Pulmonary Embolus is caused by the clots in the circulatory system, from the right side of the heart. A Pulmonary Embolism can affect as many as 5 out of 10, 000 people in the U.S. per year! A sudden death can certainly occur from Pulmonary Embolus. If a patient wishes to avoid developing clots for the leg surgery, he should walk or engage in physical activities. Leg exercises would be of great help.

People get this condition pretty rarely. Some symptoms include coughing, in which they may have some blood in the saliva. After that they may experience shortness of breath, and splinting of ribs when trying to breath. Some people experience faintness and dizziness. Also, it can not be transmitted from physical contact.
