Obstructive Sleep Apnea Syndrome (OSAS), characterized by repetitive episodes of partial or complete upper airway (UA) obstruction, is highly prevalent in the general population (2% in women, 4% in men). OSAS is associated with hypersomnolence and it increases the risk of cardiovascular morbidity and mortality. Its pathogenesis is largely multifactorial. In patients with chronic venous insufficiency, fluid retention contributes to this pathogenesis: during the day, fluid accumulates in the legs due to gravity ; during sleep in recumbent position, this accumulated fluid redistributes rostrally in the neck and causes upper airway narrowing and predisposes to OSAS.~The hypothesis is that a comprehensive treatment program for chronic venous insufficiency (SPA therapy) would reduce sleep apnea in patients with chronic venous insufficiency and concomitant sleep apnea Syndrome.~The objective is to assess the efficacy of a 3-week SPA therapy on attenuation of sleep apnea in this population of patients.
The purpose of this study is to determine whether 3-week of SPA therapy improves sleep apnea in patients with chronic venous insufficiency and concomitant Obstructive Sleep Apnea Syndrome (OSAS).
