cavogram

— Note the penetration of the filter struts through the caval wall (arrowheads) (B) Simultaneous balloon angioplasty of the filter cone (arrows) and the previously deployed bilateral iliac Wallstents (C) Wallstents extended cephalad through the filter rings (arrows) in a double-barrel technique (D) Completion cavogram shows patent stents and resolution of the thrombus (A) Cavogram through a left femoral access demonstrates extensive thrombosis of the cava (arrows) below the preexisting suprarenal Trapease filter (arrowheads) (B) Digital subtraction cavogram shows widely patent Wallstents extending to the level of the filter (arrowheads) Comparison of time to re-intervention and patency between clinical success and clinical failure groups The primary goal of endovascular treatment was to achieve anatomical and clinical success.
