Which long-term complication can contribute to poor extremity circulation and possibly amputation?

• A. Arteriosclerotic disease
• B. Osteoarthritis
• C. Asthma
• D. Migraine

Answer: (A)

Arteriosclerotic disease causes narrowing and stiffening of arteries, which reduces blood flow to the limbs over time. When perfusion to the extremities is chronically compromised, tissues can become ischemic and heal poorly. This sets up a cascade of problems—from painful symptoms and non-healing ulcers to infection and, in severe cases, gangrene—that may necessitate amputation to prevent life-threatening consequences. Understanding this helps explain why long-term vascular disease is a key factor in poor extremity circulation and potential limb loss.

The other conditions don’t directly create the chronic arterial narrowing that leads to limb ischemia. Osteoarthritis affects joints, not blood flow to the limbs. Asthma involves the airways, and migraines are vascular/neurovascular headaches, not peripheral arterial disease.
