Superior vena cava syndrome caused by invasive epidermoid carcinoma.

Lung cancer is the most frequent cause of superior vena cava (SVC) syndrome. Malignant SVC syndrome is generally considered a contraindication to curative resection, although palliative bypasses are done for symptoms that do not respond to medical therapy. However, a majority of patients with such advanced disease die of complications caused by the primary tumor rather than distant metastasis. We present the case of one patient with lung cancer invading the mediastinal structures. Combined resection and replacement of the SVC with a segment of Dacron vascular graft was performed. Postoperative survival time was 24 months.
