Deep vein thrombosis (DVT) is always a consideration when patients with asymmetric lower extremity swelling. Why is one leg. Two-point focused DVT ultrasonography of the femoral and popliteal veins can be incredibly useful in the Emergency Department when trying to narrow the differential diagnosis. Drs. Margaret Greenwood-Ericksen, Joshua Rempell, and Mike Stone provide a clear, image-based clinical reference tool on this ultrasound technique.
