Abstract

Ventriculo-peritoneal shunt placement is a common neurosurgical procedure for hydrocephalous. VPS failure rates have been estimated at approximately 11–25% within the first year especially in pediatric patients.An eight year old boy with Dandy Walker syndrome post VPS presented with complains of headache and progressive loss of vision for the past 10 days. Vision in RE – 5/60 and LE – CFCF. Fundus examination:NO papilloedema. CT showed shunt tube was in-situ with arachnoid cyst. VEP- prolonged P100 latency so a trial of Intravenous Methylprednisolone was given. But patient dint improve .Vision deteriorated to BE-PL+PR+. VP shunt exploration done and found to malfunctioning. shunt revision was done. 2 months after the procedure , vision in RE improved to 6/60 and LE HM with mild temporal pallor. High index of suspicion for shunt failure should be there in cases presenting with other symptoms and signs of increased ICT even in the absence of papilloedema.
