Causes - Pulmonary Embolism
Pulmonary embolism is a serious potential complication of DVT in which a blood clot has traveled to the lungs, an organ that utilizes numerous blood vessels of various sizes to oxygenate the blood. If a blood clot travels here and becomes lodged, it can cut off critical blood flow, resulting in severe tissue damage, shock, heart failure, or even death.
Blood clots in the upper thigh are more likely to travel to the lungs than those in the lower leg.
Symptoms of Pulmonary Embolism
If you or someone you know has a history of DVT, or is at risk for it, call 911 immediately if these symptoms occur:

- increased heart rate or respiration
- sudden cough or coughing up blood
- wheezing, difficulty breathing
- fainting, light-headedness, dizziness, or loss of consciousness
