Unless there is some kind of really rare vascular abnormality in the lung, the clots don't form there but move there from other places., most commonly the legs.

In addition to prolonged immobilization of the legs, like taking a long flight, clots can form as a result of taking medication, most commonly birth control pills, especially if one smokes as well. Smoking itself increases the risk of blood clots, and some people are born with coagulation disorders that only can be identified after they are investigated following their first episode of clotting. One can get clots in association with some autoimmune diseases, such as Lupus, and as well, very rarely, abnormal clotting can be a manifestation of underlying malignant disease.

One of the causes of blood clots in a person's lungs is known as the pulmonary embolism which is the blockage of the main artery of the lung or one of its branches by a substance that has travelled from elsewhere in the body through the bloodstream.

What effect does coagulation has on health?

Coagulation is the process of blood forming clots. Blood that is essentially too "thick" may form clots within the body leading to a stroke, heart attack, or blood clots in places like the lungs or legs. If a patient is put on an anti-coagulant or "blood-thinner" it reduces the time in which the blood coagulates thus helping to prevent these clots.

Blood clots can become stuck in any small blood vessels, however the most serious places for clots to lodge are the brain (causing ischaemic stroke), the coronary arteries of the heart (causing a heart attack) or the lungs (pulmonary embolism).

Is fibrillation dangerous?

Atrial fibrillation (A-fib) is a very dangerous condition. In A-fib, the heart is trying to pump too fast, but is uncoordinated. This means that blood is not circulated around the body well. It also causes blood to swirl around inside the heart and can lead to forming blood clots. If one of these blood clots goes to the lungs it can cause a pulmonary embolis, or if it goes to the brain it can cause a stroke, both of which could be deadly.

What life threatening complications can develop from thrombophlebitis?

The big threat are blood clots which might move to critical locations such as the brain or lungs.

What is a pulmonary embolism?

A pulmonary embolism is a blood clot in the lung. Clots that form elsewhere in the body can become lodged in the blood vessels leading from the right ventricle to the lungs.

What are antithrombotic stockings?

These are elastic stockings which exert a set amount of pressure on one's legs. This helps blood return through the veins towards the heart. They prevent blood clots from forming when the blood pools in the legs and coagulates. The danger is that these blood clots could cause a pulmonary embolism (a clot blocking the blood supply to the lungs).

What is the medical meaning of antiphospholipid syndrome?

Antiphospholipid syndrome is a type of autoimmune disease. It causes clots to form much more easily. This leads to deep vein thrombosis, stroke and clots in organs like the lungs or kidneys.
