Which is a classic sign of deep vein thrombosis (DVT)?

• A. Unilateral Leg Edema
• B. Bilateral Leg Edema
• C. Chest Pain
• D. Headache

Answer: (A)

Unilateral leg edema is the classic sign of a deep vein thrombosis because a clot in a deep vein obstructs venous return from the affected leg, causing swelling that does not appear in the other leg. The edema often comes with warmth and tenderness along the vein. If both legs are edematous, it points more toward a systemic issue such as heart failure, liver or kidney disease, or venous insufficiency, rather than a DVT in one leg. Chest pain can signal a cardiopulmonary problem like myocardial infarction or pulmonary embolism, but it’s not the typical presenting sign of DVT itself. Headache isn’t related to DVT. When unilateral leg edema is suspected for DVT, a duplex ultrasound is the common confirmatory test, guiding treatment with anticoagulation if positive.
