Stereotatic implantation of Ommaya reservoir in the management of brain abscesses

We evaluated the effectiveness of computed tomography (CT)-guided stereotatic implantation of Ommaya reservoir in the management of brain abscess. Forty-five patients with brain abscesses were treated with CT-guided stereotatic implantation of Ommaya reservoir and followed up between September 1998 and February 2008. The Glasgow Outcome Scale (GOS) was use to evaluate the effectiveness of the Ommaya Reservoir treatment. The GOS score at 3-months post-operation was 5 for 41 patients (91.1%), 4 for 2 patients (4.4%) and 3 for 2 patients (4.4%), respectively. The results suggest that the CT-guided stereotatic implantation of Ommaya reservoir is a potential technique that can be safely used to treat the brain abscess.
