现行经皮穿刺治疗肝脏肿瘤的方法主要有两类:一、病灶内注射:①经皮穿刺乙醇注射(PEIT),已广泛应用。其优点是操作方便,价廉、并发症少、无需住院,其生存期与手术相似;②经皮穿刺乙酸注射,具有用量少,坏死严重的优点;③热盐水注射的死亡率和合并症的发生较PEIT 低。后两种方法仅见少数报道,具有替代乙醇的潜力,对不可切除的肝细胞癌选择经皮穿刺肿瘤注射是有效的非手术治疗方法,既可
The current methods of percutaneous puncture for liver cancer are mainly two types: First, intralesional injection: 1 Percutaneous ethanol injection (PEIT) has been widely used. Its advantages are convenient operation, low cost, less complications, no need of hospitalization, and its survival period is similar to that of surgery; 2 Percutaneous injection of acetic acid has the advantages of less dosage and severe necrosis; 3 Mortality and complications of hot saline injection The occurrence of PEIT is lower. The latter two methods have seen only a few reports and have the potential to replace ethanol. The selection of unresectable hepatocellular carcinoma is an effective non-surgical treatment for percutaneous tumor injection.
