肝静脉超声显象诊断肝病的意义

Significance of ultrasonography of hepatic vein in diagnosis of liver diseases

目的探讨肝脏疾病肝静脉的超声显象特点及肝静脉的超声征象在肝脏疾病诊断中的意义．方法应用Ｂ型超声对１４８例（男９３例，女５５例，年龄２１岁～７６岁．肝癌、肝囊肿、肝血管瘤、肝硬变、脂肪肝、瘀血肝、布加综合征各２０例，多囊肝８例）不同肝脏疾病的肝静脉的声象图表现特征进行了观察研究．结果肝脏肿块（肝癌、肝囊肿和肝血管瘤）常导致肝静脉的受压移位；肝硬变、脂肪肝的肝静脉变细或显示不清；瘀血肝的肝静脉扩张；布加综合征肝静脉扩张、闭塞及相互交通并存；多囊肝的肝静脉结构常分辨不清．结论肝脏疾病肝静脉的超声征象具有显著的特征性，它对于临床肝脏疾病的病情分析、诊断与鉴别诊断均具有重要的临床价值和意义．

IM To study the ultrasonographic features of hepatic vein and its significance in diagnosis of liver diseases. METHODS The ultrasonic characteristics of hepatic veins in 148 patients with liver diseases (93 males and 55 females, aged from 21 to 76 years) were examined by Bmode ultrasonography. RESULTS The hepatic veins of liver mass (liver cancer, liver cyst and liver hemangioma) were compressed and moved. The hepatic veins of cirrhosis and fatty liver were thinned or not clear. The veins of liver with extravasated blood were dilated. The hepatic veins in BuddChiari syndrome were dilated, closed or crisscrossed. The polycystic liver veins were not clear. CONCLUSION The ultrasonic feature of hepatic vein in liver diseases is characteristic which is of great clinical value and significance in analysis, diagnosis and differential diagnosis of liver diseases.
