Abstract
Objective：To determine the relationship between hemodynamic of hepatic and portal vein blood flow and severity of fatty liver by color Doppler ultrasonography .
Methods：Blood flow of right and middle hepatic vein and portal vein of 93 fatty liver patients were measured. Its relation to the degree of fatty liver and its clinical significance was analyzed.
Results：Blood flow velocity of the veins in middle and severe fatty liver is slower the normal, and is negative correlative with the degree of fatty liver.
Conclusion：Color Doppler ultrasound is valuable in diagnosing the severity of fatty liver.
Key words：Fatty liver; Heppatic vein, Portal vein; Color Doppler ultrasonography
本文通过应用彩色多普勒超声技术，检测不同程度脂肪肝的肝右、中静脉和门静脉血流速度指标，分析探讨脂肪肝的血流动力学变化与脂肪肝病变程度的关系及临床意义。
资料和方法
一、研究对象
93例受检者均为我院03年住院患者，且经超声检查和临床检查（包括CT或MRI、血化验等）已明确诊断脂肪肝，同时排除其他肝病及心肺肾疾病，其中轻度30例、中度34例、重度29例（采用肝肾图像对比反差程度分组），男51例，女42例；年龄15～70岁，平均47.7岁。
二、仪器和方法
使用美国GE公司LOGIQ-7彩色超声诊断仪，探头频率2－5MHz。首先常规观察肝脏大小、形态及内部回声，再次确认脂肪肝的诊断，其次重点（1）于肝静脉距下腔静脉约15－30mm处，分别检测肝右、肝中静脉的最大血流速度。（2）于门静脉主干内检测门静脉的最大血流速度。（3）检测时要求检测角度保持在60°以内，同时要求患者深吸气后屏气，连续3次取一平均值。检测结果均经统计学处理。 |
