In addition to arteries and veins, the body has lymphatic vessels through which a special fluid - lymph - moves. Its main function is to participate in metabolism and detoxification of the body, it also contains special blood cells - lymphocytes, which protect the body from infections.
In congenital anomalies of lymphatic vessels, the flow of lymph from tissues to large veins is disturbed, which leads to fluid accumulation and stagnation -
lymphostasis. It can also occur after surgical intervention - for example, for breast cancer, if the lymph nodes were removed.
Other causes of lymphedema are:- Trauma;
- burns;
- radiation;
- Chronic infections (e.g., rheumatoid inflammation).
