移植后肝脏活检遇到的主要问题是区别复发性丙型肝炎和移植排斥反应的形态学改变。众所周知,虽然丙型肝炎患者的肝脏活检有胆管损害,但诸如内皮炎、肝门区嗜酸性粒细胞浸润和中央周围纤维化等其他类似于移植排斥反应的形态学特征尚未被公认。为了确定二者之间有多少类似的形态 The main problem encountered after liver transplant biopsy is the difference between the morphological changes of recurrent hepatitis C and transplant rejection. It is well-known that other morphological features similar to transplant rejection such as endothelitis, eosinophilic edema and central periventricular fibrosis are not well recognized, although liver biopsies from patients with hepatitis C have biliary damage. In order to determine how much similar between the two forms
