Annals of vascular surgery

Complex regional pain syndrome (CRPS), formerly known as "reflex sympathetic dystrophy," is a chronic neurological disorder characterized by disabling pain, swelling, vasomotor instability, sudomotor abnormality, and impairment of motor function. The disorder usually develops after minor trauma or surgery. No specific diagnostic test is available and, hence, diagnosis is based mainly on history, clinical examination, and supportive laboratory findings. ⋯ Early recognition and a multidisciplinary approach to management seems important in obtaining a good outcome. Treatments aimed at pain reduction and rehabilitation of limb function form the mainstay of therapy. Comorbidities, such as depression and anxiety, should be treated concurrently.
