Chronic venous disorder (CVD) including varicose veins is very common health problem. The aim of this article is to introduce the classification of varicose veins and venous clinical severity scoring (VCSS) and Aberdeen varicose vein questionnaire (AVVQ) as objective and subjective evaluation tools. CEAP (clinical, etiologic, anatomic, pathophysiologic) classification is basic descriptive classification of varicose veins. It was adopted worldwide to communicate between clinicians about CVD and serve a basis for more scientific analysis. VCSS is useful assessment method of severity evaluation of CVD. It can be very useful in results assessment quantitatively. VCSS was designed not to replace of CEAP classification but, to supplement it. AVVQ is patient- reported quality of life measurement system. It is a valid and reliable outcome measurement for patients with varicose veins. These classification & measurement systems, based on correct diagnosis, were also to serve as a systematic guide of patients with CVD as an orderly documentation system and to help for decision making of appropriate treatment.
