Endoscopic treatment of brain abscesses

Abstract

Background: Stereotactic aspiration with external drainage has become widely accepted as the standard treatment for intracerebral abscesses. Although neuroendoscopic technique has only been occasionally adopted for this pathology, it introduces some advantages because it presents visual awareness that the pus has been removed.

Methods: Four patients with cerebral abscess and one with a subdural empyema were operated using a neuroendoscopic technique in our Department between 1996 and 2003. A 4-mm flexible endoscope was introduced into the purulent collection through a burr hole, the pus was meticulously aspirated, and the cavity washed with isovolumetric antibiotic lavages using the working channel for both irrigation and suction.

Conclusion: Neuroendoscopic treatment of brain abscesses presents some additional advantages as a possible alternative to stereotactic aspiration, which still constitutes the gold standard for this pathology. The adoption of stereotactic or frameless guidance systems can probably be recommended particularly for deep, complex lesions.
