As is known, blood has the ability to fold. This is a normal protective mechanism that stops the bleeding vessel is damaged.
But endothelial inflammation (intima) also perceived as damage to the body, andblood when it starts to curl up inside the inflamed vessel. Typically, this process develops in the veins, since the velocity of blood flow in them smaller and thinner wall than the arteries. In this form blood clots — clots that narrow the lumen of the vessel and prevent the normal outflow of venous blood. This condition is called thrombophlebitis.
Most thrombophlebitis develops in the calf, as the flow velocity therein is minimal, and the load on the vascular wall and a large venous valves.
Sinceclot continuously grows, its top (attachment) can be in the calf, and the end (loosely located in the lumen) — the lower vena cava,
For the prevention of pulmonary embolism thrombophlebitis prescribe special drugs that reduce blood clotting, and used surgical techniques for removal of blood clots.
There are ways to stop detached clots in the inferior vena cava. One — stitching the vein. In the lumen of the vein forms multiple channels. The blood on them to flow freely, and blood clots are delayed.
Torn and blood clots can be captured using a special filter installed in the inferior vena cava. Invented many varieties of such filters. For example, some have an umbrella shape. When folded, this "umbrella" is held in the vein and there is disclosed. "Rods"
An improved model of the filter resembles an hourglass. Such a filter is stronger, it is attached to the inner vein wall, forming a double barrier. In recent years, widely used, setting the time, the removable filter. When the risk of complications is reduced, filter can be removed.
Suspect thrombophlebitis deep leg vein is possible, if:
- do you have pain in the calf muscles, worse when moving, especially in flexion of the foot;
- redness or swelling of the legs, fever in edema.
In this case it is best to go for a consultation with
