ABSTRACT
Previous methods of classification of lower limb venous disease include that of Widmer,1 which categorized limbs, based on their clinical appearance. In 1994, an international consensus report under the auspices of the American Venous Forum presented the latest method of classification and grading of lower limb chronic venous disease, which was as a result of significant progress made in the field of non-invasive investigation of venous pathology with the use of electronic and computer-aided technology. This system requirement was similar to those for diagnosing peripheral arterial disease, which had long been in use.
