Patients With Post-thrombotic Syndrome Are More Likely to Undergo Venographic Reintervention and Experience Slower Symptom Resolution After Iliac Vein Stenting

Abstract

Patients undergoing iliac vein stent placement (IVS) for chronic proximal venous outflow obstruction are observed to have two types of stenosis: a more focal stenosis from external compression, also known as nonthrombotic iliac vein lesions (NIVL), or more diffuse stenosis suggestive of post-thrombotic syndrome (PTS) from a remote deep venous thrombosis (DVT). We assessed the influence of PTS on the outcomes of IVS.
