Treatment for deep vein thrombosis typically includes the use of anticoagulant medications, also called blood thinners, which prevent clots from getting bigger and reduce the likelihood of future clots, states Mayo Clinic. In life-threatening situations, doctors sometimes use an IV to administer thrombolytic drugs that break up clots.
If blood thinners and thrombolytic drugs are unsuccessful, doctors may insert a vena cava filter to catch blood clots and prevent them from traveling to other parts of the body, according to WebMD. In rare cases, doctors perform venous thrombectomy surgery to cut out a deep vein clot. Wearing compression stockings helps prevent swelling in the lower legs and reduces the likelihood of clotting, notes Mayo Clinic.
