Anticoagulation is generally accepted as the primary therapy for thromboembolic disease. Venous interruption proximal to the site of venous thrombosis is usually reserved for patients who have recurrent pulmonary emboli despite well-controlled, adequate anticoagulation; those who have a large, life-threatening embolus such that an additional one might be fatal; those who cannot be anticoagulated because of potential bleeding problems or other contraindication for anticoagulation; or those who are developing progressive pulmonary hypertension from repeated emboli.
