[Multi-vessel venous perforating varices].
Using ultrasonographic data, the author describes the existence of venous perforators communicating between deep veins and superficial veins and with several distinct channels. Perforators are classified into three types according to whether they have multiple axes on the surface, deep, or both together. There are two sub-types, A and B, of perforators with multiples axes on the surface, according to whether they join up with the same or different superficial veins. These multi-channel perforators represent a risk of failure in excision or conservative surgical treatment which may result in hemodynamic overload being imposed on another venous sector, and of the development of telangiectasia or even of veno-venous shunts. Such perforators may behave in the same way as angiomas and sclerosing injections would then be preferable to a surgical solution.
