How Deep Vein Thrombosis Occurs

Deep Vein Thrombosis
Deep vein thrombosis is a problem that is caused by pooling of blood in the vein, which triggers blood-clotting mechanisms. Anyone who sits for long periods of time in a vehicle, movie theater, or even an office desk may develop clumps of clotted blood in the legs. Deep vein thrombosis (DVT) is the formation of a blood clot, known as a thrombus, in the deep leg vein.
DVT commonly causes pain, swelling, or redness in the affected leg. Most people brush it off as temporary fatigue and pain. And, while DVT itself can cause pain and swelling, it’s a precursor to Pulmonary Embolism, a potentially fatal condition where a DVT blood clot moves to a critical artery of the lungs.
Some doctors believe that DVT is “more common today as a result of two factors, the increase in the number of frequent flyers and airline deregulation”. As a result of deregulation, the distance between one airline seat to the one in front of it is no longer regulated. Many airlines moved seats closer together in order to fit more passengers on the planes thereby reducing the leg room between seats from 40 inches to 28.
The first is cabin pressure – please do not try to do anything to change this in order for you to reduce your risk to DVT. Doing so may cause you to explode or be sucked out of the cabin so fast you will become numb from the sheer velocity.
Another type of surgical procedure associated with the removal of varicose veins involves a PIN stripper being introduced into the vein. The end of the stripper is actually sewn to the vein and when the PIN stripper is removed, so is the vein. You may be able to have this procedure done in an outpatient center, although some doctors still use the operating room to perform this type of surgery.
The Acting Surgeon General spoke to the leadership of the American Venous Forum about raising national awareness of the risks of Deep Vein Thrombosis and Pulmonary Embolism just moments after issuing a “Call to Action” on the condition.
Fortunately, the blood does clot up normally, doing its job after surgery, but the downside is when blood clots occur in the wrong place, such as the thigh or calf, it’s not like you can take a bunch of blood thinning agents while your surgery wound is trying to seal up. Being dormant poses risk for clotting as well.
Blood travels quickly through arteries, which actively pump the blood to all parts of the body. Veins, on the other hand, are passive and blood flow relies on a one-way valve system. Whenever the muscles are flexed or arms or legs moved, it causes the muscles to squeeze the veins, causing blood to flow back to the heart. If there is prolonged immobility, then the blood can clot.
One thing is certain; we are now exposed to an environment which our forefathers were not. The air that we breathe, the earth where we grow our vegetables and fruits and our water resources are now polluted with chemicals.
