Introduction Robotic assisted neurointervention is a recently available technology with exciting future applications in the treatment of neurovascular diseases.
Aim of Study To evaluate the effectiveness and safety of robotic platform Corpath GRX (Siemens Healthineers Endovascular Robotics, Newton, MA, USA) for treating cerebral aneurysms alongside 6 months clinical follow-up.
Methods This prospective, international, multi-center study enrolled patients with clinical indication for endovascular coil and/or stent-assist coiling embolization. The primary effectiveness was defined as successful completion of the robotic-assisted endovascular procedure absent any unplanned conversion to manual. An independent clinical evaluation committee assessed outcomes gathered over the course of six months post-procedure.
Results The study enrolled 117 patients among 10 international sites, with mean age of 56.6 years and 74.4% females. Headache was the most common presenting symptom in 34.2% subjects. Internal Carotid Artery was the most common location (27.9%) and the mean aneurysm height and neck width were 5.7±2.6 mm and 3.5±1.4 mm respectively. Primary effectiveness was achieved in 94% (110/117) subjects with seven subjects requiring conversion to manual procedure. Only 4 primary safety events were recorded with 2 intraprocedural aneurysm ruptures and 2 minor strokes. Raymond Roy Classification Scale of 1 was achieved in 94.1% (96/102) subjects at 6 months follow-up, with mRS of ≤2 for 98.9% (87/88) subjects.
Conclusion This trial affirms the efficacy and safety of robotic-assisted cerebral aneurysm treatments, and serves as a steppingstone towards the potential future application of building on the current technological platform for achieving the goal of remote thrombectomy.
