新生儿肝的形态学观察

观测30例(男18、女12)新生儿肝的形态和位置;肝的形状(前面观)分八型;Ⅰ～Ⅳ型占70.00±8.37％。肝裸区的形状分三型;Ⅰ型占56.67±9.05％。肝左右径为100.80±8.07mm,前后径为42.87±4.48mm,上下径为63.40±7.49mm,重为130.68±3.700g。新生儿肝相对地比成人大。肝右叶均大于肝左叶。肝大部分位于右季肋区、腹上区及右腰区,小部分达脐区、左季肋区及左腰区。详细地观测了肝的体表投影;新生儿肝的上下界均比成人低。

MORPHOLOGICAL OBSERVATION OF THE LIVER IN NEWBORN

The shape and position of the liver are observed and measured in 30 newborn cadavers (male 18, female 12). The shape of the liver viewed from the front surface are classified into 8 types; I-IV types account for 70.0+8.39%. The shape of the "bare area" of the liver viewed from the above are classified into 3 types. Type I accounts for 56.67+9.05%. The sulcus and lobes in the lower surface of the liver already develop into form commonly. The left-right diameter of the liver ( long ) is 100.8+8.09mm. The antcrioposteripr diameler(thick) is 42.89 +4.28mm; the upper-lower diameter ( wide ) is 63.4+7.49mm; and the weight is 130.68+37.0g. The liver of the newborn is relatively major compared with that of the adult and the right lobe is larger than the let onc. The large Portion of the liver occupies the right hypochondriac, epigastric and right lumbar regions with the small Portion extending into the umbilical, left hypochondriac and left lumbar regions. The surface Projection of the liver are observed and measured with great care. The upper and lower limit of the liver is low compared with the adult.
