[Percutaneous treatment of superior vena cava obstruction].

Endovascular therapies represent the most efficient treatment of benign or malignant obstructions of the superior vena cava. The indication of stenting in case of malignant obstruction depends on the severity of the superior vena cava syndrome, the histological type of the tumor, and the response to radiotherapy and chemotherapy. Restoration of the superior vena cava patency is obtained in more than 90% of cases, with persistent good mid and long term results. Complications are rare, especially after early treatment. Stenting of benign obstructions, especially in patients who undergo hemodialysis, allows to restore venous accesses. However, indication of treatment may be discussed because the initial and late patencies are lower than in malignant obstructions.
