title: Intraoperative ultrasound as guide for neurosurgical endoscopic procedures.
abstract: A high-tec ultrasound-guided device for neurosurgical endoscopy is described. Intraoperative ultrasound is used to bring a 6 mm rigid endoscope tube to a wanted target area. Repeated ultrasound imaging control provides a survey of intracerebral structures surrounding the endoscopically approached operation cavity. The endoscope harbours a suction irrigation system for aspiration of lobar intracerebral, intraventricular and cerebellar hematomas. Moreover, a 0.6 mm Neodym YAG laser tube and various microinstruments allow the biopsy and resection as well as laser irradiation of ventricular and cystic intracerebral tumors. A miniaturised TV-camera attached to the endoscope's ocular allows continuous visual control over surgical procedures. This procedure has been experienced in 105 patients as a low risk intervention with minimal surgical trauma.
