Phlegmasia cerulea dolens (PCD) (literally: 'painful blue inflammation'), not to be confused with preceding phlegmasia alba dolens, is an uncommon severe form of lower extremity deep venous thrombosis (DVT) that obstructs blood outflow from a vein. Upper extremity PCD is less common, occurring in under 10% of all cases.[1] PCD results from extensive thrombotic occlusion (blockage by a thrombus) of extremity veins, most commonly an iliofemoral DVT, of the iliac vein and/or common femoral vein.[2][3] It is a medical emergency requiring immediate evaluation and treatment.
