RÉSUMÉ
Objective To evaluate the clinical value of percutaneous transluminal angioplasty with stenting(PTAS) for the treatment of superior vana cava obstructive syndrome (SVCOS). Methods 15 cases of SVCOS including 10 cases of lung cancer with mediastinal lymphatic metastasis, 3 cases as malignant lymphoma and 2 cases of esophageal cancer with mediastinal lymphadenopathy, were undergone right subclavian vein or ellow vein catheterization for pressure measurement and DSA imaging of SVC with displaying the obstructive characteristics. A self expanding stent was then implanted throwgh right fermoral vein catheterization.Results 15 cases were all successfully undertaken angioplasty and stenting, except 1 case with a long stricture over 10 cm requiring 2 stents. After successful stent placement, DSA revealed smooth flow of contrast with almost normal diameter of SVC lumen, together with disappearance or relief of SVCOS. The SVC pressure decreased from 30.5?2.3 cmH 2O down to 8.8?1.5 cmH 2O after recanalization, with a significant difference in statistics( P
