BACKGROUND: Ventriculoperitoneal shunting (VPS) is a common neurosurgical procedure used to treat hydrocephalus. Although the use of a navigation system in VPS achieves superior results compared with conventional surgery, the relationships among clinical symptoms, ventricular catheter placement, catheter obstruction, and the postoperative Evans index have not been clearly reported.
METHODS: We performed a retrospective study of 40 patients with VPS (the navigation surgery group) and 31 patients with VPS (the conventional surgery group). Clinical data, follow-up times, catheterization accuracy, postoperative outcomes, cumulative survival times, and correlations between catheter placement and obstruction, symptom grade and the postoperative Evans index were analyzed.
RESULTS: Thirty-seven patients experienced optimal ventricular catheter placement (grade 1), three experienced suboptimal placements (grade 2), and none experienced poor ventricular catheter placement (grade 3) in the navigation surgery group. Greater improvement in postoperative symptoms (p < 0.001), including less catheter readjustment (p < 0.001), was observed in the navigation surgery group. A Kaplan-Meier analysis showed that the cumulative catheter obstruction-free survival time was longer in the navigation surgery group (p = 0.016). Moreover, catheter placement was significantly correlated with catheter obstruction (p < 0.001). Additionally, catheter obstruction was significantly correlated with the symptom grade (p < 0.001) and postoperative Evans index (p = 0.002).
CONCLUSION: VPS for hydrocephalus via the occipital horn with a navigation system is superior to the conventional surgical procedure in terms of clinical outcomes, the precision of ventricular catheterization, and the occurrence of complications. Catheter obstruction-free survival times were longer in the navigation surgery group and catheter placement was significantly correlated with catheter obstruction.
