RF Wire Recanalization of Central Venous Occlusion MUSC (2008-2011): 42 patients with symptomatic CVO or SVC syndrome in whom conventional endovascular techniques failed Successfully crossed 43/43 lesions (up to 10 cm) 40/42 patency & asymptomatic at 6, 9 months\ One major complication: cardiac tamponade Journal of Vascular and Interventional Radiology , Volume 23 , Issue 8 , 1016 - 1021
RF Wire Recanalization of Central Venous Occlusion Tufts (2007-12): Technical success in 9/13 vessels (69%); 9/12 patients Length of occlusion smaller in successful (30 mm) vs unsuccessful cases (90 mm); (p 0.03) One major complication (tracheal perforation)
RF Wire Recanalization of Central Venous Occlusion Tufts (2013-present): Technical success in 10/10 vessels (9/9 patients) No major complications Take-home: In carefully selected patients, technical success may approach 100%
