Which physical exam finding is commonly observed in a patient with DVT?

Calf tenderness is a commonly observed physical exam finding in a patient with deep vein thrombosis (DVT). This tenderness is often a result of inflammation in the venous system caused by the thrombus, or blood clot, within the deep veins of the leg. The localized tenderness can usually be reproduced by palpation of the calf and is often accompanied by other signs, such as swelling and a possible increase in local warmth.

In the context of DVT, the pathophysiology involves blood clot formation that can lead to obstruction of venous return, resulting in increased venous pressure and subsequent swelling. The inflammatory response initiated in the area can further contribute to tenderness as well as pain when the affected area is touched or manipulated. Recognition of calf tenderness during a physical examination is significant for the suspicion of DVT, as it can help guide further diagnostic evaluation.

Other findings such as a skin rash, joint swelling, or cold extremities are typically not associated with DVT and could suggest different conditions or pathologies. The presence of these findings does not align with the typical signs of a thrombotic event in the deep venous system. Therefore, calf tenderness stands out as a classic symptom indicative of the condition.
