**10. Conclusion**

Chronic venous insufficiency (CVI) is a common disorder. As a result of various pathologies that develop at the lower extremity venous system, venous pressure increases, affecting the whole lower extremity. This could result in valvular insufficiency at superficial or axial deep veins and perforator veins, venous obstruction or a combination of these. These factors worsen with calf muscle pump dysfunction. These mechanisms partially provide grounds for the development of venous hypertension during standing. Patient may not have any symptoms, or they can complain from swelling at legs, discomfort with pain, anxiety, night cramps or pain occurring when standing. There are many treatment options such as medical, pharmacological and conservative methods used in CVI. Among these, conservative approaches because of being invasive with less adverse effects than other methods are commonly used to treat CVI. Conservative treatment of patients with CVI relies on the use of compression therapy, which is considered the "gold standard," provided by means of elastic stockings, bandages and pneumatic compression devices. Patient education is essential. CVI is a chronic disease that needs a life-long care. So patients with CVI should encourage to maintain a normal body weight, exercise daily (a walking program is especially good) and wear compression garment throughout the day.
