To assess the effectiveness of endovascular stenting for the palliation of superior vena cava (SVC) syndrome, endovascular stent insertion was attempted in 10 patients with symptomatic occlusion of the SVC. All the patients had known malignant disease of the thorax. Eight patients had been treated previously with chemotherapy and radiotherapy (n=5), chemotherapy alone (n=2), or pneumonectomy and radiotherapy (n=1). After developing SVC syndrome, all the patients were stented before receiving any other treatment. After single or multiple endovascular stents were inserted, five of eight patients were treated with chemotherapy and radiotherapy (n=2) or chemotherapy alone (n=3). Resolution of symptoms was achieved in nine patients within 72 hr (90%). In one patient, the symptoms did not disappear until a second intervention. At follow up, symptoms had recurred in two of ten patients (20%) after intervals of 15 and 60 days. Five patients have died from their cancers, although they remained free of symptoms of SVC occlusion until death. In conclusion, endovascular stent insertion is an effective treatment for palliation of SVC syndrome. Endovascular stent insertion can be considered the first choice of treatment, due to the immediate relief of symptoms and excellent sustained symptomatic relief.
