Intervention can be done for liver cancer. Commonly used interventional methods for liver cancer contain: vascular interventional therapy (transcatheter hepatic artery perfusion chemotherapy, transportal vein intervention, etc.), and non-vascular interventional therapy (percutaneous ablation, ultrasound ablation, radioactive particle implantation, etc.). The indications and contraindications for different programs are different. 1. Indications for transhepatic artery cannula embolization chemotherapy: ① patients who are unable or unwilling to undergo surgical resection; ② large size of hepatocellular carcinoma with great difficulty in surgical resection; ③ adjuvant treatment after hepatocellular carcinoma surgery; ④ palliative treatment or treatment of emergencies such as rupture and bleeding of hepatocellular carcinoma and hepatic arteriovenous fistula. Contraindications are: ① severe hepatic insufficiency, Child-Pugh grade C; ② obstruction of portal vein due to cancer thrombus or other reasons; ③ tumor volume greater than 70% of total liver volume; ④ severe platelet and leukocyte reduction. 2. Radiofrequency ablation is suitable for hepatocellular carcinoma that is not suitable for surgical resection, the number of lesions is less than 3, the maximum diameter of the tumor is less than 5cm, and the effect is best within 3cm; Contraindications: severe hepatic and renal failure (Child-Pugh grade C), coagulation disorders or long-term use of aspirin/warfarin, etc., severe hepatic encephalopathy, large amount of refractory ascites, acute or active infections, tumors that are too close to the porta hepatis/choledochal ducts/right and left hepatic ducts/gallbladder (<0.5cm), etc. It is recommended to go to the regular hospital to evaluate the condition, follow the doctor’s instructions to cooperate with the treatment, and choose the appropriate program to avoid delaying the condition.
