Background: Ventricular catheter placement can be a challenging procedure when treating patients with slit ventricles, despite the use of a neuronavigation system.
Methods: We report the case of 3 patients with idiopathic intracranial hypertension who had required revision of their ventricular catheter due to malpositioning, despite initial placement using neuronavigation. Owing to the absence of intraoperative computed tomography in our center, we used the O-arm imaging system to confirm placement of the optimal ventricular tip position intraoperatively.
Results: Optimal ventricular drain position was achieved in all 3 patients.
Conclusions: This short technical note describes an easy technique for using the O-arm to confirm the optimal ventricular drain position.
Keywords: Hydrocephalus; O-arm; Ventriculoperitoneal shunt.
