Renault's phenomenon refers to a disease caused by dysfunction of blood vessels and nerves,resul-ting in paroxysmal spasms of small arteries in the limbs,obstructed blood circulation,abnormal sensation at the ends of the limbs,intermittent whitening of skin color,and subsequent flushing.Professor ZHANG Xilian treated a child with Renault's phenomenon and believed that the disease should belong to the category of"Shaoyin disease"of ty-phoid fever in traditional Chinese medicine.The key to the pathogenesis is weak blood circulation,blood deficiency leads to internal cold,and cold coagulation of meridians leads to blood and yang qi not reaching the end of the four seasons,causing symptoms such as hand and foot syncope cold.When encountering external cold,the symptoms be-come more severe.Therefore,the diagnosis is blood deficiency cold syncope syndrome.The treatment should start with warming the meridians,dispersing cold,nourishing blood,and unblocking the meridians.The classic formula Danggui Sini Tang(当归四逆汤)with modification can be used to achieve good results.
