What is the significance of a positive Homan's sign in a clinical setting?

• A. Indicates peptic ulcer disease
• B. Suggestive of deep venous thrombosis
• C. Associated with varicose veins
• D. Indicates arterial insufficiency

Answer: (B)

A positive Homan's sign is significant as it is suggestive of deep venous thrombosis (DVT). This clinical sign is assessed by having the patient dorsiflex the foot while the knee is extended, which can produce pain in the calf if a DVT is present. The presence of such pain indicates irritation or inflammation in the deep veins, often associated with a thrombus. While Homan's sign is not a definitive diagnostic criterion for DVT, it can raise suspicion for the condition and prompt further investigation through imaging or additional assessments. It is crucial for healthcare providers to recognize this sign, especially in patients who may present with risk factors for thrombosis, as DVT can lead to serious complications like pulmonary embolism if not treated promptly. In contrast, options that refer to peptic ulcer disease, varicose veins, or arterial insufficiency do not relate directly to the Homan's sign. These conditions involve different pathophysiological processes and symptoms, making them unrelated to the significance of a positive Homan's response in the context of venous pathology.
