Which sign suggests a possible DVT upon examination of the calf?

The presence of palpable cords in the calf during examination is indicative of a possible deep vein thrombosis (DVT). Palpable cords may represent thrombosed veins, which can be a sign of the formation of a clot that obstructs normal blood flow. When examining a patient for DVT, healthcare providers assess for signs such as swelling, tenderness, and changes in skin temperature, along with any palpable mass or cord-like structures in the veins of the affected limb.

In contrast, full range of motion indicates that the patient can move the calf joint without restrictions, typically suggesting the absence of significant issues, which does not support the suspicion of a DVT. No tenderness suggests that the calf is not inflamed or painful, making DVT less likely. Finally, no swelling again points towards the absence of one of the classical signs of DVT, which is often the initial observable manifestation. Thus, when palpable cords are present, they become a critical sign pointing toward the likelihood of a DVT.
