Danny Hsu: Are Elastic Compression Stockings Ineffective in Preventing Post-Thrombotic Syndrome?

Danny Hsu, President of THANZ, shared on LinkedIn about a recent article by Jean-Philippe Galanaud et al, published in RPTH Journal:

”The Great Stocking Debate: It’s Not About ‘If,’ It’s About ‘How Much’

For years, the efficacy of Elastic Compression Stockings (ECS) in preventing Post-Thrombotic Syndrome (PTS) has been controversial.

Are they ineffective, or are they just sitting in the drawer?

This RPTH Journal publication sheds more light on the debate, courtesy of Dr Jean-Philippe Galanaud’s team.

A new prespecified analysis of the CELEST trial suggests that adherence is the independent predictor we’ve been looking for.

The Data: The ‘50%’ Threshold

This double-blind trial compared PTS rates at 2 years based on how often patients actually wore their stockings.

The results reveal a clear ‘tipping point’:

  • < 50% Adherence: 38.4% PTS rate
  • 50–79% Adherence: 24.5% PTS rate
  • ≥ 80% Adherence: 27.5% PTS rate

Clinical Pearl: The “All or Nothing” Myth

Perfection isn’t required. Wearing ECS ≥50% of the time significantly decreased the risk of PTS (aOR=0.51).

Who Benefits the Most?

The study identified a specific phenotype where adherence yields the highest return.

Non-obese patients with extensive DVT (≥4 venous segments) saw a massive benefit:

  • Adherent (≥50%): 29.8% developed PTS
  • Non-Adherent: 54.3% developed PTS

Risk Factors for PTS Identified:

  • Obesity (aOR=4.73)
  • Extensive DVT (≥4 segments aOR=15.59)
  • Patient height

The Verdict:
Adherence matters, but we can be realistic with our patients.

Aiming for at least 50% wear time makes a clinically significant difference, particularly for our high-risk patients with extensive proximal DVT.

Does this data change how you counsel patients on compression adherence?”
