Deep Vein Thrombosis & Pulmonary Embolism
Also Known As:
Deep Vein Thrombosis – DVT, venous thrombosis, deep vein thrombophlebitis
Pulmonary Embolism – PE
Thrombosis is the process of blood clot formation. When the deep veins in the legs develop blood clots, it is known as deep vein thrombosis. The clot (thrombus) can either cause a partial block, which narrows the blood vessel, or a complete block, which cuts off the blood supply.
Technically, clots can occur in veins throughout the body, but they are most commonly noticed in the legs, thighs, and the pelvic area. DVT becomes a medical emergency when the clot breaks off and travels to other areas of the body, especially the lungs (causing a pulmonary embolism). It can also cause chronic venous insufficiency.
Note: Not everyone may experience all symptoms
- Smoking or the use of other tobacco products
- Standing or sitting for a long period of time
- Long journeys or bed rest for a long period of time such as after surgery.
- Weak blood vessels (AV Malformations)
- Blood-clotting disorders
- Birth control pills or hormone replacement therapy
- Heart failure
- Family history
- Cancer and/or chemotherapy
- Age – older adults are more affected
- Sex – more common in females
