[Long-term results of anti-reflux surgery of the popliteal vein].

The pathophysiological cause of chronic venous insufficiency with trophic dermal changes is a valvular lesion in the deep and perforating venous system which develops in as many as 72% during recanalization of thrombi. The reduction of reflux by valvuloplasty in the popliteal section with discontinuation of the insufficient perforating vessels (sclerotization) leads promptly not only to marked subjective relief, but on a long-term basis it improves the trophic state of the skin and healing of refractory ulcerations. The technique of valvuloplasty by invagination of the venous wall after its prolongation by the axillary vein with a functional valve rules out venotomy and the use of alien material for suture which would damage the intima, and thus reduces to a minimum the possibility of postoperative thrombosis.
