How does leg vein thrombosis form to do?

summary

Venous thrombosis of the lower extremity is a common peripheral vascular disease. Venous valve insufficiency and pulmonary embolism caused by venous thrombosis of the lower extremity is a great danger to the labor force and life safety of patients. The disease has been paid much attention in clinic. Weierxiao, a famous medical scientist in the 19th century, proposed that the three major factors of venous thrombosis are blood stagnation, venous wall damage and hypercoagulability. How does leg vein thrombosis form to do? Next, I'd like to share my views with you.

How does leg vein thrombosis form to do?

Mechanical methods are designed to promote venous return in the lower extremities. The stimulation of gastrocnemius muscle with electrical stimulator can effectively promote limb circulation by using circulatory driver or rhythmic positive pressure or negative pressure driver. It is also important to encourage patients to do ankle and quadriceps activities as soon as possible, do more deep breathing and coughing, and get out of bed as soon as possible. The patients who wear medical elastic socks with pressure difference after operation, such as 4.0kpa (30mmhg) in the lower leg and 2.67kpa (20mmhg) in the thigh, also play the role of circulation driving.

The first drug prevention method is low-dose subcutaneous heparin therapy. According to the comprehensive data, the incidence rate of deep venous thrombosis after operation is reduced from 25% to 7%. The incidence rate of large pulmonary embolism dropped from 6% to 0.6%. The mechanism of the preventive effect of low-dose heparin is not fully understood. The main reason may be that the absorption of drugs is slowed down by subcutaneous route and the body keeps a certain heparin concentration continuously.

The general method of use is to inject 50mg subcutaneously 2 hours before operation, and then every 12 hours, 50mg each time. Antiplatelet therapy mainly includes enteric coated aspirin and dipyridamole. The effect of low molecular dextran is to reduce the blood viscosity. 500-1000ml dextran can be given intravenously every day.

matters needing attention

Eat more high-quality protein, such as milk, chicken and duck (preferably wild Chaiji), fish, eggs (yolk should be less), bean products, less pigs, cattle, mutton, and lean meat is better. Eat foods rich in vitamin C, such as fresh fruits, tomatoes, hawthorn, etc;
