[Superior caval syndrome. Diagnostic and therapeutic management. Apropos of 20 cases].
Superior vena cava obstruction (SVCO) is an infrequent syndrome. Clinical diagnosis is often late. 20 cases of SVCO collected in 7 years are being reported. In 17 cases, SVCO revealed the underlying disease. It was mostly neoplastic (12 times), especially pulmonary cancers (5 times) and lymphomas (twice). Among benign causes (5 times), mediastinal fibrosis was the most often recognized (twice). Prognosis depended on etiology: when it was malignant, mortality rate was 50 p. cent (actuarial survival rate after one year: 40 p. 100); when it was benign, there was no mortality (follow-up: 21 months). Thrombo-embolic complications (25 p. 100) were seen during the end-stage of neoplasms and were responsible in 4 out of 7 deaths. Surgery was interesting for diagnosis (histology) and treatment (bypass surgery, the result of which was good only in the 3 operated benign causes). A simple model is proposed for treatment.
