Overview
DVT is characterized by pain and swelling of the limb, which are not specific symptoms. There are other conditions that can mimic VTE such as muscle strain or muscle tear, immobilization that led to leg swelling, lymphedema, lymphangitis, chronic venous insufficiency, or cellulitis.
Differential Diagnosis
Superficial Versus Deep Vein Thrombosis
- A palpable thrombus formation is classified as a superficial venous thrombus. Clots forming in the lower leg and thigh vasculature (lesser and greater saphenous veins, respectively) or the forearm and upper arm vasculature (radial, ulnar, cephalic and basilic vein, respectively) are also superficial.
- Thrombus formation in the brachiocephalic veins, the internal jugular and the superior vena cava are classified as deep.
