Skin discolorations - where do they occur most often?
Skin discoloration arises as a result of leakage of red blood cells from leaky capillaries. A typical place of occurrence of discolorations is the frontal and medial region of the later part of the shin in the area of varicose veins. There may also be atrophic dermatitis in this area. Symptom is the appearance of the skin - dry, thinned, flaky and very itchy.
Development of the disease - skin changes
As the disease develops, local skin sclerosis appears. It fibrates the skin and subcutaneous tissue. It becomes tense in places painful and sensitive to touch. You may get ecchymosis. Strained and shiny, it overlaps with red-brown coalescing patches. At this stage even slight damage to the skin can lead to a difficult to heal ulcer.
Ulcers - where they occur most often?
Ulcers associated with post-thrombotic syndrome usually occur on the shin, over the ankles (as well as on the shins). The skin covering the shin is particularly vulnerable to pathological changes. This is a poor blood supply (especially for people with circulatory insufficiency, atherosclerosis or diabetes); lies close to the tibia and is sensitive to injuries. Localized near varicose veins and accompanying venous stasis leads to a large accumulation of inflammatory and metabolic waste - carbon dioxide, urea, etc. in this place. The result is hypoxia, intoxication and atrophic changes in the skin.
Dangerous ulcers
In this condition, even a small wound can be kept open and filtered with sticky secretion instead of healing. Sometimes the post-thrombotic team gets involved in the spread of ulcers that can cover the entire perineum of the shin and dig deep into the fascia covering the muscles. Treatment of such changes often lasts for years.
Leg ulcers
Heavily healing ulcers - a complication of deep vein thrombosis (chronic venous insufficiency) - also occur on the lower leg. They usually occur in the elderly, but they also happen in younger patients. (Every fifth person complaining of this disease is not yet 40 years old.). In 75% of cases, ulcers are caused by chronic venous insufficiency, in 8% - arterial diseases, 3% - diabetes, and 2% - injuries. In 14% of cases, the origin of ulcers is of a different nature.
RECOGNITION OF THE POSTURE BAND
The difficulty of symptomatic (clinical) diagnosis
It should be remembered that the above described symptoms of post-thrombotic syndrome are not characteristic (specific). Their causes can also be quite different - for example, poor circulation in smaller veins, advanced age, obesity or leg injury.
Picture diagnosis
Imaging studies will help determine whether it is a post-thrombotic syndrome after a thrombosis not diagnosed before or a recent thrombosis. Research includes diagnostic imaging using ultrasound, enriched with the ability to measure the direction and speed of blood flow. For this purpose, the Doppler effect is used, and the measuring device is called the Doppler flowmeter. In the simplest version, the flow meter only informs about the presence or absence of flow on a given section of the vessel.More expensive, more advanced devices show a number of blood flow parameters, vessel image in 2 and even 3 dimensions, and in the most extensive version the blood in the vessel is computerized "colored" depending on the direction and speed of the flow (the so-called color doppler).
