Application to the development of computertechnology and operative instruments, stereotactic neurosurgery became more precise, and extended as its indication. CT-guided stereotatic aspiration of intracerebral hematoma is sperior operative procedure with rare complications. Using Stereotatic Aqua-Stream and Aspirator at the same time, hematoma was removed sufficiently. However, stereotactic neurosurgery had a major weak point, it was a blind operation. An endoscope (FVS-1000, M%M Co.) and SASA (Marui Medical Co.) wereapplied in 5 cases of intracerebral hematoma. In physiological saline, the endoscope had 32.9. angle of visual filed, 1mm-25mm depth of vision, and 16 pair/mm resolution. It was exellent ability for neurosurgery. Using for clinical cases, the bloody fliud in the hematoma cavity disturbed visibility. It was a difficult problem. Influence of bloody fluid concentration to depth of vision and resolution was investigated, and method of making clear visibility was described.
