Double lower extremity venous thrombosis symptoms?

summary

Lower extremity venous thrombosis is a serious disease, but because most people do not know much about the disease, especially for the specific symptoms of lower extremity venous thrombosis is not very clear, the symptoms of this disease with a guess psychology, the general people will always have the idea, often think about it too much, whether fatal and so on. Now we mainly introduce the main symptoms of lower extremity venous thrombosis

Double lower extremity venous thrombosis symptoms?

Swelling of the affected limb is the most common symptom after venous thrombosis of the lower limb. The tissue tension of the affected limb is high, showing non depressed edema. The skin color is reddish and the skin temperature is higher than that of the healthy side. When the swelling is serious, blisters may appear on the skin. The swelling sites were different with the different thrombus sites. In patients with iliofemoral vein thrombosis, the whole affected limb swelled obviously; In patients with venous thrombosis of the calf, the swelling was limited to the calf; In patients with inferior vena cava thrombosis, swelling of both legs occurred. If the thrombus starts from iliofemoral vein, the thigh swelling will appear in the early stage. If it starts from the calf venous plexus and gradually extends to the iliofemoral vein, the calf swelling first occurs, and then the thigh is involved. Most of the swelling was the heaviest on the 2nd and 3rd day after onset, and then gradually subsided. When the thrombus subsided, the tissue tension was weakened first, and then the peripheral diameter of the affected limb was gradually reduced, but it was difficult to turn to normal, unless the thrombus was completely removed in the early stage. In the late stage of thrombosis, although part of the veins have been recanalized, the venous pressure of the affected limb is still high due to the destruction of the venous valve function, which is similar to the primary lower limb valve insufficiency.

There are two main causes of pain and tenderness: 1. Thrombus causes inflammatory reaction in the vein, causing persistent pain in the affected limb. ② The thrombus blocked the vein, blocked the venous return of the lower extremity, distended the affected limb and aggravated the pain when standing. Tenderness is mainly confined to the site of inflammatory reaction caused by venous thrombosis, such as femoral vein or leg. The tenderness of calf gastrocnemius is also called positive Homans sign. Due to the risk of thrombus falling off by squeezing the leg, the force should not be too large.

Superficial varicose vein is a compensatory reaction. When the main vein is blocked, the venous blood of the lower extremity flows back through the superficial vein and the superficial vein expands compensably. Therefore, the superficial varicose vein is not obvious in the acute stage, which is a manifestation of the sequelae of lower extremity venous thrombosis.

matters needing attention

Eat fresh hawthorn or use Hawthorn bubble boiling water, add the right amount of honey, cool when tea. It can dilate blood vessels, reduce blood pressure and promote cholesterol excretion. When patients need to stay in bed for a long time after disease or trauma or surgery, they should pay attention to the position of feet high and head low, which is conducive to the return of lower limb blood.
