[Anesthetic management of a patient with Trousseau's syndrome and ovarian cancer who underwent gynecological surgery].

Trousseau's syndrome, a complex paraneoplastic disease, is characterized by the occurrence of thromboembolic disorders such as brain infarctions in patients with malignant neoplasms. We report the case of a 46-year-old woman with ovarian cancer who had suffered cerebral infarctions and presented with left hemiplegia, aphasia, and atypical genital bleeding. She suffered multiple right brain infarctions, a pulmonary embolism, a right renal infarction with bilateral hydronephrosis and deep venous thromboses and exhibited increased D-dimer and fibrinogen levels and so was administered heparin (10,000 U x day(-1)). She had no other underlying diseases such as coagulopathy, cardiovascular disease, collagen disease, or angiitis. Therefore, we were able to diagnose her with Trousseau's syndrome. She was scheduled to undergo total abdominal hysterectomy with bilateral oophorectomy, pelvic lymphadenectomies, and omentectomy. Preoperatively, an inferior vena cava filter was temporarily installed to prevent the development of further pulmonary thromboses. General anesthesia was uneventfully maintained by inhalation of oxygen, air, and sevoflurane and the continuous infusion of remifentanil whilst regional cerebral oxygen saturation and transesophageal echocardiography monitoring were performed. Postoperatively, she received heparin-based anticoagulant therapy (10,000 U x day(-1)) and did not exhibit bleeding diathesis or thrombosis. It is of great importance that anesthesiologists are aware of the thromboembolic status of patients with malignant neoplasms, especially those with gynecological tumors.
