Small veins visible through the skin of your legs are called spider veins. Spider veins are early symptoms of venous disorder. Compression wear can help to relieve symptoms and prevent formation of further spider veins.
Any feeling of discomfort in the legs or visible cutaneous signs of dilated veins (called spider veins) can be early signs of venous disorder.
Basic medical knowledge on venous disorders
- With the term Chronic Venous Disorder (CVD) we describe a long-standing condition involving impaired venous return.
- If vein valves don’t close properly, a reflux results: the blood leaks downwards and stagnates in the vein, thereby leading to venous hypertension. This condition is known as chronic venous insufficiency (CVI) which may cause edema, skin change, and, in some cases, ulcerations.
- If left untreated, chronic venous insufficiency can result in the formation of serious disorders, including phlebitis and pulmonary embolism. To distinguish the different manifestations of CVD, the CEAP classification system is used.
- Acute venous disorders usually occur without pre-existing conditions, but they can also be triggered by chronic venous disorders. In any case, medical treatment is immediately required. Acute venous disorders include superficial thrombophlebitis, deep vein thrombosis (DVT), pulmonary embolism, post-thrombotic syndrome, and variceal bleeding.
