title: [Combined resection and replacement of the superior vena cava with an expanded polytetrafluoroethylene graft in surgery of pulmonary-mediastinal malignant tumor].
abstract: Combined resection and replacement of the superior vena cava with an expanded polytetrafluoroethylene graft was performed in 7 patients. Five patients had lung cancer, and 2 had malignant thymoma. During operation, total clamping of the superior vena cava was required in 2 patients, and partial clamping of the superior vena cava or clamping of the innominate vein in 5. The reconstruction procedures were as follows; the superior vena cava or bilateral innominate veins with a graft in 4 patients, bilateral innominate veins with 2 grafts in 1, and one of the innominate veins with a graft in 2. There was no operative death. Edema of face, neck and arms appeared in 6 patients postoperatively, but it disappeared in 3-10 days. Phlebogram which was obtained in 5 patients demonstrated patency of the grafts in 4 and well-developed collateral drainage in 1. Postoperative survival time was 1-27 months, and 3 patients are alive. No superior vena cava syndrome was recognized in long term observation of any patient.
