Successful implementation of extravascular membrane debridement for the treatment of Raynaud’s disease By the newspaper, a female patient with Raynaud’s syndrome in Guanxian County recently received the most advanced international extravascular membrane debridement in the People’s Hospital, and was successfully discharged from the hospital. A young female patient, Zhang, had a toe amputated last year due to morbidity, and recently visited the city People’s Hospital for purple hands and feet and severe pain. After receiving the patient, Li Haiqing, deputy chief physician of hand and foot surgery, asked for a detailed medical history, confirmed the patient’s diagnosis of Raynaud’s syndrome, and decided to treat the patient with extravascular membrane debridement. After careful preparation, Li Haiqing, Dai Guoguang and other medical personnel carefully peeled off the reticular fibrous tissue and outer membrane around the patient’s flexor artery and finger artery under a high-powered microscope, and blocked the sympathetic nerve fibers entering the blood vessels by peeling off the outer membrane of the distal ulnar flexor artery and finger artery, so that the blood vessels could be diastolic and the blood supply to the distal limbs could be restored. According to the introduction, Raynaud’s syndrome is a paroxysmal spasm of the arteries of the extremity. It often develops under the influence of factors such as cold stimulation or emotional excitement, and manifests as intermittent pale, cyanotic and flushed changes in the skin color of the extremities. The presence of antigen-antibody immune complexes in the patient’s serum can cause vasospastic changes through chemically transmitted substances or by acting directly on the sympathetic end plate. Medication is often ineffective and patients have numbness and tingling in the fingers and toes, which in severe cases can lead to necrosis or ulceration of the fingers and toes.
