[Anatomical study of the arch of the internal saphenous vein (saphena magna) in man].

The Authors present 40 dissections of the saphena magna with different branches. The variability of number is shown and they call attention to 5 cases of double vein. Two classifications are described. (MINNE, 1958; MORIN, 1970). It is very difficult to put all cases in these classifications. Later, the authors plan to show topographic marks for the saphena magna.
