Causes of congestion dermatitis

Congestion dermatitis is a relatively common skin disease, also known as stasis eczema or severe eczema. It often manifests as chronic flushing of the lower limbs, causing scaling, itching and swelling, and dark brown skin deposits. Such patients are prone to varicose veins and lower limb edema. Therefore, the harm is relatively large and must be treated promptly and effectively.

Causes of congestion dermatitis

The onset is related to varicose veins in the lower limbs. For people who stand for long periods of time, do heavy physical labor, or are pregnant with multiple pregnancies, pelvic varicose veins may be caused by congenital weak venous walls and venous valve defects, as well as venous occlusion following thrombophlebitis. Some believe that it is related to venous hypertension causing arteriovenous fistula or arteriovenous shunt in the affected area. Some people also believe that it is related to the increase in venous flow pressure, which causes local capillary dilation, widening of the gap between endothelial cells, and infiltration of fibrin into the interstitium. Fibrin forms a barrier around the capillaries, causing local skin tissue hypoxia and malnutrition. When varicose veins occur, venous return is blocked, blood flow slows down and flows backwards, causing venous congestion. The oxygen and nutrient content in the blood decreases, the capillary permeability increases, and fluid, protein, red blood cells, metabolic products, etc. penetrate into the tissues, forming edema. Slow blood flow induces infiltration of inflammatory cells. Chronic inflammation produces itching or abnormal sensation. The disease occurs due to stimulation such as scratching, friction or trauma.

treat

1. General treatment must first control venous hypertension. Seek treatment as soon as possible, elevate the affected limb when resting, and avoid standing for long periods of time or heavy physical labor. For mild varicose veins, they can be bandaged with an elastic bandage. For severe cases, surgery to tie off or other treatments may be required. Be careful to avoid scratching, as scratching may cause secondary infection. 2. Systemic therapy includes taking oral antihistamines to relieve itching and taking Chinese medicine to promote blood circulation and remove blood stasis. Local infections can be controlled with antibiotics, such as penicillin, cephalosporins, or quinolones.
