Conditions

Venous Insufficiency of Leg

Summary

Chronic venous insufficiency (CVI) is a common progressive vascular disease that affects nearly one-third of the French population. Despite considerable advances in the treatment of chronic venous insufficiency, this condition remains a burden for patients and national healthcare systems. Balneotherapy-which includes thermal cures-is part of the therapeutic arsenal used in the treatment of chronic venous insufficiency. It is a relatively effective alternative with a relatively low cost compared to drug or surgical treatments. Phlebology is a thermal treatment orientation recognized by the French social security system. The Saint-Eloy Thermal Center is listed among the thermal stations approved by the French Ministry of Health. It currently uses thermal water from Amnéville-les-Thermes to treat rheumatological and respiratory conditions, and wants to expand its range of orientations by adding phlebology. The AMNEVILLE-PHL study therefore aims to evaluate the efficacy and safety of the Saint-Eloy thermal cure for phlebology in patients suffering from severe chronic venous insufficiency.

Interventions

OTHERPhlebology oriented thermal cure

The phlebology oriented thermal cure takes place over a period of 3 consecutive weeks, with 6 days of cure per week (Monday to Saturday, i.e. 18 days). It includes 72 treatment sessions over the 18-day period and three medical consultations (including an initial consultation, a mid-course consultation, and a final consultation) organized by the resort's thermal doctors. The treatment program is established by the thermal doctor based on the patient's clinical profile.
