[Sigg's sclerosing therapy].

Abstract

This type of treatment involves the use of a large diameter needle (1.2 mm) in order to avoid the risk of intra-arterial injection. A very supple all-glass 2 cc syringe enables any extraluminal position of the needle to be felt and thus prevents paravascular injection. The iodinated solution used (Variglobine), at different concentrations, is injected with the leg raised. The volume injected should not exceed one cc per injection. A case involving extensive lesions may require up to ten injections per leg and per session. Strong compression obtained using reduced elasticity elastic bandages is then worn during the day. The duration of such compression varies between two and four weeks. An elastic stocking is then worn for the same length of time. Any possible intra-varicose retention products are removed by incision under local anesthesia. The risk of cutaneous hyperpigmentation is greatly reduced in this way.
