自从日本学者报道了病灶内注射无水酒精治疗小肝癌,取得良好效果后,临床上逐步广泛地应用此法治疗肝癌。酒精与细胞原生质相遇,能使蛋白质脱水沉淀和凝固。我院通过动物实验和尸解观察,发现肝癌及正常肝组织经无水酒精注射后,局部呈灰白色或灰黄色,组织呈无菌性坏死、纤维硬结,结缔组织增生,边界清楚、有的肿块周边形成包膜,其内无正常肝细胞及肿瘸细胞。有人在注射前、后进行肝动脉造影,发 Since Japanese scholars reported the intralesional injection of absolute alcohol for the treatment of small hepatocellular carcinoma and achieved good results, this method has been widely used clinically to treat liver cancer. Alcohol meets cell protoplasm and dehydrates and coagulates proteins. In our hospital through animal experiments and autopsy observation, found that liver cancer and normal liver tissue after alcohol injection, the part was gray or grayish yellow, the organization was aseptic necrosis, fiber induration, connective tissue hyperplasia, clear boundaries, some lump Peripheral formation of the capsule, there is no normal liver cells and swollen cells. Hepatic arteriography was performed before and after injection.
