Varicose veins can be primary or secondary. While various theories exist regarding the causes of primary varicose veins, the exact causes remain unclear. The most widely accepted theory today is a hereditary weakness in the venous wall and venous valve insufficiency, leading to venous hypertension.
Secondary or acquired varicose veins result from damage to venous valves caused by trauma, deep vein thrombosis, or inflammation. Along with prominent, tortuous varicose formations in an extremity, smaller telangiectatic and reticular formations may also be present. These formations appear as superficial, less than 1 millimeter in diameter, blue or red linear discolorations in the skin, and are not palpable.
Regionally, these formations can be star-shaped or resemble spiderwebs, presenting as widespread linear formations that can encompass the entire leg. The distribution of these formations can vary from patient to patient, appearing together or separately on an extremity.
Varicose veins are generally classified into two types.
Varicose veins developing due to insufficiency of the superficial leg veins cause these superficial veins to thicken, forming thick, tortuous, and bulging veins beneath and through the skin. This type of varicose vein can eventually damage the deep venous system, necessitating intervention after a certain point. They can pose a risk to leg health.
Telangiectasia or spider veins, often appearing as increased numbers of fine superficial varicose veins, are more commonly caused by hormonal influences, as well as genetic and structural factors. These are primarily a cosmetic concern; that is, their appearance is bothersome. They do not pose a serious threat to leg health or overall health.
