1866年Down首次描述了先天愚型。1959年证实它与21—三体有关。该征有与智力受限相对恒定的表型,主要特征为颅面畸形。确诊有赖于核型分析。该综合征患儿常有先天心脏畸形。本文报道先天愚型患儿伴先天性心脏病(先心病)的性别分布差异,并与一般人群的先心病性别分布进行对照。285例疑有先心病的先天愚型患儿,均记录其畸形类型和性别等。结果285例疑有先心病的先天愚型患儿中,男性124例(43.50%),女性161例(56.50%)。18例因诊断不确切而排除。同期一般人群中怀疑有先心病
Down, 1866, first described Down’s syndrome. It was confirmed in 1959 with the trisomy 21. This sign has a relatively constant mental retardation phenotype, the main feature of craniofacial deformity. Diagnosis depends on karyotyping. The syndrome often congenital heart malformations. This article reports the gendered distribution of congenital heart disease (congenital heart disease) among children with congenital obesity and compared it with the sex distribution of congenital heart disease in the general population. 285 cases of congenital obesity in children suspected of congenital heart disease, were recorded the type of deformity and gender. Results Among 285 patients with congenital heart disease who were suspected to have congenital heart disease, 124 (43.50%) were male and 161 (56.50%) were female. 18 cases were excluded due to inaccurate diagnosis. Over the same period the general population suspected of having congenital heart disease
