Venous thromboembolism is a disease that occurs mainly in the legs and lungs and is at risk of death. If the legs are red, swollen or feverish, be sure to seek medical advice promptly.
Venous thrombosis has high incidence and disability rate
Thrombosis refers to the formation of blood clots in arteries or veins, and is the root cause of three largely fatal cardiovascular diseases (heart disease, stroke and venous thromboembolism). Venous thromboembolism, a condition in which blood clots in the legs and lungs are not considered as important as heart attacks and strokes.(This means not being taken seriously.)
Data provided by the international society for thrombosis and hemostasis show that one person develops venous thromboembolic disease every 16 seconds and one person dies of the disease every 37 seconds. Deep venous thrombosis and pulmonary embolism are the most common causes of hospital death with high morbidity and disability.
But what’s even more scary is that many times a venous thrombosis occurs without obvious symptoms. Once the thrombus falls off, the emboli can arrive with the blood stream to the pulmonary obstruction vessels, the occurrence of very dangerous pulmonary embolism.
Clinicians have little time to rescue patients, and severe cases can die within 1 to 2 hours, and the risk of recurrence of fatal pulmonary embolism still exists in patients who pass the critical period.
Hospitalization, surgery and sedentary are high risk factors.
Hospitalization, surgery and sedentary can all increase the incidence of venous thrombosis; and with the improvement of living standards, dietary habits and lifestyle changes in recent years, the number of young people suffering from venous thrombosis is increasing.
Many young people do not pay attention to diet, high fat, high cholesterol, do not like to eat vegetables love to eat meat, drink less water, resulting in blood viscosity, leading to increased incidence of venous thrombosis.
In addition, the data showed that for every hour of sitting still, the risk of developing DVT increased by 10%, and sitting for more than 90 minutes reduced blood circulation of the knee joints by 50%. That means the sedentary office population is at risk, too.
Swelling of the lower limbs requires immediate medical attention.
The most obvious symptoms of venous thrombosis are swelling of the lower limbs, pain, and elevated skin temperature, so once these symptoms are found, it is best to see a doctor immediately, and vascular ultrasound can be used to help diagnose them.
Venous thrombosis is different from muscle pain.
After walking for a long time, the pain is mainly fatigue of the muscles, which will improve after the rest. It is completely different from the swelling of venous thrombosis. The characteristic of venous thrombosis is swelling first, then swelling pain again. This kind of pain is not very severe, and it is tolerable. Mainly swelling.
If the leg is swollen for a long time and can’t be relieved after resting, it’s time to be on the lookout for venous thrombosis. “it is best to seek medical advice as soon as the swelling is detected, and early intervention will be much more effective. ”
In addition, we should also pay attention to distinguish with arterial thrombosis.
Arterial thrombosis to the lower limb of severe pain, not swelling or swelling is not obvious, arterial thrombosis is also very dangerous, so it is recommended that no matter swelling or pain, as long as the lower limb symptoms will be the first time to go to the hospital.
Anticoagulant therapy, once initiated, lasts a lifetime.
However, venous thromboembolism disease is preventable and treatable, early detection and active treatment to prevent the occurrence of pulmonary embolism, can significantly reduce the mortality rate.
Active participation in exercise will effectively reduce the risk of blood clots. If you spend a lot of time in a stationary state, such as driving or taking a long flight, or even sitting at your desk, especially with your knees bent, it is recommended to take a moment to stand up, stretch your legs, and walk around. This is very important for healthy blood circulation.
For patients who need to stay in bed because of illness, it is also necessary to take the initiative to move lower limbs, which can effectively reduce the incidence of pulmonary embolism in hospital.
As for treatment, the current domestic and international clinical guidelines have pointed out that anticoagulation is the cornerstone of the prevention and treatment of venous thromboembolic disease. Need to remind that anticoagulant therapy once started to continue for life, patients can not stop drugs at will.
