目的探讨酒精性肝硬化(ALC)与乙肝肝硬化(LC)患者肝脏的超声影像学特征,为两种疾病的鉴别诊断提供依据。方法采用Alako SSD4000彩色多普勒超声仪(探头频率为2.5～6.0MHz)检测69例LC和54例ALC,比较两组患者左、右肝脏厚径、门静脉内径、脾脏厚度、肝脏形态、肝脏被膜是否平滑及肝脏内部回声。结果 LC患者肝脏体积缩小、形态失常、肝被膜锯齿状改变、实质斑片状不均回声发生率及脾脏增厚程度与ALC患者比较差异有统计学意义(P<0.01);ALC患者肝脏体积增大和肝实质内弥漫性回声增强发生率与LC患者比较差异有统计学意义(P<0.01);门静脉内径两组间差异无显著性意义(P>0.05)。结论 ALC与LC有着明显不同的肝脏超声影像学特征,可作为临床鉴别诊断的依据。
Objective To investigate the ultrasonographic characteristics of liver in patients with alcoholic cirrhosis (ALC) and hepatitis B cirrhosis (LC), and to provide evidence for the differential diagnosis of the two diseases. Methods A total of 69 cases of LC and 54 cases of ALC were detected by using Alako SSD4000 color Doppler ultrasound system (probe frequency was 2.5 ~ 6.0MHz). The left and right liver thicknesses, portal vein diameters, spleen thickness, liver morphology, Whether it is smooth and internal echo of the liver. Results The liver volume of LC patients was reduced, the morphology was abnormal, the hepatic capsule serrated changes, the incidence of uneven patchy echoes and the degree of spleen thickening were significantly different from those of ALC patients (P <0.01) The incidence of diffuse echo enhancement in large and hepatic parenchyma was significantly different from that in LC patients (P <0.01). There was no significant difference between the two groups in portal vein diameter (P> 0.05). Conclusion ALC and LC have significantly different characteristics of liver ultrasound imaging, which can be used as the basis for differential diagnosis.
