Minimally invasive vascular interventions for liver tumors are chemotherapy and embolization treatment via hepatic artery infusion. Specifically, the catheter is selected to the tumor blood supply vessel, and the chemotherapeutic drugs and embolic agents are infused through this vessel, so that the drugs not only reach the tumor organ in priority and increase the local drug concentration, but also can block the tumor blood supply to achieve the purpose of “starving” tumor. Since liver is the metabolizing organ of most drugs, after infusing chemotherapy drugs through hepatic artery, most of the drugs are metabolized in liver first, so that the drugs reaching other parts of the body are obviously reduced, thus reducing the side effects of chemotherapy. Because of the above advantages, minimally invasive vascular intervention is recognized as the treatment of choice for liver tumors that cannot be surgically removed. Advantages of vascular interventional therapy: 1. Less trauma, faster recovery; 2. Significant efficacy; 3. Fewer side effects of treatment.
