Haroun Gajraj: CLaCS vs Sclerotherapy – What Does the Evidence Show

Haroun Gajraj, Phlebologist and Board Member of the British Association of Sclerotherapists, shared a post on LinkedIn about a recent article by Gabriel Henrique Simoni et al., published in JVS-VL, adding:

Cryo-Laser and Cryo- Sclerotherapy

Why is your patient asking about CLaCS before you’ve had the chance to explain it?

A patient walks into your clinic having already watched a video of CLaCS: the vein map projected onto the skin, the laser, the cold air, the injection.

She’s read that it clears leg veins with less bruising and less staining than sclerotherapy. And she wants to know why you are not offering it.

In this clip from my new video, I set up the question I spend the rest of it answering…

What does the first-ever pooled meta-analysis of CLaCS against sclerotherapy alone actually show, and what does it leave out?

The headline figures tell one story.

What the comparison group in the largest trial actually received tells a very different one.

Full breakdown, including the evidence tables and the guideline positions, goes live Wednesday.

Link to the full article and video in the comments on Wednesday 12th August.”
