Deep Vein Thrombosis (DVT) treatment
DVT’s are treated by administering anticoagulants (blood thinners) such as heparin or warfarin. Patients are generally started on heparin for immediate anticoagulation, and then continued on warfarin for 6 weeks to 6 months. Patients who are anticoagulated for 3 to 6 months have roughly on half the DVT recurrence rate of those who are anticoagulated for only 4 to 6 weeks. Anticoagulants are contraindicated in patients with active bleeding or bleeding disorders. These patients may benefit from placement of a Greenfield filter in the inferior vena cava. By placing a filter in the vessel which returns blood from the legs, any thrombi are screened out before they can get lodged in the vessels of the lungs.
