1. A microfoam comprisinga gas component comprising a physiologically acceptable blood dispersible gas comprising 10 to 90% vol/vol carbon dioxide or a mixture of 10 to 90% vol/vol carbon dioxide with the remaining gas oxygen,and an aqueous sclerosant liquid suitable for use in sclerotherapy of blood vessels,wherein the microfoam has a density ranging from 0.07 g/ml to 0.19 g/ml.
