摘　　要：目的观测不同胎龄胎儿左心房结构,分析其大小范围及变化规律,为临床疾病诊断及手术治疗提供形态学资料。方法将40例胎心标本按胎龄大小分为4组,对各组胎儿左心房内主要结构(左上、下肺静脉内径,右上、下肺静脉内径,左心房壁厚度,二尖瓣环长、长短径大小)进行观测比较,所得数据用SPSS系统处理。结果不同胎龄的平均值,左上、下肺静脉内径分别为0.41±0.18cm、0.38±0.13cm;右上、下肺静脉内径分别为0.44±0.14cm、0.43±0.14cm,心房壁厚度为0.05±0.02cm,二尖瓣环长、长短径分别为0.61±0.25cm、0.49±0.02cm。结论胎儿左心房各结构随胎龄增长呈正相关。Objective To observe the embryo heart left atrium structure of the increased ages to provide the morphology reference for the clinical diagnosis and the surgery. Methods 40 examples specimens were divided into four groups according to the embryo age to observe the composition of the left atriums （superior and inferior left pulmonary veins, superior and inferior right pulmonary veins, the diameter of atrioventricular orifice）. The data were processed with the SPSS method. Results The total means of the internal diameters of superior and inferior left pulmonary veins were 0.41 ± 0.18cm and 0.38 ± 0.13cm respectively, those of the internal diameters of superior and inferior right pulmonary veins were 0. 44 ± 0.14cm and 0. 43 ± 0.14cm respectively, the thickness of atrial wall was 0.05 ± 0.02cm, the mitral circumference and short track diameter were 0.61 ± 0.25cm and 0.49 ± 0.02cm respectively . Conclusion The structures of embryo heart left atrium change as the embryo age increases.
