Sclerotherapy is the injection of a special drug (sclerosant) into a varicose vein. The drug irritates the walls of the vessel and subsequently causes its obliteration - replacement by connective tissue and transformation into a fibrous mass.
There are different techniques of sclerotherapy - for example, foam, echo sclerotherapy, microsclerotherapy. Each of them has its own features, and the choice of the optimal one depends on the diagnosis, comorbidities and personal preferences of the patient.
The most successful forms of varicose veins can be eliminated with sclerotherapy:- telangiectasia (“vascular asterisks”);
- reticular, or reticular varicosis;
- small diameter vein lesions.
