[A case of malignant lymphoma of anterior mediastinum requiring superior vena cava reconstruction].

The patient was a 21-year-old female with malignant lymphoma of the anterior mediastinum, which was associated with superior vena cava (SVC) syndrome due to tumor invasion and tracheo-bronchial stenosis due to tumor compression. The bilateral brachio-cephalic vein and superior vena cava were resected with the tumor, and SVC reconstruction with a ringed expanded polytetrafluoroethylene (EPTFE) graft was performed between the right brachio-cephalic vein and SVC, and between the left brachio-cephalic vein and the right appendage. Postoperative anti-coagulant therapy was not performed. Postoperatively, SVC syndrome and the complaint of tracheo-bronchial stenosis disappeared promptly. Venography, which was performed 2 weeks postoperatively, presented patency between the right brachio-cephalic vein and SVC, but the graft between the left brachio-cephalic vein and the right appendage was obstructed. SVC reconstruction using a ringed EPTFE graft is considered to be significant for the improvement of resectability and the relief of clinical symptoms.
