目的探讨肝硬化患者门静脉主干内径与肝功能Child-Pugh分级及肝性脑病的关系。方法 106例肝硬化患者,肝脏彩超检查门静脉主干内径,采用Child-Pugh分级标准进行肝功能分级,分析患者门静脉主干内径与肝功能ChildPugh分级以及肝性脑病程度间的相关性。结果肝硬化患者门静脉主干内径与肝功能Child-Pugh分级无相关性,但随患者肝脏储备功能减退,肝性脑病发生率增加(P<0.01);肝硬化合并肝性脑病患者门静脉主干内径较无肝性脑病者增宽(P<0.05),但不同程度肝性脑病患者间门静脉主干内径比较差异无统计学意义(P>0.05)。结论根据门静脉主干内径可预测肝硬化患者肝性脑病发生的可能性。
Objective To investigate the relationship between portal vein diameter and Child-Pugh classification of liver function and hepatic encephalopathy in patients with cirrhosis. Methods One hundred and six patients with cirrhosis were examined by liver color Doppler ultrasonography. The Child-Pugh grading standard was used to classify the liver function. The relationship between the main diameter of the portal vein and Child Pugh classification of liver function and the degree of hepatic encephalopathy were analyzed. Results There was no correlation between the main diameter of portal vein and the Child-Pugh classification of liver function in cirrhotic patients, but the incidence of hepatic encephalopathy was increased with the decrease of liver reserve function (P <0.01). The main diameter of portal vein in cirrhotic patients with hepatic encephalopathy was lower than that without The hepatic encephalopathy was widened (P <0.05), but there was no significant difference in the main trunk diameter of portal vein between patients with different degrees of hepatic encephalopathy (P> 0.05). Conclusions The possibility of hepatic encephalopathy in cirrhotic patients is predicated on the diameter of the main portal vein.
