The system consists of a multi-axis robotic C arm and surgical OR table. In addition to conventional neuroendovascular procedures, the system was used as an intraoperative imaging tool for various neurosurgical procedures such as aneurysm clipping or spine instrumentation.Results 501 neurosurgical procedures were successfully conducted in the hybrid OR using robotic DSA. During surgical procedures such as aneurysm clipping or arteriovenous fistula treatment, intraoperative two-dimensional/three-dimensional angiography and C arm based CT images (Dyna CT) were easily performed without moving the OR table. In addition, newly developed virtual navigation software (i-guide) can be used in the frameless navigation and access to deep seated intracranial lesions or needle placement.Conclusion The newly developed robotic DSA system provides safe and precise treatment in the field of endovascular treatment and neurosurgery.
