Venous thromboembolism covers two conditions, deep venous thrombosis and pulmonary embolism. They sound ominous, and they are.
Blood clots will form in the leg's deep veins, in deep venous thrombosis (DVT), causing pain and swelling. If a clot breaks off, and goes into the lungs, this is a pulmonary embolism. And it can be a very dangerous condition indeed.
The patient may experience shortness of breath and chest pain. In the most serious case, blood pressure may be dangerously low and the patient will not survive.
