Interventional tumor treatment mainly adopts intra-arterial perfusion chemotherapy via tumor vessels, tumor vascular embolization therapy, tumor local puncture chemical and physical ablation therapy, gene interventional therapy and other techniques. Arterial infusion chemotherapy for malignant tumors is mainly based on the characteristics of tumor blood supply on the basis of angiography, and the catheter is inserted into the tumor supply vessels to inject tumor-sensitive chemotherapeutic drugs. The local infusion of chemotherapeutic drugs can increase the local drug concentration of tumor by 6~20 times compared with systemic chemotherapy through intravenous, thus improving the effect of chemotherapy. Interventional embolization therapy for malignant tumors is aimed at high blood supply tumor lesions, injecting vascular embolic agent through catheter to occlude tumor blood supply arteries, so as to inhibit tumor growth, and even lead to tumor cell apoptosis and tumor tissue necrosis. Chemical ablation therapy of percutaneous puncture malignant tumor is to inject chemical substances directly into the tumor body to achieve tumor necrosis through direct contact damage of chemical substances to tumor cells and tissues and blood vessels. Physical ablation therapy of percutaneous puncture malignant tumor is to deliver microwave, radiofrequency electromagnetic wave, laser and other energy through puncture needle, resulting in local tissue heating to the extent that it can inactivate tumor cells, coagulate protein and cause apoptosis and necrosis of tumor cells. Tissue cell apoptosis and necrosis.
