Superior vena cava stenting.

Abstract

Treatment of SVC obstruction with metallic stents is a rewarding procedure. The patients have symptoms that are severe and debilitating and cause significant impairment of life-style. Stent placement rapidly alleviates the symptoms of SVC syndrome and improves the patient's quality of life. The long-term patency rates have not been established; however, in patients with SVC syndrome secondary to malignant disease, stents usually remain patent for the lifetime of the patient. Recurrences can be treated with further interventional radiographic techniques. Currently, because the long-term patency rates of SVC stents are not known, most interventional radiologists tend to treat SVC stenosis from benign causes with balloon angioplasty before placing metallic stents.
