[Scleroses of the junction of the internal and external saphenous veins. New approach].

Sclerotherapy of sapheno-femoral and sapheno-popliteal junctions has been accepted for many years. However, the author points out the present tendency to refer more and more of those cases to surgery on account of the inherent dangers of such injections and of the difficulty to achieve a solid and long lasting sclerosis. He describes present variations in technic of injection, explains how he discovered a more efficient method: introducing the needle some six cm below the junction and injecting while an assistant (or a free finger) compresses the junction. He describes its applications and enumerates short and long term advantages of this technical refinement.
