Clinical Causes: Progressive build-up of fatty deposits (plaques) within the arterial walls (atherosclerosis). Chronic high cholesterol levels promoting plaque formation. High blood pressure contributing to arterial damage. Smoking which damages blood vessels and accelerates atherosclerosis. Diabetes mellitus leading to vascular complications. Sedentary lifestyle and lack of physical activity. Obesity increasing strain on circulatory health. Genetic predisposition to vascular diseases.

Key Symptoms: Pain or cramping in the affected leg during activity (claudication). Rest pain in the foot or heel, especially at night. Tissue ulcers on the heel and midfoot that may slow healing or become infected. Skin changes such as poor skin color, shiny appearance, or loss of hair on the limb. Coldness or pallor in the leg or foot. Weak or absent pulses in the affected limb. Numbness or a tingling sensation in the foot. Delayed healing of skin injuries or wounds.

Diagnosis Path: Ankle-brachial index (ABI) measurement to assess blood flow. Doppler ultrasound to visualize blood flow and identify blockages. Angiography (such as CT or magnetic resonance angiography) to pinpoint vascular obstructions. Physical assessment of pulses, skin condition, and ulcer characteristics. Blood tests to evaluate cholesterol, blood sugar, and inflammatory markers.

Treatment Protocols: Lifestyle modifications like smoking cessation, healthy diet, and regular exercise. Medications to control cholesterol levels (statins), blood pressure, and blood sugar. Antiplatelet therapy to prevent clot formation and improve blood flow. Wound care including cleaning, dressing, and possibly debridement of ulcers. In severe cases, surgical intervention such as bypass surgery or angioplasty to restore blood flow. Use of specialized footwear or orthotics to offload pressure from ulcers. Infections may require antibiotics if ulcers become infected. Close monitoring and regular healthcare follow-ups to prevent complications.
