成年人肝尾状叶的超声测量与临床分析

目的超声测量正常成年人和肝病患者的肝尾状叶影像学数据，为临床超声诊断肝尾状叶病变提供形态学依据。方法对134例正常成年人肝尾状叶及34例肝病疾患者肝尾状叶进行前瞻性超声测量，分析不同性别、年龄段、身高、体重指数以及肝疾病肝尾状叶的差异。结果正常成年人肝尾状叶前后径：男性（2．174±0．416）cm、女性（2．010±0．350）cm；左右径：男性（2．899±0．322）cm、女性（2．683±0．306）cm；青年组、中年组、老年组肝尾状叶上下径、前后径分别为（5．115±0．583）cm、（2．212±0．367）cm、（4．814±0．570）cm，（2．038±0．384）cm、（4．781±0．914）cm、（1．955±0．460]cm，差异有显著性。过低、正常、超重、肥胖者肝尾状叶各径线差异无显著性（P〉0．05），正常成年人肝尾状叶上下径、前后径、左右径均小于肝病病人肝尾状叶的径线，差异有显著性（P〈0．01）。结论正常成年人肝尾状叶前后径、左右径男性大于女性，青年人肝尾状叶上下径、前后径大于中年、老年人，成年人肝尾状叶的各径线与体重指数、身高无相关性，肝病病人肝尾状叶的各径线均大于正常成年人。在肝尾状叶超声检测和其疾病诊断时应注意掌握生理性特点和疾病性差异，避免发生漏诊、误诊。

Ultrasound measurement and clinical analysis on the caudate lobe of adult liver

Objective To measure the imaging data of the candate lobe of liver with the ultrasound measurement for the normal adults and patients with liver disease to provide morphological evidence for clinical ultrasound adult caudate lobe lesions. Methods Though the method of forward-looking ultrasound measurements, we analyzed the differences between gender, age, height, weight, candate lobe of patients with liver disease form 134 cases of normal adult liver candate lobe and 34 cases of patients ？ liver candate lobe. Results The front and back diameter： man （2.174 ± 0.416） cm, woman （2.010 ± 0.350） cm and the left and right diameter： man（2.899±0.322）cm, woman （2.683 ± 0.306）cm, the men liver candate lobe were longer than those of the women. The up and down diameter and the left and right diametel： （5.115 ± 0.583） cm, （2.212 ± 0.367）cm of the young-age group liver candate lobe were longer than those of the mid-age group （4, 814± 0.570） cm, （2.038 ±0.384）cm and the old-age group： （4.781 ± 0.914） cm, （1.955 ± 0.460）cm. The differences were statistically significant. Liver caudate lobe diameters of too light, moderate, overweight, obese had no significant difference （P〉 0.05）.The up and down diameter, the front and back diameter and the left and right diameter of the normal adult liver caudate lobe were longer than those of the patients, with statistical significant differences （P〈 0.01）. Conclusions The front and back diameter and the left and right diameter of the men liver caudate lobe are longer than those of the women. The up and down diameter and the left and right diameter of the young people liver candate lobe are longer than those of the mid-age group and the old-age group. The every diameter of adult liver caudate has no connects with their weights and heights. The patient liver caudate lobe diameters are longer than those of normal adults. We should care the differences of the liver candate lobe in physiology and disease characteristics ways when we use ultrasound and its diagnosis to avoid missed diagnosis or misdiagnosis.
