title: Utilization of the O-arm after Ommaya reservoir placement.
abstract: The authors demonstrate the utility of portable intraoperative CT scans for the rapid identification of ventricular catheter tip location after Ommaya reservoir placement. The O-arm (Medtronic Sofamor Danek, Memphis, TN, USA) was utilized to confirm ventricular catheter placement intraoperatively. Conventionally, a postoperative CT scan is obtained prior to Ommaya reservoir use to ensure proper catheter placement. By obtaining these images intraoperatively, revisions may be performed without the need for an additional surgical procedure, and the reservoir may be utilized immediately postoperatively.
