What this trial studies

This interventional program offers a three-week consecutive phlebology-oriented thermal cure using the Amnéville-les-Thermes waters at the Saint-Eloy Thermal Center, followed by six months of clinical follow-up. Eligible adults have severe chronic venous insufficiency (CEAP C4a,b,c or C5) confirmed by venous Doppler and an indication for a phlebology-focused thermal cure. The protocol collects clinical safety and symptom outcomes over the immediate treatment period and during scheduled follow-up visits. The approach builds on balneotherapy practice as a lower-cost, noninvasive option alongside existing medical and surgical care.

Who should consider this trial

Good fit: Adults (≥18) with severe lower-limb chronic venous insufficiency (CEAP C4a,b,c or C5) confirmed by Doppler who can undertake a three-week consecutive thermal cure at Saint-Eloy and attend six months of follow-up are ideal candidates.

Not a fit: People without severe CVI, those unable to commit to a three-week stay or follow-up visits, or those with contraindications to thermal therapies are unlikely to benefit from this program.

Why it matters

Potential benefit: If successful, this treatment could reduce leg symptoms and skin complications from severe chronic venous insufficiency and offer a lower-cost noninvasive option.

How similar studies have performed: Previous balneotherapy research has shown modest symptomatic benefits for venous disease, but phlebology-oriented thermal cures have limited rigorous randomized trial data.
