Lower extremity venous vascular sclerosis, mainly increased pressure of trunk veins and capillaries, causing skin microcirculation obstruction, and in severe cases, skin ulcers can be formed. Increased pressure of trunk veins causes superficial vein expansion and increased pressure of capillaries causes skin microcirculation disorder. It causes capillary enlargement and pericapillary inflammation and increased permeability. Serum protein leakage and pericapillary fibrous tissue deposition. Causes reabsorption disorders and lymph node overload, leading to lower limb edema. Non-surgical treatments such as compression stockings are generally used, as well as sclerotherapy with sclerosing agent injection and compression therapy, and surgical stripping if necessary. If lower extremity venous vascular sclerosis occurs, you need to seek medical treatment as soon as possible, and do not use drugs on your own to avoid serious complications.
