Interventional therapy has a wide scope of application, it can play not only a therapeutic role but also a good diagnostic role. It is mainly used in the following cases: large number of tumors (more than 3); wide distribution (diffuse distribution in the left and right lobes of the liver); large tumors (more than 8 cm in diameter); tumors close to or invading intrahepatic vessels; other cases that are not suitable for surgical resection. Of course, the prerequisite for interventional treatment is that the patient’s general condition can tolerate the intervention.
