Jason PY - 2021 T2 - The Atlas of Emergency Medicine, 5e AB - Phlegmasia alba dolens (painful white leg, or milk leg) is caused by massive thrombosis of the iliofemoral veins and is characterized by pitting edema of the entire lower extremity, inguinal area tenderness, and a pale extremity secondary to arterial occlusion. Phlegmasia cerulea dolens (painful blue leg) arises from massive thrombosis of the lower extremity veins, including the perforators and collaterals, resulting in venous ischemia with a cool, painful, swollen, tense, and cyanotic-appearing lower extremity. Occasionally, there is bullae formation; compartment syndrome and gangrene may follow. The differential includes arterial insufficiency or thrombosis, aortic dissection, abdominal aortic aneurysm, cellulitis, and lymphedema. Doppler ultrasound and CT venography (most accurate for determining extent) are used for diagnosis.
