Phlegmasia Cerulea Dolens: A Combined Vascular and Intensive Care Unit Case Report

Abstract Phlegmasia cerulea dolens (PCD) is a rare, life-threatening venous thrombosis with high morbidity and mortality. Management requires careful balance between conservative anticoagulation and timely surgical intervention. We report a 79-year-old male with PCD presenting with distal foot sparing and thigh swelling. Close monitoring of symptoms, clinical examination, and biochemical markers guided the decision for urgent fasciotomy. Early recognition and individualized management allowed limb salvage and full functional recovery. This case highlights the key clinical and biochemical indicators for intervention and underscores the need for further research on optimal timing for surgical intervention.
