为探讨病毒性肝炎患者肝动脉血流变化及其临床意义，采用彩色多普勒超声显像仪，对２３例急性肝炎（ＡＨ）、２３例慢性迁延性病毒性肝炎（ＣＰＨ）、２２例慢性活动性病毒性肝炎（ＣＡＨ）和１９例肝炎后肝硬化（ＬＣ）患者的肝动脉血流的最高峰流速（ＰＳ）、血流阻抗指数（ＲＩ）、平均动脉流速（ＴＡＶ）３项指标进行了检测及研究。结果表明，ＬＣ组患者肝动脉的ＰＳ值和ＴＡＶ值均显著低于ＡＨ组，且ＰＳ的降低与肝炎病变程度呈显著负相关。提示，在病毒性肝炎时，患者的肝动脉将会出现不同程度的供血障碍。因此，在慢性肝炎及肝硬化的治疗中，应注意扩张肝动脉，改善肝血供，保证肝脏的氧供给，方有利于肝脏病变的恢复。
To investigate the changes of hepatic artery blood flow in patients with viral hepatitis and its clinical significance, color Doppler echocardiography was used to evaluate the clinical features of 23 patients with acute hepatitis (AH), 23 chronic persistent viral hepatitis (CPH), 22 chronic (PS), RI, and TAV in 19 patients with active viral hepatitis (CAH) and 19 patients with posthepatitic cirrhosis (LC) The detection and research. The results showed that the hepatic artery PS value and TAV value of LC group were significantly lower than AH group, and the reduction of PS was significantly and negatively correlated with the severity of hepatitis. Tip, in viral hepatitis, the patient’s hepatic artery will appear to varying degrees of blood supply disorders. Therefore, in the treatment of chronic hepatitis and cirrhosis, should pay attention to the expansion of the hepatic artery, improve blood supply to the liver to ensure that the oxygen supply to the liver, in favor of the recovery of liver disease.
