Use of an inflatable balloon on a catheter to prevent subdural fluid collections after intraventricular tumor surgery: technical note.

Ventricular tumor surgeries pose significant challenges to the neurosurgeon. Apart from the operative challenges and typical complications of surgery, subdural fluid collection is common after these surgeries. Various methods have been used to prevent this complication. The authors' technique of implanting an inflatable balloon attached to a catheter after resection of a huge intraventricular tumor was highly effective in preventing the development of a subdural fluid collection.
