目的评估二维彩色多普勒超声诊断仪在慢性肝病(chronic liver disease,CLD)中的诊断价值。方法以2014—2016年住院的87例CLD患者为研究对象,按照病情区分为肝炎组和肝硬化组,另外以40例健康人员作为对照组。采用彩色多普勒超声诊断仪测量受检者门静脉主干内径(PVD)、肝静脉内径(HVD)、脾静脉内径(SVD)及门静脉血流速度(PVE)。收集测量结果,并进行组间比较和分析。结果与对照组相比,肝炎组和肝硬化组患者PVD水平较高,而HVD和PVE水平较低(P<0.05);与肝炎组相比,肝硬化组患者PVD和SVD水平较高,而HVD和PVE水平较低(P<0.05)。结论采用彩色多普勒超声诊断设备对CLD患者门静脉系血管和血流参数进行检测分析具有一定的诊断意义,值得临床推广应用。
Objective To evaluate the diagnostic value of two-dimensional color Doppler ultrasound in chronic liver disease (CLD). Methods A total of 87 patients with CLD admitted to hospital from 2014 to 2016 were divided into hepatitis group and cirrhosis group, and another 40 healthy individuals were used as control group. The diameter of the main portal vein (PVD), the diameter of the hepatic vein (HVD), the diameter of the splenic vein (SVD) and the portal vein velocity (PVE) were measured by color Doppler sonography. Measurements were collected and compared and analyzed between groups. Results Compared with the control group, the patients with hepatitis and cirrhosis had higher levels of PVD and lower levels of HVD and PVE (P <0.05). Compared with the hepatitis group, patients with cirrhosis had higher levels of PVD and SVD HVD and PVE levels were lower (P <0.05). Conclusion The color Doppler ultrasound diagnostic equipment for detection of portal vein blood vessels and blood flow parameters in patients with CLD has a certain diagnostic significance, worthy of clinical application.
