title: [Treatment of superior vena cava syndrome by metal stents. Preliminary experience].
abstract: This study was aimed at verifying the feasibility of stent placement in superior vena cava syndrome (SVCS). From April, 1993, to February 1995, fifteen patients (12 men, 3 women, age range: 48-72 years, average age: 58 years), were treated for malignant stenoses involving superior vena cava in 9 cases, right innominate vein in 3, left innominate vein in 2 and subclavian veins in 1. All patients had been submitted to CT angiography and digital venography to assess side, length and type of the stenosis. In 6 patients locoregional fibrinolysis (with urokinase) was performed. The stenosis was successfully dilated by balloon catheter and the stent was finally removed. Subclavian and innominate veins stenoses were treated with Wallstent, using brachial approach, while stenoses of superior vena cava required transfemoral catheterization for Gianturco-Rosch "Z" stent placement. A control venogram was performed after stenting, with the evaluation of pre/post stent pressure gradient, and later at 1, 3 and 6 months. The stents were positioned in all patients with immediate technical success; no major complications occurred. Two recurrences were successfully resolved. Radiation and/or medical therapy without vascular disobstruction showed worse results in the treatment of superior vena cava syndrome. The percutaneous placement of self-expandable stents should be not only the therapeutic alternative to surgery but the method of choice in these pathologic conditions.
