Interventionaltreatment is an emerging treatment method between surgical and medical treatment, including intravascular intervention and non-vascular intervention. After more than 30 years of development, it is now known as one of the three pillar disciplines along with surgery and internal medicine. In simple terms, interventional treatment is the least invasive treatment method to treat the lesion locally under the guidance of imaging equipment (angiography, fluoroscopy, CT, MR, B ultrasound) without opening the lesion and exposing it by making a tiny channel of a few millimeters in diameter in the blood vessel or skin, or through the original pipeline of the human body. 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.Small damage, fast recovery, satisfactory results, and little impact on normal body organs. 4. For malignant tumors that are difficult to treat at present, 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 advantages, many interventional methods have become one of the most important treatment methods for some diseases (such as: pediatric giant hemangioma, venous malformation, lymphatic duct malformation, arteriovenous fistula, hepatoblastoma and retinoblastoma, congenital esophageal stenosis, etc.).
