Introduction: We analyzed the surgical results in patients operated for an arachnoid cyst evaluating the different surgical techniques employed, the average life of each procedure and the rate of postoperative complications. This study describes the results from our institution. Material and methods: We included all patients operated with a diagnosis of intracranial arachnoid cyst from January 2001 to December 2006. We evaluated the effectiveness of each surgical technique and the average life of each procedure, as well as adverse events associated with surgical treatment. Results: The gender distribution was 15 men and 13 women, with an average of 34 years and with a range of 17 to 65 years at time of surgery. The predominant symptom was headache. The location of the arachnoid cyst was 24 supratentorial and 4 infratentorial. 48 surgeries were performed. There were complications in 11 patients in the study group; the craniotomy was the procedure with a longer life (1245 days). The half-life of the craniotomy more fenestration was significantly higher than the rest of the procedures (853 vs. 193 days with a P: 0.0333) and the arachnoid cyst grade III of Galassi is a risk factor for reoperative in our study group with an odds ratio of 13,417. Conclusion: In our experience the fenestration by craniotomy was the procedure with fewer complications and increased time of effectiveness. Treatment complications are strongly related to cyst location and size.
