Pulmonary Embolus Treatment
Emergency treatment and hospitalization are necessary. In cases of severe, life-threatening pulmonary embolism, definitive treatment consists of dissolving the clot with thrombolytic therapy. Anticoagulant therapy prevents the formation of more clots and allows the body to re-absorb the existing clots faster.
Thrombolytic therapy (clot-dissolving medication) includes streptokinase, urokinase, or t-PA. Anticoagulation therapy (clot-preventing medication) consists of heparin by intravenous infusion initially, then oral warfarin (Coumadin). Subcutaneous low-molecular weight heparin is often substituted for intravenous heparin in many circumstances.
In patients who cannot tolerate anticoagulation therapy, an inferior vena cava filter (IVC filter) may be placed. This device, placed in the main central vein in the abdomen, is designed to block large clots from traveling into the pulmonary vessels. Oxygen therapy may be required to maintain normal oxygen concentrations.
Surgery in patients at great risk for recurrent embolism is sometimes indicated.
