附录3 肝纤维化分期半定量评估系统 依据对肝纤维化的分布、纤维化的形式及数量改变参数进行量化评估,组织学分期按F0-F4区分。F0和F1反映轻度纤维化;F2和F3为中度纤维化;F4为重度纤维化。 几种肝纤维化分期半定量评估系统
注:PF为汇管区纤维化;P-P汇管-汇管桥接纤维化;P-C为汇管-中央桥接纤维化 以F0-1表示无明显纤维化;而以纤维隔或桥接纤维化的出现,即Scheuer和METAVIR≥F2或Ishak≥F3定为临床明显纤维化(CSF),因此,评估F2与F3之间的纤维化进展较F1与F2之间的进展显得更为重要。 六、参考文献 1.中华医学会肝病学分会和中华医学会感染病学分会.慢性乙型肝炎防治指南(2015年更新版).临床肝胆病杂志,2015,12:1941—1959. 2.WHO.
