 | | Pulmonary emboli are caused by clots from the venous circulation, from the right side of the heart, from tumors that have invaded the circulatory system, or from other sources such as amniotic fluid, air, fat, bone marrow, and foreign substances. |
 | | The risk factors include prolonged bed rest or inactivity, oral contraceptive use, surgery, child birth, cancer, stroke, heart attack, heart surgery, and fractures of the hips or femur. |
 | | Early detection and treatment of DVT (clots of the legs) of patients who are at risk by early walking and activity after surgery can reduce the risk for pulmonary embolus. |
