A STUDY OF SUPERIOR VENA CAVA OBSTRUCTION SYNDROME.

Superior vena cava obstruction syndrome was studied in 22 patients with a view to assess the etiological pattern and clinical profile. It was found that 4 patients (18.1%) had benign disease and the remaining 18 (81.9%) patients had malignancy. In 13 patients (59.9%) obstruction occurred due to bronchogenic carinoma. No complications occurred with invasive diagnostic procedures. All heavy smokers (59.9%) were found to have malignancy. Normal lung fields on chest radiography and CT scan with superior vena obstruction syndrome suggested benign disease in 2 cases.
