Vein stones are solid formations in blood vessels, formed from protein and inorganic compounds of calcium, magnesium, uric acid, etc. Stones develop in most cases of long-term chronic diseases such as varicose veins (varicose ulcers, thrombophlebitis), congenital disorders of the venous circulation , cancer, and also after a long period of inactivity (as a result of immobilization of body parts). Sometimes they can form as a complication after angiography (percutaneous probing of the arteries).
Concretions are very diverse in shape, size, composition and location
