彩超检查肝硬化结节和原发性微小肝癌的临床应用及鉴别诊断价值

Clinical Application and Differential Diagnosis Value of Color Doppler Ultrasound Examination of Liver Cirrhosis Nodules and Primary Small Hepatocellular Carcinoma

目的分析彩超检查对肝硬化结节和原发性微小肝癌的临床应用及鉴别诊断价值。方法选取2019年1月-2021年1月萍乡市第二人民医院收治的50例结节性肝硬化患者。其中肝硬化结节36例,原发性微小肝癌14例,所有患者均给予彩色多普勒超声检查,比较其声像特点、血流动力学表现,并对其诊断效能进行分析。结果肝硬化结节与原发性微小肝癌的结节形态、边界、回声、包膜、占位效应、血流信号比较,差异有统计学意义(P<0.05);原发性微小肝癌患者的固有肝动脉血流峰值及最小流速均高于肝硬化结节患者,肝门静脉流速低于肝硬化结节患者,差异有统计学意义(P<0.05);彩超检查鉴别肝硬化结节与原发性微小肝癌的诊断准确性为80.00%,误诊率为20.00%。结论彩超检查可利用声像特征及血流信号检测鉴别肝硬化结节和原发性微小肝癌,诊断价值较高。

Objective To analyze the clinical application and differential diagnosis value of color Doppler ultrasound in liver cirrhosis nodules and primary small hepatocellular carcinoma.Methods Fifty patients with nodular cirrhosis admitted to the Pingxiang No.2 People's Hospital from January 2019 to January 2021 were selected.Among them,there were 36 cases of liver cirrhosis nodules and 14 cases of primary small hepatocellular carcinoma.All patients were given color Doppler ultrasonography.The sonographic characteristics,hemodynamic performance and diagnostic efficiency were compared.Results There were statistically significant differences in nodule morphology,boundary,echo,capsule,occupying effect and blood flow signal between cirrhotic nodules and primary small hepatocellular carcinoma(P<0.05).The peak and minimum velocity of intrinsic hepatic artery blood flow in patients with primary small hepatocellular carcinoma were higher than those in patients with cirrhosis nodules,and the velocity of hepatic portal vein was lower than that in patients with cirrhosis nodules,the difference was statistically significant(P<0.05).The diagnostic accuracy of color Doppler ultrasound in differentiating cirrhosis nodules from primary small hepatocellular carcinoma was 80.00%,and the misdiagnosis rate was 20.00%.Conclusion Color Doppler ultrasound examination can use ultrasonic features and blood flow signal detection to identify cirrhosis nodules and primary small hepatocellular carcinoma,with high diagnostic value.
