A foam is described for injection treatment of varicose veins. The foam comprises a sclerosant liquid, e.g. polidocanol solution, and a gas. The gas comprises xenon, optionally together with at least one other physiologically acceptable gas which is readily absorbed in the body or blood of a patient. The gas comprises only a minimal amount of gaseous nitrogen, between 0.0001% and 0.8%. |
