The use of a self-expanding metallic stent (SEMS) for the treatment of superior vena cava (SVC) syndrome arising from non-neoplastic mediastinal disease is controversial, and data on long-term clinical observations for such have not yet been accumulated. We report a case of fibrosing mediastinitis with an obstruction of the SVC 30 months after the insertion of an SEMS. The patient had a headache and temporal facial swelling when the obstruction occurred, but these symptoms disappeared within 1 month. No further treatment was required in this case.
