应用多普勒超声评价了１０３例慢性病毒性肝炎患者及３４例正常人门静脉血流动力学改变与肝组织炎症分级的关系。结果显示：门静脉主干直径（ＰＤ）及淤血指数（ＣＩ）与炎症坏死程度（Ｇ）呈显著正相关关系；门静脉最大流速（ＰＶｘ）及平均流速（ＰＶｍ）则呈显著负相关关系；而门静脉血流量（ＰＢＦ）无明显相关关系。作者认为：ＰＤ、ＰＶｘ、ＰＶｍ及ＣＩ可用于评价慢性病毒性肝炎炎症坏死活动度，特别是在鉴别中重度（Ｇ３－４）与轻度（Ｇ１－２）炎症、正常与Ｇ２级病变等方面有较重要意义 The relationship between portal hemodynamic changes in 103 patients with chronic viral hepatitis and 34 healthy controls and the grade of inflammation in liver tissue was evaluated by Doppler echocardiography. The results showed that there was a significant positive correlation between the main diameter of the portal vein (PD) and the congestion index (CI) and the degree of inflammation and necrosis (G). There was a significant negative correlation between the PVx and PVm of the portal vein. Traffic (PBF) no significant correlation. The authors suggest that PD, PVx, PVm, and CI can be used to assess the degree of inflammatory necrosis in patients with chronic viral hepatitis, especially in the identification of moderate to severe (G3-4) and mild (Gl-2) inflammation, More important
