title: Results of a questionnaire regarding improvement of 'C' in the CEAP classification.
abstract: BACKGROUND
  One of the shortcomings of the CEAP classification is that some of the clinical conditions in the original version were not defined and, therefore, were used in different ways by those who work with CEAP.
  
  
  OBJECTIVE
  To clarify the definitions of the seven clinical classes in the CEAP classification and to improve universal understanding of these in phlebology.
  
  
  METHODS
  The authors prepared a short questionnaire regarding the 'C' part of CEAP with five main questions, dealing with definitions of clinical items: telangiectases, corona phlebectatica, reticular veins, varicose veins and the use of CEAP. The questionnaire was translated into 11 different languages and sent around the world by means of International Venous Digest by fax. Two hundred and six answers were received from 67 countries out of 3681 faxes sent (5.6%).
  
  
  RESULTS
  There were a wide variety of opinions returned thus demonstrating that the same term is used with various meanings by different physicians. All physicians classify telangiectases of thigh and foot as class C1, but discrepant answers were obtained concerning the differences between reticular veins and reticular varicose veins as well as the diameter of small and large varicose veins. Sixty per cent of physicians answering this survey use the CEAP classification.
  
  
  CONCLUSIONS
  Further clarification and refinement of the CEAP classification are necessary. The authors hope that this will result in broader acceptance of CEAP.
