Introduction: Introduction: Endoscopic method is an alternative to shunt placement and open surgery; it creates a communication between cyst, ventricular system and subarachnoid system.
Aim: To describe the demographic, clinical profile, operative technique, complications and outcome following endoscopic management of intracranial arachnoid cysts at a tertiary Care Hospital in Southern India.
Materials and Methods: A retrospective observational study was conducted in tertiary care hospital in southern India in which case records of all 42 symptomatic patients diagnosed with intracranial arachnoid cyst and who underwent surgical management by endoscopic techniques from 1995 to 2010 were included. Demographics, clinical presentations, type of surgery, complications and clinical outcome were recorded and results were expressed in terms of frequency and percentages. The data was entered in Microsoft excel was imported to IBM SPSS version 20.
Results: Study included 30 males and 12 females with a mean (SD) age of 14.8 (15.5) years. The most common presenting feature was raised intracranial pressure (38.1%). Cysts were commonly located in posterior fossa (31.0%) followed by intraventricular region (26.2%). All patients (100%) underwent endoscopic fenestration with either cystoventriculostomy or cystocisternostomy. Endoscopic Third Ventriculostomy (ETV) was done in 21.4% of patients associated with hydrocephalus. Postoperative complications (11.9%) included Cerebrospinal Fluid (CSF) leak, subdural hygroma and metabolic complications. Mortality rate was 2.4%. Follow-up period ranged between 1-99 months (median 24 months). Success rate of the procedure was 95%.
Conclusion: Prevalence of intracranial arachnoid cyst is common in males and is often located in the posterior fossa. The endoscopic management of intracranial arachnoid cyst is safe and is associated with superior clinical outcome.
