Which sign would most likely be positive in a case of DVT?

• A. Patellar tap sign
• B. Baker’s sign
• C. Homan’s sign
• D. Pitting edema

Answer: (C)

In a case of Deep Vein Thrombosis (DVT), Homan's sign is most commonly referenced as a potential indicator. This sign is positive when there is pain in the calf upon dorsiflexion of the foot, which may suggest the presence of a clot in the deep veins of the leg. The rationale behind this is that the dorsiflexion of the foot can stretch the calf muscles and the tissues surrounding the deep venous system, potentially causing discomfort or pain if a clot is present.

While Homan's sign may not be definitive and is not always reliable in clinical practice, it has been historically noted in teaching and assessments concerning DVT. In contrast, the other signs such as the patellar tap sign, Baker’s sign, and pitting edema are not specifically indicative of DVT. The patellar tap sign is related to knee effusion, Baker's sign pertains to a popliteal cyst, and pitting edema generally refers to fluid retention in the tissues but doesn't directly point to a DVT diagnosis. Therefore, Homan's sign remains the most relevant choice linked to DVT symptoms.
