Robotic catheter ventriculostomy: feasibility, efficacy, and implications

Area of Science:

• Neurosurgery
• Medical Robotics
• Image-Guided Surgery

Background:

• Robotic applications offer potential benefits in surgery, including improved outcomes and reduced complications.
• Widespread adoption of robotic technology in neurosurgery remains limited.
• The study investigates the efficacy of robotic-assisted ventriculostomy catheter placement.

Purpose of the Study:

• To evaluate the safety, accuracy, and reproducibility of image-guided robotic placement of ventriculostomy catheters.
• To test the hypothesis that robotic placement is a viable and effective neurosurgical technique.

Main Methods:

• A retrospective study involving sixteen patients requiring ventriculostomy for ventriculoperitoneal shunt or reservoir placement.
• All patients underwent image-guided robotic placement of a ventricular catheter using a preoperatively defined trajectory.

Main Results:

• Successful single-pass catheter placement was achieved in all patients.
• No catheter-related hemorrhages or injuries to adjacent neural structures occurred.
• The mean distance of the catheter tip from the target was 1.5 mm, with significant reductions in operative times over the study period.

Conclusions:

• Robotic placement of ventriculostomy catheters is safe, accurate, and reliable.
• This technique facilitates single-pass ventriculostomy, even in patients with small ventricles.
• Robotic assistance allows for optimized trajectory planning, potentially minimizing risks to vascular structures.
