In recent years, common congenital heart disease has gradually become familiar to clinicians, however, common congenital lung diseases are often not enough attention, delay diagnosis and treatment, now the main congenital lung disease in adults is discussed. First, congenital lung dysplasia Embryos from the foregut to the ventral from the foregut to the laryngeal groove and evolved into pulmonary buds in the fourth week, the lung bud is divided into two bronchial buds, bronchial buds about the first 6 weeks Leaves, the right lung points three leaves, the left lung points two leaves.
