A 35-year-old male smoker presents with pain in his feet during exercise, numbness, and decreased pedal pulses. Which condition is most likely?
- Raynaud's phenomenon
- Peripheral artery disease due to atherosclerosis
- Deep vein thrombosis
- Buerger's disease (correct)
What is the primary pathological mechanism underlying the development of Buerger's disease?
What is the primary pathological mechanism underlying the development of Buerger's disease?
- Venous valve incompetence leading to blood pooling
- Spasmodic constriction of arteries in response to cold or stress
- Accumulation of cholesterol plaques in large arteries
- Vasculitis of small and medium arteries due to chemical exposure (correct)
A patient with Buerger's disease is prescribed nifedipine. What is the intended therapeutic effect of this medication?
A patient with Buerger's disease is prescribed nifedipine. What is the intended therapeutic effect of this medication?
- To reduce inflammation in the arteries
- To prevent blood clot formation
- To decrease blood pressure
- To dilate blood vessels, improving blood flow (correct)

Study Notes
- Buerger's disease is an inflammatory condition that impairs circulation to the extremities (arms and legs).
- Smoking is the key risk factor.
- Chemicals in tobacco cause vasculitis, inflammation of small and medium arteries in the arms and legs.
- Inflammation leads to scarring and occlusion of blood vessels.
- Typical patient: male, 20-50 years old, who smokes.
- Signs and symptoms:
- Claudication (pain with activity)
- Numbness and tingling
- Decreased pedal pulses
- Decreased temperature in the extremities
- Possible cyanosis
- If the disease progresses, total blockage of extremities blood flow causes tissue death.
- Gangrene may occur, leading to loss of digits or amputation.
- Diagnosis: arteriogram to visualize the inside of the arteries.
- Treatment: avoid all tobacco products; vasodilators such as nifedipine.
- Patient teaching:
- Quit smoking and cease using any tobacco products.
- Avoid extreme cold, which causes vasoconstriction and impairs blood flow.
