Key Points

To validate the safety and efficacy of the YDHB-NS01 robotic system for cerebral angiography and review robotic technology in neurointerventions.
Enrolled 50 patients total, with 25 receiving robotic-assisted and 25 manual cerebral angiography.
Evaluated primary endpoints: technical and clinical success rates.
Measured secondary endpoints: procedure time, fluoroscopy time, radiation dose, contrast volume, and complication rate.
Conducted a literature review on robotic systems in neurointervention.
Achieved a 100% technical success rate for both groups.
Robotic-assisted procedures had a significantly shorter average time (27 vs. 38 minutes).
No complications or malfunctions were reported with the robotic system.
No significant differences in fluoroscopy time, radiation dose, contrast volume, or total room time between the two groups.

Abstract

Abstract Background To validate the clinical safety and efficacy of a domestically produced robotic-assisted system (YDHB-NS01) for cerebral angiography and to review the current status, advantages, and challenges of robot-assisted technology in cerebrovascular interventions. Methods From May to October 2025, 25 consecutive patients who underwent robotic-assisted cerebral angiography and 25 consecutive patients who underwent manual cerebral angiography at our center were prospectively enrolled. The primary endpoints were technical success rate and clinical success rate. Secondary endpoints included procedure time, fluoroscopy time, radiation dose, contrast volume, total angiography room time, device performance evaluation, and complication rate. Additionally, a literature review was conducted to summarize the applications and developments of various robotic systems in neurointervention. Results All 50 (25 in the robotic-assisted group and 25 in the manual group) procedures were successfully completed with a 100% technical success rate. There were no differences between the two groups in patients’ demographic data, fluoroscopy time, patient radiation dose, contrast agent dose, or total angiography room time (all p > 0.05). The robotic-assisted group had a shorter procedure time than the manual group (27 15, 143 vs. 38 21, 105, p = 0.005). A learning curve for the robotic-assisted system was observed. The robotic-assisted system operated stably without malfunctions. No procedure-related or device-related complications occurred. Conclusion The preliminary clinical application demonstrates that the YDHB-NS01 robot-assisted system is feasible for diagnostic cerebral angiography and shows early indications of safety and comparable procedural performance to those of conventional manual methods. Given the small, single-center cohort and the exploratory nature of this study, larger multicenter controlled trials are required to confirm these findings.
