Preclinical study testing feasibility and technical requirements for successful tele‐robotic long distance peripheral vascular intervention

Abstract

Background

Robotic‐assisted endovascular surgery enables us to perform interventions from long distances. This study evaluates the workflow and telecommunication requirements of tele‐robotic peripheral vascular interventions.

Methods

Ten superficial femoral artery cases were performed by the operator being 44 miles away from the interventional suite, with an endovascular robotic system, on a high‐fidelity endovascular simulator. Procedural success, technical success, fluoroscopy time, residual stenosis, contrast dose, and network delay were registered. Communication success was assessed after each procedure on a scale from 1(unacceptable) to 5(ideal).

Results

Procedural success and technical success were 100% and 80% respectively. The mean residual stenosis, fluoroscopy time, and contrast dose were 1.7±5.25%, 6.5±1.8 min, and 58.8±14.8 ml. The mean network latency was 38.9±3.5 ms. Median communication success scores were 4.5 (min: 4, max: 5) reported by both the operator and the bedside technician on a scale of 1 (unacceptable) to 5 (ideal).

Conclusion

With a stable network connection and good communication protocol, a high success rate was achieved for remote robotic‐assisted peripheral vascular intervention in an ex‐vivo model.
