Interventional treatment of liver cancer: Interventional treatment of liver cancer is a method to diagnose and treat liver cancer by inserting special puncture needles and catheters into the tumor area of the liver 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 of treating liver cancer. Interventional treatment for liver cancer is feasible for the following patients: (1) primary or metastatic liver cancer that is considered inoperable for various reasons, or small liver cancer that the patient does not want to operate. (2) As a preparation before surgery, liver cancer can be shrunk through interventional treatment, which makes surgery easy to remove, and in addition, tumor spread and recurrence can be reduced after intervention. (3) Patients with incomplete resection of hepatocellular carcinoma, postoperative recurrence or failure of other methods of treatment. (4) The liver cancer lesion does not rupture and bleed. (5) No serious impairment of liver or kidney function. (6) Patients without severe jaundice and ascites. (7) Patients with good general condition and no serious bleeding disease. Due to the improvement of science and technology, the catheters, guidewires and puncture needles used for intervention have been greatly improved, coupled with the more research and understanding of hepatocellular carcinoma, there are more treatment methods. Such as hepatic artery cannulation chemotherapy, thermal chemotherapy, hepatic artery cannulation embolization, thermal embolization, percutaneous puncture anhydrous alcohol injection, percutaneous puncture iodine oil plus chemotherapy drug injection, isotope guided therapy for liver cancer, etc. The effectiveness of interventional therapy is determined by the characteristics of blood supply to liver cancer. Normally, the liver is supplied with blood by hepatic artery and portal vein, of which portal vein supply accounts for 75% to 80% and hepatic artery supply accounts for 20% to 25%. The blood supply of hepatocellular carcinoma is exactly the opposite, with more than 90% to 95% of the blood supply from hepatic artery and very little blood supply from portal vein. This brings convenience to the treatment. Through hepatic artery cannulation, drugs can directly enter liver cancer tissues to increase the local drug concentration and kill cancer cells. In addition, some embolic substances such as iodine oil and gelatin sponge are applied to embolize the blood supply artery of liver cancer to cut off its nutritional effect, and the tumor tissue will be necrosed, thus achieving the purpose of treatment. The observation and care of patients after intervention is an important part. After the operation, the lower limb of the patient’s punctured side should be braked for 24 hours, and the patient can be fasted for 6 to 12 hours for observation. Due to chemoembolism, patients may have nausea, vomiting, abdominal pain, fever, etc., which should be treated symptomatically in time and can be improved after 1 week. Postoperatively, patients should review liver function, kidney function and blood routine, and pay attention to the changes of each index, and actively deal with the problems when they are found. Although liver cancer is currently treated mainly by surgery and intervention, comprehensive treatment is more important, such as postoperative interventional therapy for liver cancer, 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 radiotherapy, X-knife, γ-knife, Hepatome, computerized positioning multi-electrode radiofrequency, etc. also play a great role in the treatment of liver cancer. Interventional therapy with heat therapy, electrochemical therapy and isotope guided therapy for liver cancer are also under research. The efficacy of interventional therapy plus immunotherapy and traditional Chinese medicine for liver cancer is also being affirmed. In conclusion, hepatocellular carcinoma is a comprehensive treatment based on surgery and intervention. Therefore, it is crucial for patients suffering from liver cancer to build up confidence and choose professional treatment methods and treatment institutions.
