Society of Interventional Radiology position statement: treatment of acute iliofemoral deep vein thrombosis with use of adjunctive catheter-directed intrathrombus thrombolysis.

THE Society of Interventional Radiology (SIR) considers the use of catheterdirected intrathrombus thrombolysis (CDT) as an adjunct to anticoagulant therapy to represent an acceptable initial treatment strategy for carefully selected patients with acute iliofemoral deep vein thrombosis (DVT). The SIR defines acute iliofemoral DVT as complete or partial thrombosis of any part of the iliac vein and/or the common femoral vein with or without associated femoropopliteal DVT, in which symptoms have been present for 14 days or less or for which imaging studies indicate that venous thrombosis has occurred within the past 14 days (1).
