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。
The morphology and location of the liver of 30 newborns (male 18, female 12) were observed. The shape of the liver (front view) was divided into eight types. The type Ⅰ ~ Ⅳ accounted for 70.00 ± 8.37%. The shape of the liver nude area divided into three types; type Ⅰ accounted for 56.67 ± 9.05%. Left and right liver diameter was 100.80 ± 8.07mm, anteroposterior diameter of 42.87 ± 4.48mm, the upper and lower diameter of 63.40 ± 7.49mm, weight 130.68 ± 3.700g. Neonatal liver is relatively larger than adults. The right lobe of the liver is larger than the left lobe of the liver. Most of the liver is located in the right quarter of the rib, abdominal area and right lumbar region, a small part of the umbilical area, left quarter ribs and left lumbar region. Detailed observation of the body surface projection of the liver; neonatal liver lower than the upper and lower than adults.
