Which clinical feature indicates the need for surgical intervention in arterial insufficiency?

• A. Intermittent claudication
• B. Pain at rest
• C. Normal pulses
• D. Mild edema

Answer: (B)

Pain at rest signals that arterial perfusion is critically reduced, not just during activity. When blood flow falls below what tissues need even at rest, the toes and forefoot may hurt at night or when lying flat. This rest pain reflects critical limb ischemia and indicates that revascularization—either endovascular or surgical bypass—is often necessary to restore blood flow and prevent tissue loss or amputation. Intermittent claudication, by contrast, is pain that happens with walking and improves with rest. It shows there is some arterial insufficiency, but it doesn’t automatically require immediate surgery unless the symptoms are severe or worsening. Normal pulses argue against significant arterial blockages causing limb-threatening ischemia. Mild edema is not a reliable sign of critical limb ischemia and can be seen with venous issues or other conditions.
