Indications for Foam Sclerotherapy

According to the 2003 European Consensus Meeting on Foam Sclerotherapy, most participants limit their use of foam sclerotherapy to very large veins and recurrent varicose veins while others limit their use to very small veins. Those who treated small veins were more likely to use the Monfreux method (less viscous foam), and those who treated the larger veins were more likely to use the Tessari method (more viscous foam) [15]. However, regardless of the decided method, it should be noted that veins that are larger in diameter require a more viscous foam and, inversely, veins that are smaller in diameter should be injected with a more liquid foam [15, 18, 19].
