[Echo-guided compression sclerotherapy using foam: an improvement in the treatment of varicose veins].
Recently, echo-guided compression sclerotherapy (ECST) using foam was introduced as an efficient and patient-friendly therapy for the treatment of varicose veins. ECST enables operation under either spinal or general anaesthetic to be avoided. Foam for phlebological use is a volatile mixture of a gas, usually air, and a small quantity of liquid with the characteristics of a detergent or soap, such as polidocanol. The product that is injected has deterging properties. It reduces the surface tension of endothelial cells resulting in the destruction of the vascular wall. The treated vessel is subsequently reduced to a fibrous cord. For small calibre varicose veins, sclerosing fluids are used. In The Netherlands, until relatively recently branch varicosities of the long and short saphenous veins were treated surgically, but ECST using foam can be successfully used to treat wide calibre varicosities. Caution is advised in treating patients who are known to have a history of open foramen ovale because of the higher risk of the occurrence of scotoma and transient cerebral ischaemia.
