Cavitron Ultrasonic Surgical Aspirator

  • James S. Choi


Different techniques of liver parenchymal transaction have been described, including finger fracture, sharp dissection, clamp-crush technique, the hydrojet, and more recently, the Cavitron Ultrasonic Surgical Aspirator (CUSA). The CUSA is an innovative tool for dissecting through the liver parenchyma, which can potentially reduce intraoperative blood loss and perioperative morbidity. The CUSA system is a powerful ultrasonic aspirator and dissector with a wide application not only in liver surgery but also in other surgical specialties as well. The CUSA is widely used in multiple surgical subspecialties, including neurosurgery, gastrointestinal, hepatobiliary surgery, gynecology, and urology. CUSA Excel is an ultrasonic surgical aspirator, where fragmentation, suction, and irrigation occur simultaneously, allowing the surgeon to remove tissue with accurate control. In liver surgery, it is an invaluable tool, particularly in a situation where the tumor is closely adjacent to a vital structure that needs to be saved. CUSA will enable dissection around any structure that needs to be preserved.
