Which of the following is a non-invasive measure used in PVD limb care?

• A. Skincare of feet and legs
• B. Diet counseling only
• C. Catheter-based intervention
• D. Surgical bypass

Answer: (A)

In managing peripheral vascular disease, protecting and caring for the skin of the feet and legs is a foundational non-invasive practice. When blood flow to the limbs is reduced, the skin becomes more vulnerable to dryness, cracking, and ulcers, which can lead to infection and even long-term disability. Regular skincare helps preserve skin integrity, makes early injuries visible, and supports healing.

Key aspects include daily inspection of the feet and legs, gentle cleansing and thorough drying, moisturising to prevent cracking (while avoiding excessive moisture between toes in susceptible individuals), careful nail care, and wearing protective, well-fitting footwear. These steps are simple, non-invasive, and directly target limb preservation.

The other options involve invasive interventions or broader risk-factor modification. Catheter-based interventions and surgical bypass aim to restore blood flow surgically or endovascularly, which are invasive. Diet counseling, while important for overall vascular health, does not address skin protection or ulcer prevention as a direct limb-care measure.
