Glossary

Anticoagulants: Also known as “blood thinners”. They are medications that hinder the clotting of blood.

Artery: A blood vessel that carries oxygen-rich blood to the body.

Atrial fibrillation (AF): The most common type of irregular heart beat (arrhythmia). It is an irregular and often fast heartbeat that can lead to clot formation in the heart.

Blood clot: A collection of blood cells, platelets and fibrin (a protein) inside of a blood vessel, which obstructs the normal blood flow.

Body mass index (BMI): Is a measure of body fat based on height and weight. BMI is calculated by dividing your weight in kilos on your squared body height in meters (weight (kg)/height(m)2).

Computer tomography (CT scan):  Pictures of structures within the body created by a computer that takes data from many X-ray images and turns them in pictures. A CT scan can reveal details of internal organs that cannot be seen in conventional X-rays pictures.

Clotting: It is also known as “coagulation”. When a fluid, especially blood, changes to a solid or a semi-solid state. Clotting is a natural process inside the body to prevent excessive bleeding when there is injury to a blood vessel (i.e. when you cut yourself)  but can be problematic if it is excessive.

Clotting factors: A group of proteins in the blood that act together to produce a fibrin clot.

D-Dimer: A marker of the breakdown of a clot. It is routinely checked in blood tests to during the diagnosis of a DVT or PE.

Deep vein thrombosis (DVT): A condition that occurs when a blood clot forms in a deep vein, usually in the leg or thigh.

Distal DVT: A DVT below the knee

Embolus: A blood clot that forms in a blood vessel in one part of the body and breaks away and travels to another part of the body.

Fibrin: A protein that binds cells (platelets, red cells, etc.) together in a blood clot.

Idiopathic: Any disease that is of uncertain or unknown origin may be termed idiopathic

Platelet: A small disc-like fragment in blood that help in blood clotting by attaching to other platelets and to damaged blood vessel lining.

Post-thrombotic syndrome (PTS): Is a long-term complication of DVT caused by damage to the walls and the valves of the vein. It causes pain, swelling and occasional ulceration of the leg.

Prophylactic therapy: A treatment measure used for the prevention of a disease.

Provoked VTE: A DVT or PE that occurs in the presence of an identifiable risk factor (hospitalization, major surgery, pregnancy, trauma, etc.)

Proximal DVT: A DVT above the knee

Pulmonary embolism (PE): The blockage of small arteries in the lungs from a clot that has traveled there (embolized) from elsewhere in the body.

Risk factor: A characteristic or exposure of a person that increases the chance of developing a disease. Risk factors may be temporary like surgery, pregnancy and long-distance travel. Risk factors may also be permanent like inherited conditions and cancer.

Stasis: The slowing of flow of a fluid in the body (i.e. blood flow in the veins and arteries).

Thrombophilia: Inherited or acquired abnormalities of the blood that increase the risk of abnormal blood clotting.

Thrombectomy: Surgical removal of a thrombus from a blood vessel.

Thrombus: Also known as a blood clot. It is a collection blood cells and fibrin inside of a blood vessel.

Ultrasound Scan: A painless test that uses sound waves to create images of organs and structures inside your body.

Unprovoked VTE: A VTE that occurs in the absence of any obvious risk factors.

Veins: The vessels that carry blood that is low in oxygen from various parts of the body back to the heart.

Venous Thromboembolism (VTE): Deep vein thrombosis (DVT) and pulmonary embolism (PE) are collectively known as VTE.
