Ct and MRI in the evaluation of ventriculo subgaleal technique for CSF diversion

ABSTRACT

The ventriculo-subgaleal technique for C.S.F. drainage was applied to 60 patients included in this study with acute hydrocephalus of variant etiologies. All patients were evaluated before and after shunt by CT and MRI to assess the degree and cause of hydrocephalus. The value and efficacy of V.SG Drainage Technique was verified both clinically in terms of Glasgow Coma Score in 93.3% and radiologically using the ventricular size index on serial CT scans in 95% of the cases. The V.SG.D replaced the external drainage for periods as long as 3 weeks with no risk of infection and lesser costs. 20% of the patients in this work proved to be shunt independent and V.SG.D has efficiently curved its temporary purpose during the acute phase of hydrocephalus. It also proved its reliability until a definite corrective surgery was performed
