Stereotactic aqua stream and aspirator for removal of intracerebral hematoma.

The stereotactic aqua stream and aspirator is modified from the aqua stream and aspirator for stereotactic evacuation of intracerebral hematoma. The newly designed needles were adapted to Leksell, Patil, Komai and Sugita stereotactic equipment. The new device was used in 14 cases with intracerebral hematoma. The tips of the needles were stereotactically inserted into the center of the hematoma cavities. The ratios of evacuated hematoma against hematoma content varied from 73 to 98%, averaging 87.2%. Hematomas could be satisfactorily and safely evacuated at any stage. Cerebral perfusion pressure was increased by 20 mm Hg during surgery.
