Interventional therapy is characterized by small trauma, simplicity, safety, effectiveness, few complications and significantly shortened hospitalization time. For diseases requiring medical treatment, the advantages of interventional therapy compared with medical treatment are: the drug can act directly on the lesion, which can not only greatly increase the concentration of the drug at the lesion site, but also greatly reduce the amount of drugs and reduce drug side effects. Second, for diseases requiring surgical treatment, the advantages of interventional therapy compared with surgical treatment are: 1, it does not require an incision to expose the lesion, generally only a few millimeters of skin incision, you can complete the treatment, epidermal damage is small, beautiful appearance. 2, most patients only need local anesthesia instead of general anesthesia, thus reducing the risk of anesthesia. 3.Little damage, fast recovery, satisfactory effect, and little impact on normal body organs. 4. For malignant tumors that are difficult to treat, interventional therapy can confine the drugs to the lesion as much as possible, while reducing the side effects on the body and other organs. Some tumors are equivalent to surgical resection after interventional treatment. Because of these many advantages, many interventional treatment methods have become one of the most important treatment methods for some diseases (such as: liver cirrhosis, liver cancer, lung cancer, lumbar disc herniation, aneurysm, vascular malformation, uterine fibroids, etc.).
