Dual venous access approach for a long occluded segment. This case had occluded segment from right subclavian vein to right innominate vein. a Synchronized angiography of bilateral occluded ends showed occlusion length and site. b Blunt recanalization from both ends of the occluded segment was performed. c Guide wire was advanced via distal end of occluded segment and crossed occluded segment. d. Balloon pre-dilation was performed segment by segment. e Angiography showed successful recanalization after placement of two stents
