Diaphragmatic elevation is a disease in which the diaphragm fibers are congenitally dysplastic, or the diaphragmatic nerve is paralyzed causing the diaphragm to elevate, resulting in cardiopulmonary compression and causing a series of respiratory and circulatory changes, often accompanied by paradoxical movements of the affected diaphragm, resulting in respiratory and circulatory impairment. Its etiology can be divided into congenital and acquired, mainly related to diaphragm dysplasia, genetics, trauma, infection, tumor and other diseases. Its clinical symptoms, some children feel headache and dyspnea, often with upper respiratory tract infections, asthma, cough and fatigue, also affect the digestive system and may be complicated by intermittent intestinal obstruction. In severe cases, it even leads to respiratory and circulatory failure.
