Neuroendovascular Training Using Multisource Video-Recording System in a Hybrid Operating Room.

Abstract

Increasing restrictions over trainees' working hours and the recent coronavirus disease 2019 pandemic warrant new educational methods of surgical skills. We assessed a novel video-recording system for neuroendovascular skill education, developed with the installation of a hybrid operating room (OR) at our institution. A single-plane angiography unit with a large flat display (FlexVision XL; Philips Medical Systems) was installed in our OR. All media sources in the OR, including live fluoroscopy and ceiling-mounted camcorders, were connected to a video switcher. This video switcher laid up to 8 video images into one big image, which was transferred to the large display and the professional-use Blu-ray recorder. The recording was performed continuously during the procedure. This recording system was evaluated retrospectively with a questionnaire administered to the 5 trainees. Using this system, 68 interventional procedures were recorded. Among the potential merits, the trainees assigned the greatest value to the simultaneous recording of the operator's hand motions and the fluoroscopy images. Among the potential limitations of the system, the prolonged time and the increased volume of the video data bothered the trainees the most. The recorded video looked like a live demonstration. Our "selfie" video recording system was useful for skill training of neuroendovascular interventions.
