Nd:YAG Laser Plus Sclerotherapy vs Diode Laser Plus Sclerotherapy for Spider Veins and Reticular Veins

Official title: Comparative Study Between Nd:YAG Laser Combined With Injection Sclerotherapy Versus Diode Laser in the Treatment of Reticular Veins and Telangiectasias Using CLaCS Technique

Run by Ain Shams University · NCT07678697 · Data updated 2026-11-12

This study tests whether Nd:YAG laser combined with injection sclerotherapy clears reticular veins and spider veins better than a diode laser combined with injection sclerotherapy using the Cryo-Laser and Cryo-Sclerotherapy (CLaCS) approach.

Is this trial a fit for you?

Likely a good fit

Adults 18-60 with reticular veins or telangiectasias (CEAP C1) and Fitzpatrick skin types II–V seeking cosmetic treatment.

Probably not a fit

Patients with deeper venous disease, multiple prior vein treatments within 6 months, or contraindications to sclerosant may not benefit.

What this trial studies

This interventional study compares two multimodal treatments for reticular veins and telangiectasias (spider veins) using the CLaCS technique. Participants receive either Nd:YAG laser with sclerosant injections or diode laser with sclerosant injections, followed by skin cooling to reduce pain and protect the skin. The trial assesses vein clearance and safety to determine which method provides better cosmetic results. Eligible adults aged 18-60 with C1 class veins and Fitzpatrick skin types II–V are recruited at Ain Shams University in Cairo, Egypt. The study aims to improve targeted vein visualization and treatment efficacy while maintaining tolerability.

Why it matters

Potential benefit: If successful, patients could achieve greater clearance of visible veins with a safer, more tolerable procedure.

How similar studies have gone: Previous uses of CLaCS and laser-assisted sclero-therapy have shown promise for improved clearance, though direct head-to-head comparisons are limited.
