Abstract | OBJECTIVE: The purpose of this article is to retrospectively evaluate the technical and clinical outcomes of large-bore nitinol stents for treating malignant superior vena cava syndrome. In addition, we analyzed factors potentially influencing the outcome. MATERIALS AND METHODS: RESULTS: Technical success was obtained in all but one patient (99%), who presented with a stent migration immediately after insertion. In 17 patients (22%), an additional balloon-expandable stent was needed for complete expansion of the nitinol stent. For patients with symptomatic malignant lymphadenopathies or primary lung tumor, overall survival rates were 50% (n=8) and 54% (n=34), respectively, at 6 months and 19% (n=3) and 34% (n=21), respectively, at 12 months (p=0.376). There was no difference in survival as a function of the Kishi score (p=0.80) or of the placement of an additional balloon-expandable stent (p=0.35). Finally, reocclusion events were noted in patients both with (n=1) and without (n=7) a balloon-expandable stent. CONCLUSION:
