Anesthetic management of a patient with giant retroperitoneal liposarcoma: case report with literature review.

Patients with giant retroperitoneal liposarcomas are considered at great risks of perioperative complications and require meticulous anaesthetic management. There have been few reports about anaesthetic management of giant retroperitoneal liposarcoma. We present the case of a 66-year-old patient who suffered from a giant retroperitoneal liposarcoma (diameter 45 cm and weigh 4.5 kg), needing a resection surgery under general anesthesia. We successfully managed anesthesia procedures in this patient using FloTrac/Vigileo(TM) monitoring system without major perioperative complications. The surgery was completed uneventfully and the patient recovered smoothly. After reviewing the literature, we summarize FloTrac/Vigileo(TM) monitoring system is useful to help anaesthesiologists adjust infusion rate to maintain the stability of circulatory state. Anesthetic monitoring, fluid management and temperature control need to be focused in the anesthetic management.
