[Sclerotherapy in postphlebitic disease].

Sclerotherapy can be used for the postphlebitic syndrome as long as two important precautions are observed. First, the inflammatory phase must be resolved, usually taking one year for thromboplhebitis of the deep venous system and six months for that of the superficial venous system. Secondly, always begin progressively with small, doses, after having initially tested the effect of the sclerosing agent on a secondary vein.
