The author reminds practitioners dealing with varicose disorders by means of surgery that varices of the long saphenous system are not necessarily provoked by valvular incontinence of the saphenofemoral junction. He also reminds us that, for treatment to be effective, there must above all be a completely sure diagnosis, so that appropriate surgery can be carried out in all circumstances. He also asserts that stripping is by no means a guarantee against recidivism. Further to this, he presents statistical data on the factors which lead to persistence or reappearance of post-stripping varices in the long saphenous vein, and attempts to categorize these. The author ends by showing his final conclusions.
