Peripheral Vascular Disease: Causes & Physiotherapy Care

Best Peripheral Vascular Disease Treatment in Delhi

What is Peripheral Vascular Disease ?

Peripheral Vascular Disease (PVD), often referred to as Peripheral Artery Disease (PAD) when it specifically affects arteries, is a common circulatory condition where narrowed blood vessels reduce blood flow to the limbs, most commonly the legs. This reduced blood flow can cause various symptoms and, if left untreated, can lead to serious complications.

Causes of Peripheral Vascular Disease

The primary cause of PVD is atherosclerosis, a condition where fatty deposits (plaque) build up inside the artery walls, causing them to narrow and harden. This plaque reduces the amount of blood flow to the limbs, decreasing the oxygen and nutrients supplied to the tissues.

Other causes and contributing factors include:-

Diabetes: High blood sugar levels can damage and weaken blood vessels over time, making them more prone to narrowing.
Smoking: Tobacco use significantly increases the risk of PVD and can accelerate its progression, as it damages blood vessel walls and promotes plaque buildup.
High Blood Pressure (Hypertension): Damages arteries, making them more susceptible to atherosclerosis.
High Cholesterol: Contributes to the formation of plaque in the arteries.
Obesity: Increases the risk of developing diabetes, high blood pressure, and high cholesterol, all risk factors for PVD.
Age: The risk of PVD increases with age, especially after 50.
Family History: A family history of PVD, heart disease, or stroke increases your risk.
Blood Clots (Thrombosis): A blood clot can lodge within a blood vessel, causing an obstruction.
Infection: Certain infections (e.g., syphilis, salmonellosis) can lead to inflammation and scarring of blood vessels.
Arteritis: Inflammation of the arteries, sometimes due to autoimmune diseases.
Injury to the Limbs: Trauma can damage blood vessels.
Unusual Anatomy of Muscles or Ligaments: Can sometimes lead to compression of blood vessels.
Blood Vessel Spasms: Conditions like Raynaud’s disease can cause temporary narrowing of blood vessels.

Symptoms of Peripheral Vascular Disease

Leg numbness or weakness
Coldness in the lower leg or foot, especially compared to the other side
Sores on the toes, feet, or legs that won’t heal
A change in the color of the legs (pale, bluish, dark reddish discoloration)
Hair loss or slower hair growth on the legs and feet
Shiny skin on the legs
Slower growing toenails
A weak or absent pulse in the legs or feet
Pain at rest, often in the toes or feet, especially at night when lying flat (indicating more severe disease)
Erectile dysfunction in men
Fatigue or aching in the arms, particularly with activity, if the arms are affected.
Gangrene (tissue death due to lack of blood flow), which can lead to amputation in severe cases.

Advanced Physiotherapy for Peripheral Vascular Disease

Supervised Exercise Therapy (SET):
- Walking Program: This is considered the most effective conservative management. Patients are encouraged to walk until they experience moderate pain (claudication), then rest until the pain subsides, and then resume walking. This “stop-start” method helps to stimulate the development of collateral circulation (new blood vessels that bypass the narrowed ones). Sessions typically last 30-45 minutes, 3-5 times a week, for at least 12 weeks.
- Treadmill Training: Often used in a supervised setting, allowing for controlled progression of intensity (speed and incline).
- Cycling/Ergometry: Can be used as an alternative or alongside walking, particularly for those who find walking too painful initially.
- Resistance Training: Strengthening exercises for leg muscles can improve walking performance and overall function.
- Yoga and Tai Chi: These mind-body practices can improve flexibility, balance, and overall well-being, which can be beneficial for PVD patients.
Pain Management Techniques
- Transcutaneous Electrical Nerve Stimulation (TENS): Can help alleviate pain by interfering with pain signals.
- Low Intensity Laser Therapy (LILT): May promote healing and reduce pain in certain cases.
- Cryotherapy/Heat Therapy: Applied locally to help manage discomfort, though caution is advised with severe circulatory compromise.
Wound Care and Edema Management:
- Compression Therapy: Graduated compression stockings or pneumatic compression devices can assist with venous return and reduce edema, especially in cases with a venous component.
- Elevation of Limbs: Elevating the affected limbs (especially when resting or sleeping) can help reduce swelling.
- Therapeutic Ultrasound: May be used to promote tissue healing in non-healing wounds.

Manual Therapy in PVD

Gentle Lymphatic Drainage Massage: If there is associated lymphedema or swelling, very light, superficial strokes can help reduce fluid buildup. This should be performed by a trained therapist.
Myofascial Release: Gentle techniques to release tension in muscles and fascia surrounding the affected limbs, which might be tight due to guarding or altered movement patterns. This can indirectly improve circulation and comfort.
Joint Mobilizations (Grade I-II): Non-thrust mobilizations to improve joint range of motion, particularly if stiffness has developed due to inactivity. This is done to improve overall mobility and facilitate more effective exercise.
Soft Tissue Mobilization (Light): Gentle effleurage (light stroking) or kneading techniques, away from affected arteries, to improve superficial circulation, reduce muscle soreness, and promote relaxation. This needs to be extremely gentle and avoid any direct pressure on arteries that might be occluded or vulnerable.
Neural Mobilization: Gentle techniques to improve the mobility of peripheral nerves, which can be affected by reduced blood flow (leading to neuropathy symptoms like numbness or pins and needles).
