Varicose veins are widened, elongated, tortous vein located in subcutis, their size being 3mm in diameter or more. Pathogenesis of varicose veins is complex. In the research beginnings, largest importance was attributed to incompetent venous valves. In further research, mollecular mechanisms of venous wall damage were discovered, which contribute to development of venous hypertension and venous reflux. Varicose veins are common problem in adult population, almost 30% of people are affected. The disease can be asymptomatic and symptomatic. Encountered symptoms are pain, leg heaviness, edema, itching, night cramps, restless legs and cosmetic defect. Advancement of chronic venous disease leads to chronic venous insufficiency and development of severe forms of the disease, C3-6 in CEAP classification, such as edema, lipodermatosclerosis or ulcers. Thorough physical exam and DUS as golden standard in assessment of venous morphology and location of venous reflux are essential in appointing the correct diagnosis. Treatment usually begins with conservative options, and its goal is to alleviate symptoms and improve the extremity appearance. Requirements for intervention therapy are the passing of 3 months of unsuccessful conservative therapy with positive venous reflux, or a state during examination which requires intervention, such as varicose vein hemorrhage. In rough, intervention therapy can be divided in open surgery and endovenous ablative procedures. Benefits of open surgery are complete removal of varicose veins, with which the problem of recanalization is eliminated. Shortfalls are the possibility of creating hematomas and ecchymoses., and longer recovery period. Moderns trends of varicose vein therapy prefer usage of endovenous ablative procedures, however open surgery remains as an excellent method of treatment.
