[Echography and sclerotherapy].

Duplex-scanning represents major progress in diagnosis of venous insufficiency. It now permits also amelioration of sclerotherapy, by direct visual reference to the Doppler screen by which means we guide puncture of the vein and control the injection, whether the vein is deep or the location difficult. It permits us also to follow up the results rigorously. The video shows the injection technique by Doppler guidance. The authors report the initial results of a study of 72 consecutive cases.
