2.2. Varicose Veins of THE LOWER EXTREMITIES

Varicose VEINS OF THE lower extremities refer to a vascular disease characterized by elongation and serpiginous tortuosity of the subcutaneous veins, along with saccular dilatation of their lumen. This is a very common vascular pathology affecting 17-25% of the population, with women being affected 3 times more often than men (M.I. Kuzin).

The Prerequisites for the development of lower extremity varicose veins include congenital or acquired venous wall alterations; the presence of non-functioning arteriovenous anastomoses; and neuroendocrine disorders that lead to a decrease in the tone of venous walls. The condition is triggered by factors that cause increased venous pressure in the lower extremities and impaired venous Blood outflow (occupations requiring prolonged standing—such as shop assistants, surgeons, and loaders—as well as chronic constipation, coughing, and Pregnancy).
