Abstract
Thymomas are rare mediastinum tumors with a low incidence rate, distinguished into types A, AB, B (B1, B2, B3), and C. Surgery is the essential treatment for patients with invasive thymoma. It is rare for thymoma to invade the right atrium (RA), the central airway, and the superior vena cava (SVC) simultaneously. Radical resection and Masaoka staging are the main prognostic factors for patients' long-term survival, and the survival rate is positively correlated with the degree of the thymoma resection. To ensure the patient's safety and a favorable prognosis. Adequate preparations and anesthesia management are indispensable. We would report the anesthetic management of a 20-year-old female student (166cm, 48kg, NYHA class III) with complaints of sudden palpitations accompanied by profuse sweating. The thymoma, located in the thymus area, with a vast invasion, was about 10cm*6cm*4cm. It had invaded the SVC, epicardium, part of the brachiocephalic trunk, transverse jugular vein, and main bronchi (squeezed and deformed), and the right lung and hilum were slightly affected on the upper and right side of the pericardium. This giant thymoma was entirely resected under general anesthesia and cardiopulmonary bypass (CPB). As a result, the anesthesia management of the giant thymoma undergoing radical resection was successful.
