angeles from 1977 to 1988 were reviewed. Patients were treated with observation, serial percutaneous needle drainage, drainage through burr holes, drainage into a closed external drainage system, or subdural to peritoneal shunt. If the initial treatment was not effective, additional forms of treatment were instituted. Shunts, ultimately used in 73% of the patients, proved to be the most effective treatment. Of the group with shunts, the extra-axial fluid was unilateral in 20% and bilateral in 80%. In those patients with bilateral effusions, no difference in efficacy of shunts was seen in patients treated with bilateral versus unilateral shunts. Of the 75 patients with shunts, 12% required a shunt revision for progressive or recurrent symptoms. Shunt infections occurred in 3% of the patients, necessitating removal of the shunt and treatment with antibiotics. Eosinophilia in the subdural fluid was associated with shunt obstruction requiring revision. The shunt was never removed in 51% of patients with no untoward effects. This study demonstrates that the most efficacious treatment of symptomatic chronic extra-axial fluid collections in children is a unilateral subdural to peritoneal shunt. The shunt need not be removed after resolution of the fluid collections.
