新生儿肝的位置及体表投影

The position and surface projection of the liver in newborns

目的 :积累年龄解剖学的形态学资料。方法 :用固定的 1 0 0例新生儿尸体对肝的位置及体表投影作了观测。结果 :90 0 %的新生儿肝的大部分位于右季肋区、腹上区、右腰区 ,小部分可达左季肋区、脐区。肝上界多数分别投影于右锁骨中线 5～ 6肋间、前正中线平剑胸结合、左锁骨中线 5～ 6肋间。肝下界分别位于右锁骨中线肋弓下2 7 1± 6 .5mm、剑突下 2 8 2± 6 .2mm和左锁骨中线肋弓下 1 8 4± 5 .0mm。结论 :新生儿肝相对较大 ,肝下缘在右肋弓下 1 3～ 40mm、剑突下 1 6～ 46mm可触及 ,与文献报道活体触诊结果差异较大。

Objective:To collect morphological data of age anatomy.Methods:The position and surface projection of the liver were observed in 100 fixed newborn cadavers.Results:The majority of the liver in 90.0% of the newborns lies in the right hypochondriac,epigastric and the right lumbar region,with small part extending to the left hypochondriac and umbilical regions.The projection of the upper liver line in the most newborns lies between the fifth and sixth ribs in the right and the left midclavicular line,and in the xiphisternal synchondrosis at anterior median,respectively.The lower liver line lies,respectively,in the right midclavicular line (27.1±6.5mm below the costal arch),the area (28.2±6.2mm below the xiphoid process)and the left midclavicular line(18.4± 5.0mm below the costal arch).Conclusion:Livers of newborns are comparatively large.The inferior border of the liver(13～14mm below the costal arch and 16～46mm below the xiphod process)can be touched,which is greatly different from vivo-plessesthesia results reported in medical literature.
