The prevalence of peripheral arterial disease (PAD) increases with age In addition to medical treatment, endovascular procedures can be performed, depending on the stage of the disease, to prevent complications and/or sequelae (relapse, functional loss of the affected limb, amputation, death), but also to relieve pain. This is a minimally invasive procedure most often performed under local anesthesia (LA), sometimes with the administration of sedatives (morphine and analgesics) to relieve pain and reduce anxiety related to the procedure. Non-pharmacological methods such as virtual reality (VR) are increasingly being used as an alternative to general anesthesia and excessive opioid use. The hypothesis is that VR could reduce pain during lower limb revascularization by endovascular surgery.
The prevalence of peripheral arterial disease (PAD) increases with age. In high-income countries, it is 5% between the ages of 45 and 49, and 18% after the age of 85. In France, nearly 1 million people are affected by this disease. In addition to medical treatment, endovascular procedures can be performed, depending on the stage of the disease, to prevent complications and/or sequelae (relapse, functional loss of the affected limb, amputation, death), but also to relieve pain. This is a minimally invasive procedure most often performed under local anesthesia (LA), sometimes with the administration of sedatives (morphine and analgesics) to relieve pain and reduce anxiety related to the procedure. Local anesthesia causes discomfort related to the operating environment (low temperature, harsh lighting, noise, supine position, arms along the body, cold, hard, narrow table), impacting patient cooperation and making the procedure difficult, with the need to take multiple X-rays and reinject potentially nephrotoxic contrast agents. It can lead to the procedure being stopped, with serious consequences (postponement, persistent or even worsening pain, amputation, death). Non-pharmacological methods such as virtual reality (VR) are increasingly being used as an alternative to general anesthesia and excessive opioid use. It has proven effective in managing pain and anxiety during various medical, surgical, and endovascular procedures. Its high-quality graphics immerse the patient; hypnotic speech and relaxing elements capture the patient's attention; breathing exercises help manage stress; and relaxing music creates a soothing atmosphere. This support ensures greater mental and physical comfort by reducing pain and anxiety. The hypothesis is that VR could reduce pain during lower limb revascularization by endovascular surgery.

The maximum intensity of pain experienced by the patient during the procedure will be measured at the end of the procedure using the numerical pain scale (EN) ranging from 0 for "no pain" to 10 for "worst pain imaginable."
Time frame: At the end of the revascularization procedure of the lower limbs by endovascular surgery
Anxiety will be measured at Baseline and just after the intervention using an EN ranging from 0 for "no anxiety" to 10 for "maximum imagined anxiety"
Anxiety will be measured at Baseline and just after the intervention using an EN ranging from 0 for "no anxiety" to 10 for "maximum imagined anxiety": a quick, easy-to-use scale that correlates strongly with Spielberger's STAI scale (Benotsch et al., 2000).
Time frame: At Baseline and just after the intervention of lower limb revascularization through endovascular surgery
Systolic Blood Pressure (SBP) in mmHg
Time frame: At Baseline before the procedure of lower limb revascularization through endovascular surgery, upon arrival in the operating room, then every 15 minutes until the end of the procedure.
Diastolic Blood Pressure (DBP) in mmHg
Time frame: At Baseline before the procedure of lower limb revascularization through endovascular surgery, upon arrival in the operating room, then every 15 minutes until the end of the procedure.
Heart Rate (HR) in cycles/min
Time frame: At Baseline before the procedure of lower limb revascularization through endovascular surgery, upon arrival in the operating room, then every 15 minutes until the end of the procedure.
Respiratory Rate (RR) in Beats Per Minute (BPM)
