Interventional treatment of liver cancer is a method of inserting special puncture needles and catheters into the tumor area of the liver for diagnosis and treatment under the guidance of X-ray TV, CT and B-ultrasound. It has gained more clinical experience and therefore is developing rapidly, and now it has become an effective means to treat liver cancer. The following patients with hepatocellular carcinoma can be treated with hepatic interventional therapy, which usually refers to hepatic artery embolization chemotherapy, and its main indications: 1. primary or metastatic hepatocellular carcinoma that cannot be removed surgically for various reasons, or small hepatocellular carcinoma that the patient does not want to operate. 2.As a preparation before surgery, interventional therapy can shrink liver cancer, better clarify the number of tumor, make surgery easy to resect and control metastasis, in addition, it can reduce the spread and recurrence of tumor after intervention. 3.Patients whose hepatocellular carcinoma is not completely resected, relapsed after surgery or failed to be treated by other methods. 4.hepatocellular carcinoma lesion rupture and bleeding, play a role of hemostasis. 5.Pain in liver cancer, and control pain through interventional embolization. 6.Blocking arteriovenous fistula of liver cancer. 7.Prophylactic hepatic artery chemoembolization after hepatocellular carcinoma resection, which plays the role of preventing recurrence. 9.Recurrence of hepatocellular carcinoma after liver transplantation. According to the current progress of hepatic artery embolization chemotherapy, combined with our experience, for patients with portal trunk aneurysm embolization and giant hepatocellular carcinoma, we adopt the combination of arterial infusion chemotherapy and embolization chemotherapy with small amount of multiple embolization to take a better clinical efficacy. The important guarantee for the success of interventional therapy is the three components of careful preoperative evaluation, careful intraoperative imaging to determine the usage and dosage of embolic agents, and close postoperative observation and care and supportive treatment. Although hepatocellular carcinoma is currently treated mainly by surgery and intervention, comprehensive treatment is more important, such as postoperative interventional chemotherapy for hepatocellular carcinoma, which can not only detect residual lesions, but also prevent recurrence and metastasis after surgery. Interventional treatment for liver cancer not only can detect residual lesions, but also can prevent recurrence and metastasis after surgery. In addition, interventional therapy combined with targeted therapy, biological immunotherapy, and the combination of multiple interventional therapies, even with traditional Chinese medicine, can further improve the efficacy. In addition, health education and psychological support for liver cancer patients and their families are also indispensable to improve the efficacy.
