Stereotactic aqua stream and aspirator for hypertensive intracerebral hematoma.
The stereotactic aqua stream and aspirator (SAS & A) is a modification of the aqua stream and aspirator (AS & A) designed for stereotactic evacuation of intracerebral hematoma. The needle of the new instrument is inserted into the brain through a burr hole by a conventional stereotactic technique and its tip is directed to the center of the hematoma. The hematoma is broken up with a stream of saline solution from a nozzle. Fragments of clot and fluid can then be aspirated piecemeal through the suction tube. The postoperative CT images show successful evacuation of the hematoma, and the clinical evaluation also showed satisfactory results. This instrument can be used safely, without any complications, early after the stroke.
