Background: Carotid endarterectomy (CEA) is widely performed under operative microscopes. They provide magnified and stereoscopic vision of operative field suitable for precise maneuver. However, the microscope has some shortcomings, which are a narrow field-of-view, shallow depth-of-field, and the operator's fatigue due to fixed gaze posture through eyepieces. To overcome them, we introduced ORBEYE™ Surgical Microscope, which was 4K ultra high-definition three-dimensional (3D) system. We present our initial experience of the system for CEA and discuss its usefulness compared with the operating microscopes. Methods: A 66-year-old male presented to our department for the treatment of the left internal carotid artery severe stenosis. He underwent CEA using the ORBEYE™ Surgical Microscope. Results: The surgery was successfully completed only under the system without complication. The microscope was set over the operative field. Its wide field-of-view, deep depth of field, and smooth digital zooming allowed minimal repositioning of the microscope. The system provided high quality stereoscopic image of the surgical site, which enables us to perform precise surgery. The 55-inch 4K 3D monitor remarkably contributed to a reduction of the surgeons' fatigue. Conclusions: The ORBEYE™ Surgical Microscope, incorporating 4K 3D video technology, has overcome shortcomings of the operative microscope. This system is highly feasible for CEA and has the certain possibility for other neurovascular surgeries.
