[Chronic venous pathology: presentation of a new international classification]

The Authors present a new classification of chronic venous pathology. The first presentation was in Maui during the Congress of the North American Society of Phlebology and the second in London, during the last World Congress of International Union of Phlebology. The aim is to standardize the clinical and instrumental data to propose a common classification to all physicians. Etiological, anatomical, physiopathological and clinical findings were considered.
