Deep vein thrombosis (DVT) occurs when a clot forms in the deep veins, usually of the leg. You may notice pain or swelling in the calves, or there may be no symptoms whatsoever. Though these may seem mild, DVT is a serious medical condition for which specialists recommend immediate care. The more you know about this condition, the better you are able to protect yourself from them and handle them correctly if they appear.
Thrombus (as in “thrombosis”) is the medical term for a blood clot. Injuries cause the clotting function to activate to stop excessive bleeding. Occasionally, that clotting activates in the blood vessels, and the platelets and other items which make up blood become a mass that may impede blood circulation.
This is a major complication of DVT. The clot that forms is not permanently set up. It may shake loose, travel through the bloodstream, and block a blood vessel in the lungs. Indications of a pulmonary embolism include chest pain, difficulty breathing, dizziness, a rapid heartbeat, and coughing up blood.
When both DVT and a pulmonary embolism occur, together they produce this disorder. Literally, it’s the blood clot (a deep vein thrombus especially ) breaking loose, traveling around, and winding up in the lungs.
Developing DVT can cause postphlebitic syndrome, if the blood vessels around the clot are ruined. Blood can’t flow easily, causing pain or swelling of the legs and discoloration or sores on the skin. It could take years for symptoms to be observable.
Phlegmasia cerulea dolens:
This is a really extreme but uncommon kind of DVT. Clotting occurs repeatedly, which leads to the area affected to become quite painful, swollen, and turn white or blue. The odds of developing a pulmonary embolism are markedly improved, and the blood circulation might be cut to the extent that gangrene can set in.
D-Dimer is a chemical the body releases when blood clots dissolve. Therefore, it is also a blood test used to check for clots in the veins. A positive result does not necessarily signify DVT, as other factors can lead to D-Dimer manufacturing, like falling or pregnancy. In other words, the d-dimer test must be used carefully and with additional tests are frequently used in combination.
People with clotting disorders and others in a higher risk for developing a clot are often put in an anticoagulant, or blood thinner. It helps discourage cells from clotting as readily.
The three facets of Virchow’s Triad clarify how DVT forms. Venous stasis, hypercoagulability, and damage to the endothelial lining of the veins all play a role in the clot’s formation, and helps the medical community understand contributing factors to DVT.
This first element of Virchow’s triad refers to an alteration in blood flow–especially, it slows down. A sedentary lifestyle or sitting for quite a long time, like during a car trip or during the recovery phase of an illness, result in the development of DVT. It’s particularly important to move the legs as much as possible during these times.
Hypercoagulability signifies an increased risk for developing a clot. It may be blood disease, cancer, age, or pregnancy, among other items which produce the blood clot more easily. Just because a man is in a hypercoagulative condition doesn’t mean they’ll absolutely develop a clot, but it is essential to be vigilant.
