Stereotactic removal of a migrating ventricular catheter

Retained ventricular catheters are usually well tolerated but, when infection is present, their removal becomes imperative because such catheters serve as a nidus for persistent infection. Minimally invasive methods for the removal of retained catheters are desirable. The removal of an infected, retained, subcortical ventricular catheter using stereotactic techniques is described. The authors think that this method is a safe and effective first step in dealing with this difficult problem.
