Microvascular Doppler ultrasound-assisted neuroendoscopic surgery

achieve endoscopic procedures more safely and less invasively, an operative strategy with ultrasound-assisted neuroendoscopic surgery is described. Th e improvement in the endoscope unit is that endoscopic viewing can be stopp ed on the display, anytime we choose and simultaneously visualize the ongoi ng view on the same display. The ultrasound unit, using a miniature Doppler probe, is to able to detect even invisible vessels in real-time, easily an d non-invasively. The information from both units can be switched intraoper atively, whenever required.
