We report a case of a 45-year-old female with a history of chronic iliac vein and
inferior vena cava (IVC) occlusion, who presented with diffuse bilateral lower limb
edema and pain secondary to severe postthrombotic syndrome. Computed tomography and
digital subtraction angiography demonstrated reocclusion in the patient's previously
placed iliofemoral and IVC stents. Recanalization was achieved with a percutaneous
endovascular bypass approach after unsuccessful attempts using standard and other
advanced endovascular techniques including sharp needle and radiofrequency wire recanalization.
