Endoscopic treatment of intraventricular cerebrospinal fluid cysts: 10 consecutive cases.

INTRODUCTION

The use of the endoscope for lesions of the central nervous system has been progressively widened in the past decades. Among these lesions, the intraventricular cyst is one of the most attractive targets for this less invasive procedure.

METHODS

Between 2003 and 2007, ten consecutive patients with IVC underwent endoscopic surgery in our department. The location of the cyst was the lateral ventricle in nine, the lateral and third ventricles in one. The cyst was resected or fenestrated according to the degree of adhesion of the cyst wall with the ventricular wall. The follow-up ranged from 6 months to 54 months (mean: 22.5 months).

RESULTS

The cyst was totally removed in three, subtotally removed in one, and fenestrated in six cases. Except for transient fever, there was no post-operative morbidity. During follow-up, all patients were doing well.

CONCLUSION

The endoscopic technique is a good treatment option with the advantage of minimal invasiveness and less complications. The extension of the cyst and whether the hemisphere involved is dominant or not, determines the ideal endoscopic trajectory. The long-term efficacy of the endoscopic technique in treatment of IVC needs further evaluation.
