Chronic deep venous thrombosis (DVT) is defined by thrombus persisting beyond 28 days of initial onset and represents a condition that leads to long-standing venous hypertension, valvular incompetence, and ultimately chronic venous insufficiency and occlusion. As chronic thrombus organizes, it contracts and becomes adherent to the vein wall, causing scarring and consequent atresia of the lumen. The sequelae of such disease are manifested by limb edema, pain, discoloration, exercise intolerance, and ulceration—all encompassed within a clinical spectrum known as post-thrombotic syndrome. Attempts at recanalization with venoplasty and stenting of chronic inferior vena cava (IVC) and iliac occlusions are performed to restore the main venous outflow of the extremities to reverse or arrest the morbidity associated with this disease. This chapter discusses the interventional management of chronic iliocaval thrombosis.
