Prosthetic replacement of the superior vena cava after resection for malignant mediastinal tumour

The authors describe a case of malignant neoplasm of the mediastinum affecting the S.V.C. and the right lung. Radical removal of the neoplasm involved a right pneumonectomy and resection of the S.V.C. Replacement of the latter with a prosthesis in K Dacron double velour was successful--a success which has lasted 5 months to date.
