Deep vein thrombosis - blood clot leg

What is Deep Vein Thrombosis Is deep vein thrombosis?

Arteries are blood vessels that is transmitted through blood from the heart to various parts of the body. And veins are blood vessels that return blood from which the various parts of the body to the heart. And contains a wall of the arteries to help thin muscles in pumping blood from the heart to various parts of the body. In contrast, the veins that do not contain muscles in the wall, and return blood to the heart through the veins as a result of the era of the muscles of the veins during the movement of the body. And thus movement of the body is working to help return the blood to the heart.
And there are two types of leg veins: superficial veins and deep veins.
Superficial veins Superficial Veins: located just under the skin and can be easily seen on the surface of the skin.
 Deep vein Deep Veins: Located deep within the muscles of the leg.And moves blood from the superficial veins to deep veins through small veins connecting the other two are called perforating veins Perforator veins.

 Contains superficial veins and perforating veins on the valves one direction to allow the movement of blood towards the heart only, and not back in the opposite direction of the heart
 Direction normal to the vein blood flow (in the direction of the heart only and not vice versa) contains superficial veins and perforating veins on the valves, one-way to allow the movement of blood toward the heart only Stroke occurs as a result of stasis leg veins for any reason. They are not a blood clot in the deep veins dangerous per se. But the danger lies in the case of fragmentation of part of the clot and moving with the blood stream until it reaches the lungs and leads to blockage of the pulmonary artery Pulmonary embolism and this so-called pulmonary shells.
 Causes of deep vein thrombosis 
Usually, the blood in the case of steady flow, and when there is no reason leads to stagnation of blood there is a danger of blood clots from forming.

Causes of deep vein thrombosis Usually, the blood in the case of steady flow, and when there is no reason leads to stagnation of blood there is a danger of blood clots from forming.
And summarized the reasons that help in the formation of blood clots following:

     Rest in bed for long periods, and travel on long trips: walking lead to a contraction of leg muscles and push the blood in the veins of the leg to return to the heart. In the case of rest and not moving for long periods occur stagnation of blood in the veins of the lower leg
.
Surgery: the lead to increase the level of blood clotting factors.

     Long stay in hospital.

     Pregnancy, and post-natal period (6-8 weeks after birth).

     Of obesity.

     Some medications such as oral contraceptives.

     Smoking.

     Cancerous tumors.

     Broken leg.

     Genetic factors.

  1.   Deep vein thrombosis

    Superficial vein thrombosis:

         Redness, heat, pain, and swelling at the place of the injured vein and surrounding skin.

         When you touch the vein is injured by a sense of like a thick rope.

    Deep vein thrombosis:

         Redness, pain, swelling, and hot leg.
Pulmonary artery Pulmonary embolism: sometimes disintegrate part of the clot and move with the tide of blood (pulmonary shells) until you reach the lungs and cause pulmonary artery. And the patient complains of severe chest pain, difficulty breathing, fainting, and threatening the life of the patient.
Diagnosis of deep vein thrombosis Diagnosis:

Superficial vein thrombosis:
Diagnosis is made through a medical examination.

Deep vein thrombosis:
Diagnosis is made by:

     Ultrasound Ultrasound: be sure of a stroke, and locate the leg, and size. And veins are seen above the knee and compare the veins below the knee.

     X-ray venography Venography: dye is injected into a vein and then is the work of the rays to look for a vein clot in it.

Magnetic resonance imaging MRI: appears at the top of the leg veins and pelvic area.

De dimer D-dimer: a blood test can be used to detect the presence of stroke, showing a chemical when the clot dissolves gradually.


 Superficial vein thrombosis:

     Put warm compresses place of leg pain.

     Anti-inflammatory drugs such as ibuprofen.

Deep vein thrombosis:

     Is to determine the cause of stroke treatment.

 If the clots in the veins below the knee (in the calf): The follow-up ultrasound several times to make sure non-proliferation of blood clot in the veins above the knee to avoid pulmonary shells.

     If the clots in the veins above the knee is used anticoagulants.

And anticoagulants to prevent blood clots from forming and prevent clots from forming as well as small to reach the lungs.

And anticoagulants are given in two steps. The first step is a drug warfarin Warfarin in the form of tablets. And is used for a period of 3-6 months. And needs to be a week or more to start showing its effect and impact. Therefore, the patient is given at the same time (second step) where the drug heparin Heparin effect begins rapidly. And injectables is taken intravenously, and is the work of several blood tests to determine the dose needed by the patient.

And recently there is a low molecular weight heparin and low molecular weight heparin is administered injectables under the skin once or twice a day without the need for blood tests to determine the dose.

Prevention of deep vein thrombosis:


     Recommended to use compression stockings medical patient who had suffered a leg injury before
