title: Preassembled method for insertion of Ommaya reservoir.
abstract: OBJECTIVE
  Present a revised neurosurgical technique for insertion of the Ommaya reservoir that we have routinely utilized and found to have fewer complications that the standard approach.
  
  
  METHODS
  Randomized retrospective study of 20 patients who underwent insertion of Ommaya reservoir with the preassembled technique.
  
  
  METHODS
  Major university hospital.
  
  
  METHODS
  Twenty patients who underwent Ommaya reservoir placement within the last 5 years were randomly selected for chart and computed tomography review.
  
  
  METHODS
  A new preassembled technique for Ommaya reservoir placement was utilized in all 20 patients.
  
  
  METHODS
  Retrospective review of the patient records and computed tomography scans of 20 patients undergoing Ommaya placement were performed to assess ventricular catheter placement and any postoperative complications.
  
  
  RESULTS
  In all 20 patients, we had consistent ipsilateral right frontal horn placement of ventricular catheter and had no postoperative morbidities, reoperations for ventricular catheter positioning or mortalities.
  
  
  CONCLUSIONS
  This technique reduces overall operative time, decreases risk for intraoperative infection, and poor ventricular catheter placement by eliminating the manipulation step of connecting the reservoir to the catheter in vivo.
