A person with a two hour history of phlegmasia cerulea dolens Phlegmasia cerulea dolens (PCD) is an uncommon severe form of lower extremity deep venous thrombosis (DVT) that obstructs blood outflow from a vein. PCD results from extensive thrombotic occlusion of extremity veins, most commonly an "iliofemoral" DVT of the iliac vein and/or common femoral vein. It is a medical emergency requiring immediate evaluation and treatment. When a thrombus occludes an extremity vein, pressure backs up in the venous system leading plasma fluid to leak out into the interstitium of the affected limb. This increases the pressure of that limb compartment, which can collapse the arteries and lead to acute ischemia, gangrene, hypovolemia, and hemodynamic instability. https://t.me/joinchat/AAAAAEIMp_P_-52SlidzHg
