[The palliative treatment of venous stenoses in tumor patients with self-expanding vascular prostheses]

Abstract

During 53 months 14 patients with tumour-induced obstructions of the superior vena cava (n = 8), the inferior vena cava (n = 2) and iliac veins (n = 4) were treated with self-expandable metallic stents. 21 Wall stents and 5 Gianturco double stents were applied. The follow-up lasted from 2 weeks to 16 months (range = 5.7 months). All patients showed a marked relief of inflow obstruction after stent placement. 6 of 7 patients, who died of their disease during follow-up, were asymptomatic regarding vein obstruction until their death (3 weeks to 16 months). In 6 of 7 still living patients no re-obstruction occurred during follow-up (2 to 16 months). Patency rate was 82%. These results suggest that self-expanding stents are a successful palliative therapy of malignant vein obstructions.
