After a brief anatomical reminder, the author discusses the place of surgery of the perforating veins in chronic venous deficiency, in three distinct aetiological and clinical circumstances: A first-hand prospective study of 220 successive operations for primary varices is analysed. In 14.5% of the cases, ligation of the perforators was associated with the stripping. In a retrospective analysis relating to 100 surgical reoperations on primary varices, the ligation of the perforators was associated with a different procedure in 13 of these patients. Finally, the author specifies the place of surgery of the perforators in the treatment of post-phlebitic syndrome. As regards the relapsing ulcer, 81% of the patients who had benefitted from this procedure never suffered relapsed ulcers (27 patients).
