[Mechanisms and effects of recurrences following active treatment of insufficient perforating veins].
In this study we examine the mechanisms and effects of relapse of incompetence perforating veins occurring after sclerosant injections or surgical operations involving ligation or removal. Five relapse mechanisms are anticipated: 1) faulty surgical technique, 2) sclero-resistance or recanalization of injected perforated, 3) dilatation of healthy perforators as a result of persistent vertical saphenous reflux, 4) growth, forced by the same disorders, of newly formed perforators. There are also "pseudo-successes", when the treated perforator is part of a "deprived saphenofemoral circulation" and is destined to right itself spontaneously after the suppression of the vertical reflux which had dilated it; and there are "pseudo-failures" too, when relapse occurs after the reestablishment of a good local vascular-tissular equilibrium and continues to be well tolerated by the surrounding skin for a very long time.
