羊水穿刺

目前该病的诊断是通过羊水穿刺、绒毛膜活检或脐静脉穿刺术获取胎儿细胞，经培养后进行染色体核型分析。

At present , the diagnosis of DS mainly depends on cytogenetic analysis through amniocentesis , chorionic villus sampling or puncture of umbilical vein to recovery fetal cell .

目前，常规的产前诊断方法一般是通过羊水穿刺、绒毛膜穿刺术等侵入性的方法获得标本，有引起自然流产的风险。

At present , the routine methods of prenatal diagnosis are amniocentesis and Chorionic villus , however , the procedures for obtaining these materials are invasive and not benign , and are associated with a higher risk of spontaneous abortion .
