Hepatic interventions are fully known as hepatocellular interventions, including radiofrequency, microwave, and hepatotomy interventions in the liver. It is to kill the tumor with the help of imaging equipment by using a catheter through the femoral-abdominal artery to inject chemotherapy drugs as well as embolic agents into the abdominal aorta, then to the hepatic artery, and finally to the artery where the tumor is located. The basic principle of interventional therapy is based on the fact that our normal liver needs three blood vessels for supply, of which the portal vein accounts for 70% to 75% and the hepatic artery accounts for 20% to 25%. For tumor patients, their blood supply is mainly provided by hepatic artery, which accounts for more than 90% to 95%. If we embolize the hepatic artery of the tumor, the impact on our liver is relatively small, which is the basis for tumor embolization.
Interventional therapy has the following advantages: first, it is minimally invasive and less invasive; second, it is more accurately localized and more effective; third, the drug concentration in liver tissue is 100 to 400 times higher than that in other tissues during interventional therapy, and cancer tissue is 2 to 5 times higher than that in liver tissue; fourth, it can be done repeatedly; fifth, it has fewer side effects and fewer complications; and sixth, it can be used in combination with multiple techniques and is simple and easy to perform. It is the first treatment for patients with liver cancer who are inoperable or unwilling to undergo surgery.
