What alternative gases with shorter half life can be used in foam sclerotherapy? I've had multiple liquid solutions but they just don't seem to have enough efficiency for the amount of veins I am trying to treat. Is Nitric Oxide a viable gas to use?
Foam sclerotherapy is a powerful tool that may treat almost any type of superficial pathology. When it comes to the optimal foam, it is the gas, ratio of gas to liquid, and sclerosant concentration that matter.
Generally speaking foam is not used for small superficial veins, yet large ropey veins and veins deep to the surface of the skin may effectively be treated. The most commonly used gases are room air, carbon dioxide, and mixed carbon dioxide/oxygen gas. I would choose CO2/O2 with a 1:4 liquid:gas ratio and a sclerosant capable of sustaining a foam consistency. This would offer a blend of quality foam using a bio-compatible gas with a safe profile.
Room air and CO2 can be used for foam sclerotherapy. There are specific
types of veins that necessitate foam sclerotherapy. Other types of
sclerotherapy agents are available and very effective.
Nitrous Oxide is not used for foam sclerotherapy. It is a anesthetic gas. For foam sclerotherapy you have 2 options-polidocanol or sodium tetradecylsulfate. Tetradecylsulfate is stronger than polidocanol but I feel Polidocanol is the best foaming solution.
