Abstract

Sclerotherapy, an effective technique for the treatment of vasodilatation, exerts its therapeutic and cosmetic effects by injecting sclerosing agents into blood vessels to make them into fibrous stripes followed by absorption by surrounding tissues. Sclerotherapy is the first choice for the treatment of dilated intradermal venules, including reticular varicosities and telangiectasia, and also has good therapeutic effects on low-flow vascular malformations. Many factors can affect clinical effects of sclerotherapy, such as types of sclerosing agents, stability of foamed sclerosants and injection methods. With extensive application of sclerosing agents in clinic and improvement of the technology of manufacturing sclerosing foam, the working concentration and dosage of some sclerosing agents have reached a consensus. With development in sclerotherapy and application of newly-emerging technology such as imaging techniques, some progress in sclerotherapy has been made, providing deeper insights into the effectiveness and safety of sclerotherapy. Key words: Blood vessels; Telangiectasis; Vascular malformations; Sclerotherapy; Therapeutic uses
