A friend told Hanako that she had always had leg pain in recent days, but she had not been traumatized, and suspected that she had a deep veined blood clot. Hanako asks her why she thinks this way, and her friend says that she has inquired about the information on the Internet, "Blood clots come to the leg prophet", and leg pain is a precursor to blood clots. She also saw someone die of a pulmonary embolism caused by a deep vein thrombosis, which scared her a lot.
Huazi told her friends not to scare themselves, deep vein thrombosis can not be diagnosed by themselves, and going to the hospital for examination in time is the most correct choice.
1. Venous thrombosis is not the same as arterial thrombosis
When it comes to blood clots, everyone will think of cerebral infarction, myocardial infarction and other diseases, in fact, these are thrombotic diseases that occur in the arterial system. In addition to arteries, blood clots may also occur in veins.
If blood return is restricted and stasis in the veins, venous thrombosis may form under the action of coagulation factors, often involving the deep vein trunk. However, venous thrombosis is different from arterial thrombosis, and generally does not cause insufficient blood supply to important organs, so the initial symptoms are not obvious, and the impact on physical health is also small.
However, once the venous thrombus falls off, it will run with the blood flow, blocking the pulmonary artery with a small caliber, causing pulmonary embolism and life-threatening.
2. Leg symptoms when venous thrombosis occurs
The lower extremities are far from the heart, and because of gravity, blood is prone to stasis in the lower extremities, so deep vein thrombosis of the lower extremities is more common. Anatomically, the left iliac common vein is susceptible to cross compression of the right common iliac artery, so the left leg is more susceptible to venous thrombosis than the right leg.
Lower limb trauma, fractures, long-term bed rest, long-term transportation and other reasons, will cause the lower limbs to brake for a long time, which is the main factor inducing deep vein thrombosis. Factors such as smoking, kidney disease, obesity, advanced age, and oral contraceptives may also induce deep vein thrombosis.
People with associated risk factors need to be alert to venous thrombosis if they have abnormalities in the legs.
1. Swelling: If there is a venous thrombosis, the blood return is blocked, it will accumulate in the legs, causing swelling of the legs. Water in the blood also oozes out of the blood vessels and accumulates in peripheral tissues, causing edema. The leg where the thrombus occurs will be thicker than the other leg.
2. Pain: the pain caused by venous thrombosis is mostly inconspicuous chronic dull pain, or when the calf is squeezed and pressed, it will appear locally. And there may be an inflammatory reaction in the painful area, causing local fever, which feels a little hotter than other parts.
3. Discoloration: if the leg swelling is more severe, the skin will be tight, white and shiny; if there is an inflammatory reaction, it may appear red; if there is exudation and bleeding under the skin, the skin may appear bluish-purple. It may also be accompanied by symptoms of skin scaling and itching.
Third, how to prevent deep vein thrombosis
Long-term immobilization of the lower limbs is the main risk factor for inducing venous thrombosis, so the key to preventing venous thrombosis is "movement". Increase the amount of exercise and do not stay in the same position for a long time. If you take a long time in transportation, you can hook your toes 20 times every 1 hour, which can prevent venous thrombosis.
If lower extremity surgery, fractures, inability to move, or advanced age, high coagulation, anticoagulant drugs can be used for prevention under the guidance of a doctor. If a blood clot has formed, do not massage and vigorously rub to avoid causing the thrombus to fall off. A strainer can be placed in the vein to block the shedding blood clot leading to pulmonary embolism.
If symptoms such as cough, dyspnea, chest pain, etc. suddenly appear, you should be alert to the occurrence of pulmonary embolism and need to seek immediate medical attention for thrombolytic therapy.
To sum up, the leg pain caused by venous thrombosis is mainly distended and painful, and may be accompanied by discoloration, itching and other conditions. If there is a long-term immobilization of the lower limbs and symptoms in the legs, it is necessary to go to the hospital in time to check, find the problem and actively treat, and use drugs to prevent the occurrence of pulmonary embolism under the guidance of doctors.
