Interventional treatment of hepatocellular carcinoma generally refers to minimally invasive surgery for hepatocellular carcinoma, which is a large category of treatment including multiple methods, commonly used methods include tumor ablation, regional chemotherapy via hepatic artery or portal vein, regional embolization surgery, etc. Postoperative reactions vary among different surgical methods: tumor ablation generally kills some tissues directly through microwave, radiofrequency, freezing, anhydrous alcohol injection, etc., due to limited scope The trauma is small and does not involve specific drugs, generally no systemic reactions will occur, a few patients will have inflammatory reactions such as fever and pain due to necrotic tissue. Regional embolization via hepatic artery or portal vein is mainly done by artificially blocking the blood vessels supplying the cancerous tissues to induce necrosis of the tumor tissues, if the scope of blockage is too large, ischemic necrosis of hepatocytes will occur and liver function will be lost. Regional chemotherapy via hepatic artery or portal vein, this type of procedure is a treatment method by injecting chemotherapeutic drugs to specific locations precisely. Compared with systemic chemotherapy, the positioning is more precise, the dose is smaller, and the reaction is also smaller. Postoperative reactions are also similar to chemotherapy, such as weakness, fever, and blood cell drop, but the reaction is much milder compared with systemic chemotherapy. Therefore, interventional treatment for hepatocellular carcinoma is a type of treatment including multiple methods, and the postoperative reactions vary among different surgical methods, but in general, less invasive and less adverse reactions are the common features of such treatment.
