[Sclerotherapy of perforating veins. Technics, doses]

The majority of perforating veins react to the sclerosant treatment in the same way as the neighbouring varicose veins. The sclerosant treatment is therefore carried out in the majority of cases as if they did not exist. But in 15% of essential varices, and in 21% of post-phlebitic varices, it is altogether different. The dose of the product necessary to achieve sclerosis of these haemodynamically significative perforators (H.S.P.) is going to be 30% or more above the dose necessary to achieve sclerosis of the neighbouring varicose sections. This relative sclero-resistance often tallies with the other methods of revealing an incontinent perforator.
