On physical examination, the patient had acute phlegmasia cerulea dolens (painful blue edema) of her left lower extremity (Figures 1 and 2) secondary to extensive bilateral deep vein thrombosis (DVT) up to the proximal common iliac veins. Occlusive deep vein thrombosis of right common femoral vein (Figure 3) and that of left external iliac vein (Figure 4) are visible on Doppler ultrasound.
