Study of superior vena cava syndrome--aetiopathology, diagnosis and management.

Thirty two patients of superior vena cava syndrome (SVCS) were studied. Clinical features noted were diffuse neck swelling, breathlessness, chest pain, engorged neck veins, facial swelling and dilated engorged veins over chest wall. Radiography revealed a superior mediastinal mass in 31.2% of patients and right upper lobe mass in 50% patients. FNAC of lung showed aetiology in 34.5% patients and lymph node biopsy in 31.2% patients. Aetiology of SVCS was benign in 12.5% patients and malignant in 87.5% patients. Squamous cell carcinoma was the commonest cause of SVSC. Radiotherapy proved to be the most beneficial form of treatment. The mean survival period in patients due to malignant etiology was 6 months.
