Which finding would NOT support a suspicion of deep vein thrombosis (DVT)?

The presence of numbness in the toes and heel of the foot would not support a suspicion of deep vein thrombosis (DVT) because this symptom typically indicates a neurological issue rather than a vascular problem. DVT primarily presents with signs related to venous congestion and inflammation in the affected area, which are typically characterized by swelling, warmth, tenderness, and pain, particularly during movement of the ankle, such as dorsiflexion.

In contrast to the other findings listed, numbness does not align with the classic symptoms of DVT. Unilateral calf edema is a common sign of DVT, as it reflects swelling due to fluid accumulation when a thrombus obstructs venous return. Warmth and tenderness over the area of thrombosis suggest localized inflammation and increased blood flow, which are also indicative of DVT. Pain on dorsiflexion, known as Homan’s sign, while not definitive, can suggest thrombosis when it is present alongside other symptoms. Therefore, the symptom of numbness is less relevant and does not support a suspicion of DVT, focusing instead on potential nerve involvement or other issues unrelated to venous thrombosis.
