Endovascular treatment of superior vena cava obstruction in patients with malignancies

The aim of this study was to report our experience on the management of superior vena cava obstruction (SVCO) secondary to malignant disease, using endovascular procedures. Twenty-six patients with SVCO due to primary or secondary tumors of the lung or the mediastinum, or catheter inserted for treatment of an extra-thoracic neoplasm, had an endovascular therapy which consisted of stenting. angioplasty, thrombo-aspiration or local fibrinolysis. Immediately after the procedure, rapid relief of symptoms occurred in 24 (90 %) of the patients. The mean Kishi's score decreased from 5.5 to 0.96. Immediate complications included one death related to pericarditis bleeding following fibrinolysis. Three patients relapsed after 20 days, 4 months and 6 months, and needed a second stenting. At 6 months the:primary patency rate was 83 % and the secondary patency rate was 89 %, Endovascular treatment of SVCOs : is a simple and safe procedure to restore the patency of the superior vena cava in malignant SVCO. It should be indicated in most cases as first-line treatment and performed as early as possible.
