Abstract
Chronic obstruction of the iliac veins or inferior vena cava can occur as a result of deep vein thrombosis, or owing to extrinsic compression in nonthrombotic iliac vein lesions (NIVLs). This obstruction can manifest as post-thrombotic syndrome (PTS) after deep vein thrombosis or as chronic venous disease (CVD) in NIVL. Little evidence exists to support the use of deep venous stents in established PTS or NIVLs, and the evidence for its use in the prevention of PTS is inconclusive. A provisional health economic analysis over 5 years found that the incremental cost-effectiveness ratio of stenting versus no stenting over a 5-year period was between £7,500 and £52,000 per quality-adjusted life-year for treatment of established PTS.
