PULMONARY EMBOLISM

1. Venous thromboembolic (VTE) disease is the term that includes both deep venous thromboses (DVT) and pulmonary emboli (PE).

2. The majority of medically significant PEs are from from above knee DVTs (ileofemoral area). Most calf vein thromboses do not embolize.

3. Other sources of PE are upper extremity, internal jugular, and subclavian thrombi. Usually the source for the upper body thrombi are IV catheters, especially PICC lines.

4. PE is the 3rd most common cardiovascular cause of death (after ischemic heart disease and stroke).

5. In hospitalized patients, inadequate VTE prophylaxis is the usual cause of PEs.
