Preoperative computed tomography showed that the thymoma located in the anterior mediastinum (A) invaded the bilateral innominate veins, the superior vena cava, and the right atrium (B-D).

Computed tomography demonstrated a mass in the anterior mediastinum, measuring 13 cm x 7 cm, which was suspected of invading the SVC and the right atrium ( Figure 1 ).
During the operation, the tumor was observed to invade the superior vena cava and the right atrium together with the bilateral innominate veins, the right internal jugular vein, the right subclavian vein, the azygos vein, and the lung (A). The tumor was completely resected, and the venous bypass was established between the left innominate vein and the right atrium (B). Tumor specimen (C).

Through a median sternotomy, the tumor in the anterior mediastinum was observed to invade the SVC and the right atrium together with the bilateral innominate veins, the right internal jugular vein, the right subclavian vein, the azygos vein, and the lung ( Figure 2A ). Therefore, the right atrium was partially resected, and the tumor was removed entirely, followed by the venous bypass reconstruction between the left innominate vein and the right atrium ( Figures 2B, C ).
Postoperative X-ray (A) and computed tomography (B) imaging of the patient.
