• In trained hands it is simple, affordable, safe, efficient and easily repeatable.

• Ideal sclerosing must ensure appropriate concentration of the agent with integral contact to the entire venous wall.

• Liquid sclerosing agent gets washed away by blood quickly when the vein diameter is over 3 mm.

• Injection with foam has the advantage of filling the vein and staying longer and causing spasm.

• In the past attempts were made to clear the blood from the vein, prior to injection by using “air block” technique, i.e.; injecting air before the sclerosant.

• Cabrera introduced foamed sclerosant in 1997 using CO2.
• Tessari simplified using liquid sclerosant into foam using two syringes and a three-way stopcock in 2000.

• Only detergent sclerosing agents such as Sotradecol and Polidocanol can be used to foam. One part of sclerosant with four parts air is used with two 5 CC syringes. Foam can be used in different size of the veins using concentration from 0.25% to 3%.

• Multiple, repeated treatment may be necessary and therefore results should be assessed from a life-long point of view, rather than ablation of target vein alone.

• Success of foam is attributed to its prolonged contact with the vein wall endothelium.This leads to sub endothelial layer exposure and irreversible venous fibrosis.

RESULTSRESULTS
• Primary occlusion is better than 80% in most published data. Initial failure can be treated with repeated injection, thus approaching over 95% success.

• Complications are rare, occasional DVT of the muscular veins have been reported making the incidence to be 0.03%.

• Ophthalmic migraine, visual disorders such as transient hemianopsia and dry cough are more common. Patients with patent foramen ovale have these occur more frequently.
• One death due to stroke has been reported.
