Which condition is NOT a consequence of deep vein thrombosis (DVT)?

Skin discoloration can occur after a deep vein thrombosis (DVT) as a result of changes in blood flow and inflammation. When a DVT occurs, it can lead to post-thrombotic syndrome, which may involve various consequences including reduced venous return, valvular insufficiency, and subsequent skin changes such as discoloration due to venous stasis.

Post-thrombotic obstruction and valvular insufficiency are direct consequences of DVT, primarily due to damage to the venous valves and the formation of scar tissue that can obstruct normal circulation. Skin discoloration (though it can happen) is not a direct consequence related specifically to DVT but rather a symptom or result of the aforementioned complications over time. Therefore, identifying that skin discoloration is not a direct consequence of DVT helps clarify the nature of the other options, which are well-documented outcomes of the condition.
