CLaCS Using 0.2% Aetoxysklerol Foam and 70% Glucose for the Treatment of Lower Limb Telangiectasias

This randomized, controlled, non-inferiority trial aims to compare the efficacy of two sclerosants used in the CLaCS (CryoLaser and CryoSclerotherapy) method for treating telangiectasias and reticular varicose veins. CLaCS is an advanced outpatient procedure that combines Nd\\:YAG laser treatment with sclerotherapy to enhance vein closure and cosmetic outcomes while minimizing side effects. The trial will compare the standard 70% glucose sclerosant with a novel 0.2% Aetoxysklerol (polidocanol) foam prepared using the VARIXIO system. Despite widespread use of CLaCS, no head-to-head studies currently exist comparing these two agents. This study aims to determine whether low-concentration Aetoxysklerol foam is non-inferior to 70% glucose in achieving effective telangiectasia elimination.
