Use of ultrasonic surgical aspirator (CUSA) in the treatment of intracranial tumors

CUSA is a newly developed operative device. It has three actions, namely fragmentation, irrigation and aspiration. Using GUSA, we have operated upon 14 patients with intracranial tumors since March 1985. The results are satisfactory. In the surgical reatment of intracranial tumors, the authors consider that CUSA has several obvious advantages: CUSA selectively pares major vessels; its use reduces damage on nearby issue; and it provides good visibi lity of the operating field.
