From the appearance, most of them are twisted and twisted like earthworms, and sometimes the skin of calves is atrophied, desquamated and pigmented.
Although painless, it not only affects the appearance, but also brings potential harm to the body.
Four hazards of varicose veins
1, venous thrombosis
Some patients can form thrombus in varicose superficial vein, which shows local redness and pain, hard mass formation, and pain affects walking. If not treated in time, thrombus may spread upward or spread to deep vein through communicating vein, causing deep vein thrombosis.
2, skin pigmentation
Long-term venous hypertension leads to the increase of capillary permeability in the lower leg. After exudation, red blood cells rupture and iron-containing proteins are deposited under the skin, which makes the skin black and develop from punctate to flaky.
3. Ulcer
Varicose veins cause skin nutrition changes and lead to ulcers, which can last for a long time, causing local stench and pus, which has a serious impact on daily life.
4, bleeding
The skin in the area where varicose veins pass is very fragile because of insufficient nutrition. If you are not careful, it is easy to cause varicose veins to rupture and cause massive bleeding.
