Answer

Percutaneous transcatheter treatment of patients with deep venous thrombosis (DVT) consists of thrombus removal with catheter-directed thrombolysis, mechanical thrombectomy, angioplasty, and/or stenting of venous obstructions. Consensus has been reached regarding indications for the procedure, although it is based on midlevel evidence from nonrandomized controlled trials. The goals of endovascular therapy include reducing the severity and duration of lower-extremity symptoms, preventing pulmonary embolism, diminishing the risk of recurrent venous thrombosis, and preventing postthrombotic syndrome. A randomized controlled trial comparing catheter-directed thrombolysis to conventional anticoagulation demonstrated a lower incidence of postthrombotic syndrome and improved iliofemoral patency in patients with a high proximal DVT and low risk of bleeding.
