Generally, the injury of vascular wall, blood stasis, blood composition change people prone to deep venous thrombosis of lower extremity. Specifically the following.
1 long term bedridden patients. Due to long-term bed caused by blood stasis, prone to deep venous thrombosis of lower extremity.
2 a person who travels by plane or by train. The higher incidence of deep venous thrombosis of lower extremity, also because of long waist brake, venous return is obviously slowed down, prone.
3 elderly. The blood coagulation factor activity is higher in the elderly, and the role of leg muscles to promote blood circulation is weakened, so it is easy to suffer from the disease.
4 patients with malignant tumor. Malignant tumor can release procoagulant substances, leading to high blood coagulation state.
5 women taking oral contraceptives. It has been demonstrated that the estrogen pill can cause changes in blood clotting factors, predispose to thrombosis.
6 postpartum women. Because of the change of estrogen, it is easy to cause thrombosis.
7 patients after surgery and trauma. Because of the damage of the blood vessels and thrombosis.
8 autoimmune diseases. Such as systemic lupus erythematosus.
9 patients with primary blood hypercoagulability due to genetic defects.
In addition, race, blood type and so on have a certain impact on the disease, such as the incidence of Asians than Asians high, type A blood of the people with a higher incidence of the disease.
The sedentary, long lying, standing for a long time why easily lead to venous thrombosis?
The three major causes of venous thrombosis is blood stasis, vascular endothelial injury and blood composition change, those factors can cause these three changes are prone to cause venous thrombosis. A long time to maintain a posture unchanged, sedentary, long lying standing for a long time will cause the venous return slows down, leading to venous blood stasis, which led to the formation of venous thrombosis. It can not be a long time to maintain a posture unchanged, if the nature of the work had to be sedentary or stand, to be good at self adjustment, over a period of time to change the posture, such as sedentary office work, after a period of time can stand up and move around, can prevent the formation of venous thrombosis.
