Complications of stenting in superior vena cava syndrome / 中华放射学杂志

ABSTRACT

Objective To investigate the incidence and causes of complication of stenting in the treatment of superior vena cava syndrome (SVCS) for its proper prevetions. Methods Thirty nine patients with SVCS due to various diseases were retrospectively analyzed. The location, extension and degree of the stenosis were identified on venography before stent placement. Lumen narrowing becoming less than 50% or 20% improvement after stenting was taken as effective. Complications after stenting were analyzed. Results Thirty-five(89.7%, 35/39) patients relieved after stenting. Six patients (15.4%) had complications, including stents displacement due to mass lessened after chemotherapy in 1 cases, stents displacement and thrombogenesis due to lack of anticoagulant therapy and mass lessened after chemotherapy in 1 cases, restenosis due to mass growing into the screening of Gianturco Z-type stent in 1 cases, acute pericardial effusion in 1 cases, 1 of acute pulmonary embolism(PE) in 1 cases and acute congestive right heart failure and relieved after treatment in 1 cases. Conclusions Some complications of stenting in SVCS is serious. Proper procedure, stents selection and skillful handling can reduce the frequency of the complications.
