Differential Diagnosis for DVT
- Single Most Likely Diagnosis
- Deep Vein Thrombosis (DVT): This is the most likely diagnosis given the presentation, as DVT is a common condition that can cause symptoms such as leg swelling, pain, and warmth.
- Other Likely Diagnoses
- Cellulitis: An infection of the skin and subcutaneous tissue that can cause similar symptoms to DVT, such as redness, swelling, and warmth.
- Musculoskeletal injury: A muscle or tendon injury can cause pain and swelling in the affected leg, mimicking DVT symptoms.
- Lymphedema: A condition characterized by chronic swelling of the leg due to impaired lymphatic drainage, which can be mistaken for DVT.
- Do Not Miss Diagnoses
- Pulmonary Embolism (PE): A potentially life-threatening condition that can occur if a DVT breaks loose and travels to the lungs, making it crucial to consider and rule out.
- Phlegmasia Cerulea Dolens: A rare but severe condition caused by extensive DVT, leading to limb ischemia and potentially gangrene.
- Compartment Syndrome: A condition characterized by increased pressure within a muscle compartment, which can cause severe pain, swelling, and potentially permanent damage if not promptly treated.
- Rare Diagnoses
- Popliteal Artery Aneurysm: A rare condition where the popliteal artery becomes dilated, potentially causing leg swelling and pain.
- Cystic Adventitial Disease: A rare condition characterized by the formation of cysts within the adventitia of the popliteal artery, leading to leg pain and swelling.
- Thoracic Outlet Syndrome: A rare condition where the nerves and/or blood vessels between the neck and shoulder become compressed, potentially causing arm and leg symptoms.
