The Feasibility, Accuracy and Safety of Robot-Assisted Ventriculoperitoneal Shunt.

OBJECTIVE

Ventriculoperitoneal shunt (VPS) treats hydrocephalus effectively, but manual ventricular catheter placement has a high misplacement rate. This study assesses the feasibility, accuracy, and safety of robot-assisted VPS.

METHODS

A retrospective analysis was performed on the clinical data of 87 patients from 2022 to 2024, with 42 receiving robot-assisted VPS and 45 receiving conventional manual VPS. Logistic regression analysis was performed to identify risk factors affecting placement accuracy.

RESULTS

The robot-assisted cohort showed smaller bilateral frontal horn diameters and a lower Evans index (p<0.05). It achieved higher placement accuracy, required fewer puncture attempts, and had a lower postoperative complication rate (p<0.05). No significant difference was found in operation time (p>0.05). Logistic regression analysis confirmed robot-assistance as a key factor for accurate catheter placement (odds ratio, 6.52; p<0.001).

CONCLUSION

Robot-assisted VPS achieves precise placement, reduces puncture attempts and complications, and does not increase time costs, confirming its clinical feasibility, accuracy, and safety.
