Objectives:In hydatid disease, the central nervous system is affected approximately in 2% to 3% of patients. Surgical management in these patients is important. To develop a surgical technique to avoid the formation of great volume of cavity after hydatid cyst removal and prevent complications associated with brain collapse and cortical convolution.Patients and Methods:In 2 patients, hydatid cysts were delivered by this new technique. A balloon filled with 150 cc of sterile air/distilled water was placed in the cavity until the balloon filled the entire cavity. Air/distilled water evacuation was continued at a rate of 20cc/d and, after a week, eventually, the balloons were removedResults:All cysts were delivered without rupture. Neurologic outcomes were good. No complications were observed related to usage of the system such as balloon rupture, evacuation problems, and infection.Conclusion:The authors believe that the balloon insertion technique may be a useful method to prevent brain collapse, cortical convolution, and complications associated with this condition. Further technical refinements of the system are needed for better results.
