Endovascular Treatment of Malignant Superior Vena Cava Syndrome: Is Bilateral Wallstent Placement Superior to Unilateral Placement?
2003
Purpose:To report our experience with unilateral versus bilateral stent placement in the treatment of malignant superior vena cava syndrome (SVCS).Methods:The records and films of 84 consecutive patients (69 men; mean age 64±10 years, range 39–79) referred for stent placement in malignant SVCS were reviewed for venous compromise, technical and clinical success, complications, and reocclusions. Wallstents were placed covering the SVC and both (bilateral technique) brachiocephalic veins (BCV) preferentially; unilateral stenting of only one BCV in addition to the SVC was performed based on operator preference or inability to access both sides. Technical success was defined as the ability to stent the SVC and at least one BCV; clinical success was the elimination of SVCS symptoms.Results:Technical success was achieved in 83 (99%) patients, using the unilateral technique in 22 and bilateral stenting in 61 patients. The groups did not differ with regard to age, sex, underlying diseases, or location and extent o...
