Interventional treatment is an emerging treatment method between surgical and medical treatment, including intravascular and non-vascular interventions. After more than 30 years of development, it is now known as one of the three pillar disciplines along with surgery and internal medicine. Simply put, interventional therapy is the least invasive treatment method that involves making tiny channels of a few millimeters in diameter in blood vessels or skin, or treating the lesion locally under the guidance of imaging equipment (angiography, fluoroscopy, CT, MR, B ultrasound) without opening the lesion to expose it. Interventional treatment is characterized by small trauma, simplicity, safety, effectiveness, less complications and significantly shorter hospital stay. 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 dosage of the drug and reduce the side effects of the drug. 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 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.).
