What is Homan's sign associated with?

Homan's sign is specifically associated with deep vein thrombosis (DVT). It is a clinical sign that involves dorsiflexion of the foot causing pain in the calf, which may indicate the presence of a clot in the deep veins of the leg. While Homan's sign was traditionally taught as part of the clinical assessment for DVT, it's important to note that it is not considered a definitive test, as it lacks sensitivity and specificity.

In the context of the question, deep vein thrombosis is a condition where blood clots form in the deep veins, commonly in the lower extremities. Recognizing Homan's sign can aid clinicians in suspected cases, prompting further investigation through ultrasound or other imaging methods to confirm the diagnosis of DVT and to assess the need for anticoagulation therapy.

While coronary artery disease, aortic stenosis, and myocardial infarction are significant cardiovascular conditions, they are not associated with Homan's sign. Each of those conditions has distinct clinical features and diagnostic criteria that do not include this particular sign related to venous issues. Therefore, Homan's sign serves as a specific indicator signaling potential thrombosis in the peripheral circulation, underscoring its association with DVT.
