Mechanical thrombectomy for DVT.

Deep venous thrombosis is a common source of morbidity and mortality in the United States. Complications include pulmonary embolism and chronic post-thrombotic syndrome. Chronic post-thrombotic syndrome is characterized by extremity pain, edema, venous claudication, skin changes, and skin ulceration. This syndrome is attributed to venous obstruction and valvular damage due to thrombus. The standard treatment of deep venous thrombosis consists of medical management with anticoagulation. Anticoagulation has proven efficacy in prevention of thrombus extension, pulmonary embolus, and re-thrombosis. The role of anticoagulation in post-thrombotic syndrome is unclear. Aggressive endovascular techniques for managing DVT have evolved as a result. Catheter-directed thrombolysis was the first such procedure with demonstrated efficacy, however its acceptance has been limited by perceived risks, time to lysis, and cost. As a result, alternative measures for managing DVT have evolved including mechanical thrombectomy. Mechanical thrombectomy for DVT has the potential to shorten the time for lysis, reduce the risk of thrombolytic agents, and potentially impact cost savings.
