目的 观察正常肝脏、肝硬化肝脏和肿瘤肝脏各分区容积的变异性。方法 收集行CT扫描的住院肝硬化病人 5 0例 ,正常对照组 4 0例 ,异常对照组 (肝右叶巨块型肝癌 ) 2 9例。分别测量正常肝、肝硬化肝的 4个分区容积和异常对照组的左外区容积 ,比较三组各值和差异。结果 正常肝和肝硬化肝左外区 ,左内区 ,右前区 ,及右后区的构成比分别为 [(16 .8± 2 .6 ) %、(15 .5± 3.3) %、(30 .5± 3.2 ) %、(31.9± 3.0 ) % ]和[(13.9± 6 .8) %、(2 0 .0± 7.95 ) %、(31.35± 5 .9) %、(30 .4± 5 .8) % ];肝硬化组、正常对照组和异常对照组三组所测的左外区容积分别为 15 9.0 0ml、15 8.97ml和 2 4 7.76ml,异常对照组与其它两组差异显著 (P <0 .0 5 )。结论 肝硬化时 ,左外区容积变化无差异 ,左内区、右前区和右后区均有明显缩小。右半肝巨大肝癌时 ,左外区容积代偿性增大。
Objective To observe the variability of the volumes of the normal liver, cirrhosis liver and tumor liver. Methods Fifty cases of hospitalized cirrhosis, 40 cases of normal control group and 29 cases of abnormal control group (right hepatic lobule hepatocellular carcinoma) were collected. The volume of the four compartments of the normal liver and liver cirrhosis and the volume of the left outer zone of the abnormal control group were respectively measured. The values and differences of the three groups were compared. Results The normal liver and liver cirrhosis left ventricle area, left internal area, right anterior area and right posterior area were (16.8 ± 2.6%), (15.5 ± 3.3)%, (30 .5 ± 3.2%, (31.9 ± 3.0)%] and (13.9 ± 6.8%), (20.9 ± 7.95)%, (31.35 ± 5.9% .8)%]. The left external volume measured in three groups of cirrhosis, normal control group and abnormal control group were 15 9.0 0ml, 15 8.97ml and 24.76ml, respectively. There was significant difference between the abnormal control group and the other two groups (P <0. 05). Conclusions There was no difference in the volume of the left external area during cirrhosis, but the left internal area, the right anterior area and the right posterior area were significantly reduced. Right hepatic giant hepatoma, the left outer volume compensatory increase.
