门静脉彩色多普勒超声检查在早期肝硬化中的诊断价值

Evaluation in diagnosis of compensatory phase cirrhosis with the portal vein waveforms using Color Doppler Flow Imaging (CDFI) technology

目的探讨彩色多普勒超声检查门静脉血流在早期肝硬化中的诊断价值。方法观察肝硬化患者141例,其中66例经CT或病理提示为早期肝硬化和75例经超声确诊为肝硬化失代偿门静脉高压的患者,对两组的二维肝脏显像,彩超门静脉频谱形态、流速、流量的进行对比分析。结果两组肝硬化患者的二维肝脏显像,差异有显著性;而门静脉血流流速、流量和双向波改变的频谱,差异无显著性。结论慢性肝病患者应常规对门静脉血流进行彩色多普勒超声检测比二维超声提供更多的信息,可增加门静脉高压的检出和早期肝硬化的超声诊断,当门静脉右支频谱形态显示双向波时,即应考虑门静脉高压的存在,为临床医生对病情的评估及治疗提供参考信息。

Objective To discuss the value of CDFI technology in diagnosis of compensatory phase cirrhosis with the portal vein waveforms. Methods Among 141 cases, 66 cases of compensatory phase cirrhosis were diagnosed using CT or pathology, and 75 cases of portal vein hypertension in liver cirrhosis were diagnosed utilizing ultrasound. The portal vein waveforms and velocity of flows were comparatively analysised based on the two groups. Results The diameter of the portal vein checked by two-dimensional ultrasound were statistically significant, while the portal vein waveforms and velocity of flows between two groups were not statistically significant. Conclusion Detection by CDFI which can provide more information than two-dimensional ultrasound on portal venous blood flow in patient with chronic hepatitis should be conventional done. When the portal vein waveforms were double-sided, the hypertension of portal vein should be in suspicion. CDFI may provide more information on disease evaluating and treatment.
