Which signs and symptoms are associated with arterial insufficiency?

• A. Pallor, intermittent claudication
• B. Pedal edema, brown pigmentation
• C. Blanched skin, lower extremity ulcers
• D. Peripheral neuropathy, cold extremities

Answer: (A)

Pallor and intermittent claudication are classic signs and symptoms associated with arterial insufficiency. When blood flow through the arteries is reduced, patients often exhibit pallor, especially during activities that increase oxygen demand, such as exercise. This is because the poorly perfused muscles receive inadequate oxygenated blood, leading to symptoms such as claudication, which presents as cramping or pain in the legs or buttocks during physical activity that typically resolves with rest. Together, these signs indicate compromised arterial circulation and help in diagnosing conditions related to arterial insufficiency.
