彩色多普勒超声对原发性肝癌肝内转移灶的诊断价值

The diagnostic value of color doppler ultrasound in the liver metastasis of primary hepatocellular carcinoma

目的:探讨彩色多普勒超声诊断原发性肝癌肝内转移灶的临床价值。方法:选取临床确诊的原发性肝癌患者60例,术前使用彩色多普勒超声对原发性肝癌周边区域及肝内进行观察,重点观察原发肿瘤周边≤3c m区域有无转移灶,计算彩色多普勒超声诊断转移灶的特异性和灵敏性。结果:60例患者中,超声诊断有38例转移灶。转移灶共计48例,原发性肿瘤周边≤3cm区域转移灶42个;转移灶超声特征:转移灶平均直径1.1±0.2cm;形态呈圆形或椭圆形;内部呈多成低回声为主39例(81%);48例转移灶中,彩色多普勒检查26(54%)例转移灶有血流信号,22例转移灶无血流信号;彩超诊断转移灶的特异性54.54%,灵敏性89.47%,准确性76.67%。结论:彩色多普勒超声对肝癌转移灶有一定的准确性,可作为术前判断肝内转移灶的筛选方法。

Objective To discuss the diagnostic value of color doppler ultrasound in the liver metastasis of primary hepatocellular carcinoma. Methods 60 patients with primary liver cancer were selected; Color Doppler ultrasound was used to observe the surrounding area and liver of primary liver cancer before operation. The key observation of primary tumor surrounding area was less than or equal to 3 cm with or without metastasis, calculation of color Doppler ultrasound in the diagnosis of metastatic specificity and sensitivity. Results Of the 60 patients, 38 were diagnosed by metastases. A total of 48 cases of metastasis, primary tumor surrounding area 42 metastases less than 3 cm; Features of Metastasis ultrasound: The average diameter of metastasis was 1.1±0.2 cm; the shape is round or oval; there were39 cases(81%); In 48 cases of metastases, color Doppler examination showed that 26(54%) patients had blood flow signals, and 22 patients had no blood flow signals; The specificity of color Doppler ultrasound in diagnosis of metastasis was 54.54%, sensitivity was 89.47%, and accuracy was 76.67%. Conclusion Color Doppler ultrasound has certain accuracy in the metastasis of liver cancer, and it can be used as a screening method for preoperative diagnosis of intrahepatic metastasis.
