Differential Diagnosis for Nonocclusive Thrombus within the Mid Left Superficial Femoral Vein
- Single most likely diagnosis
- Deep Vein Thrombosis (DVT): This is the most likely diagnosis given the presence of a nonocclusive thrombus within the superficial femoral vein. DVTs are common and can be caused by a variety of factors including immobility, trauma, cancer, and genetic predispositions.
- Other Likely diagnoses
- Post-Thrombotic Syndrome: This condition can occur after a DVT and is characterized by chronic symptoms such as swelling, pain, and skin discoloration in the affected limb.
- Venous Insufficiency: This condition occurs when the veins have problems returning blood to the heart due to valve problems or blockage, which can lead to symptoms similar to those of DVT.
- Superficial Phlebitis: Inflammation of a superficial vein, which can cause pain, swelling, and redness, but is less likely to cause a nonocclusive thrombus in the superficial femoral vein.
- Do Not Miss diagnoses
- Pulmonary Embolism (PE): Although less likely, a nonocclusive thrombus can break loose and travel to the lungs, causing a potentially life-threatening PE. It's crucial to monitor for symptoms such as shortness of breath or chest pain.
- Phlegmasia Cerulea Dolens: A rare but severe condition characterized by massive venous thrombosis, which can lead to limb ischemia and potentially gangrene if not promptly treated.
- Rare diagnoses
- Tumoral Thrombus: A rare condition where a tumor grows within the vein and can cause thrombosis.
- Venous Thoracic Outlet Syndrome: Compression of the subclavian vein between the clavicle and first rib, which can lead to thrombosis, but is less common in the superficial femoral vein.
- Antithrombin III Deficiency: A rare genetic disorder that increases the risk of thrombosis due to a deficiency in antithrombin III, a protein that helps regulate blood clotting.
