Venous Thromboembolism is the blood clot in the vein. It is related to two life-threatening conditions:
Deep vein thrombosis; is a clot in a deep vein, usually in the leg.
Pulmonary embolism; is a DVT clot that breaks free from a vein wall which travels to the lungs and blocks some or all of the blood supply. A Blood clot present in thigh is more likely to travel to the lungs than blood clots in the lower leg or other parts of the body.
Blood clots form when due to some reason there is slows or changes in the flow of blood in the veins. These clots can form in, or travel through the arteries or veins in the brain, heart, kidneys, lungs and limbs. They may cause heart attack, stroke, and damage to the body organs or even resulting death. Clotting is more likely to happen in the people who:
Take the estrogens or birth control pills
Have conditions like having cancer or autoimmune disorders such as lupus
Obesity gain in mass
It is also more likely in the people whose blood is thicker than normal because too many blood cells are made by the bone marrow.
A genetic, or inherited may be source of excessive blood clotting
VTE is most common in adults who are 60 and older but they can occur at any age
VTE includes the deep vein thrombosis when a blood clot forms in a deep vein which is usually in the leg. And it includes pulmonary embolism when the clot breaks off and travels from the leg up to the lungs. DVT and PE are serious can be life-threatening conditions that require immediate medical attention.
DVT mainly affects the large veins in the lower leg and thigh which are always on one side of the body. The clot can block the blood flow and cause:
Changes in the skin color i.e. redness
Leg pain or tenderness especially in the calf
Leg swelling i.e. edema
Skin that feels warm when the touched
PE or pulmonary embolism can be fatal and occurs when the DVT breaks free from the vein wall and blocks some or all of the blood supply to the lungs thus leading to:
Unexplained shortness of the breath
Chest pain that may be worse upon taking deep breaths
Rapid heart rates
Even in some case passing out
