Varicose veins are twisted, dilated veins most commonly located on the lower extremities. Varicose veins are subcutaneous veins dilated to at least 3 mm in diameter when measured with the patient in an upright position. They are part of a continuum of chronic venous disorders ranging from fine telangiectasias, also called spider veins, (less than 1 mm in diameter) that present in 43% of men and 55% of women and reticular veins (1 to 3 mm in diameter) to chronic venous insufficiency, which may include edema, hyperpigmentation, and venous ulcers. Chronic venous disease is most commonly described using the CEAP (clinical, etiologic, anatomic, pathophysiologic) classification system. Varicose veins are present in 30% to 60% of adults and increase in incidence with age. Endovenous ablation techniques are minimally invasive procedures used in the treatment of varicose veins. These techniques involve the application of thermal or chemical energy to close off and seal the affected veins. This technique has gained popularity in recent years as a highly effective and less invasive alternative to traditional surgical methods for managing varicose veins. Endovenous ablation involves the use of thermal or chemical energy to close off and seal the affected veins from within, thereby redirecting blood flow to healthier veins. By targeting the diseased veins directly, these techniques minimize the need for surgical incisions and promote faster recovery with fewer complications. It's important to note that the choice of endovenous ablation technique depends on various factors, including the patient's individual characteristics, the location and size of the varicose veins, and the expertise of the treating physician. The selection of the most appropriate technique is typically based on a combination of clinical assessment, patient preference, and physician experience.
