Which is a clinical indication for a lower extremity venous exam?

• A. Edema/swelling
• B. Chest pain
• C. Tachycardia
• D. Ulcers

Answer: (A)

Edema or swelling in the leg is a classic signal to image the leg veins. When the leg swells, a venous problem like a deep vein thrombosis or chronic venous insufficiency could be causing fluid buildup and abnormal venous flow. A lower-extremity venous exam, usually a duplex ultrasound, directly evaluates the veins for clots, obstruction, and reflux, helping confirm or rule out venous disease and guide treatment to prevent complications.

Chest pain or tachycardia point more toward heart or lung issues, not primarily a venous problem in the leg, so they’re less specific triggers for a venous study. Ulcers can be related to venous disease, but ulcers have multiple possible causes, and edema is a clearer, more direct sign that prompts venous imaging. Hence edema/swelling is the most straightforward clinical indication for a lower-extremity venous exam.
