[Attempt at quantification of the clinical picture of varices for epidemiologic, therapeutic and data-processing...

The expression "presence of varices" does not mean it is possible to anticipate their importance. The use of qualifications such as large, average or small by no means solves the problems of their evaluation for they often take on a different meaning according to the interpretation of the observer. The authors suggest the use of a system of clinical evaluation whose chief characteristic is the measurement of the diameter of varices. In the field of epidemiological studies, quantification is subjected to the determination of a coefficient of maximal invasion (CMI). This is equal to the product of the maximal diameter (MD) of the varices present, by their total length (TL). CMI = MD X TL. The clinical quantification for therapeutics, that is, the quantification that can be used in daily practice, is more simple. It is achieved by the intermediary of three parameters the maximal diameter, the maximal number and height of the varices present in each area. The regular analysis of these three variables makes it possible to follow in figures, and therefore in a way which is readily transmissible, the mode of evolution of the varicose disease. Generally, this quantification completes the usual schemas, makes the teaching of sclerotherapy much easier, makes phlebology more accessible for computer data, with cartography as a basis for the anatomical reference points. The main interest in these two systems lies in the use of a simple language which can be easily understood by everyone, whatever their nationality, and this makes for a more exact appreciation of the work that has been carried out and results in much better communication.
