The early manifestation of Raynaud’s phenomenon is generally characterized by paroxysmal symmetrical intermittent whitening, cyanosis and flushing of the extremities (mainly the fingers), which can gradually develop to the palms of the hands. Raynaud’s phenomenon, also known as Raynaud’s syndrome, is a vascular neurological dysfunction caused by small arterial spasm of the extremities, paroxysmal limb extremities (mainly fingers) symmetrical intermittent whitening, cyanosis and redness as its clinical features, often for emotional and cold induced. Raynaud’s syndrome is a vascular neurological dysfunction that occurs under the influence of multiple factors and is usually secondary to other diseases, such as systemic lupus erythematosus, scleroderma, and thromboembolic vasculitis. Typical episodes of Raynaud’s syndrome are divided into three phases. At first pallor, paroxysmal spasm of small arteries, finger or toe end local ischemia caused by the onset of local temperature reduction or numbness, stiffness, if the motor nerves are affected can also cause movement disorders and excessive sweating. Then cyanosis, after a few minutes of small arterial spasm relief, capillary dilatation passive congestion and cyanosis. Finally, flushing, small arteries re-dilatation, circulation re-establishment and reactive congestion flushing and swelling. It is recommended that people with Raynaud’s syndrome should go to the hospital in time and standardize the treatment under the guidance of the doctor.
