The registry criteria, word for word

Show all 6 criteriaShow less

Who can take part

  • Age ≥ 18 years
  • Patients with a confirmed diagnosis of PAOD, seen either during hospitalization or in an outpatient vascular medicine consultation. Inclusion is permitted regardless of the disease stage (according to the Leriche and Fontaine classification) or prior surgical intervention
  • No objection to the use of their pseudonymised medical data
  • Polygraphy scheduled as part of routine care within one month

Who cannot take part

  • History of OSAS diagnosis confirmed by polygraphy, and currently receiving nocturnal treatment (e.g., Continuous Positive Airway Pressure - CPAP)
  • Inability to perform the Ankle-Brachial Index (ABI) or sleep polygraphy due to physical or cognitive constraints (e.g., severe dementia, limb malformation, etc.)

About the trial

What the trial wants to find out

Obstructive sleep apnea syndrome (OSAS) is characterized by partial (hypopnea) or complete (apnea) obstruction of the upper airways, leading to intermittent hypoxemia and sleep fragmentation. Peripheral arterial occlusive disease (PAOD) is a chronic condition defined by the narrowing or occlusion of arteries in the lower limbs, often resulting in ischemia of downstream tissues. This disease is a common complication of atherosclerosis and affects approximately 1.2% of the general French population.

OSAS is a well-established risk factor for atherosclerotic disease, particularly for coronary and neurovascular events. Although a relationship between OSAS and PAOD has been investigated in recent years, the link has not been definitively established and requires further study. Therefore, this preliminary cohort study aims to observe the prevalence of OSAS among patients diagnosed with PAOD, regardless of the disease stage.

The group in the trial

  • Patients with PAOD

    Patients hospitalized or seen in vascular medicine consultation with a diagnosis of PAOD at all stages (operated or not) according to the Leriche and Fontaine classification.
