Interventional medicine, as the name implies, is a department that performs interventional treatments. It is an emerging and rapidly developing discipline. Nowadays, compared with medical, surgical and clinical departments, interventional medicine is characterized as a department that performs diagnosis and treatment of local lesions under the guidance of imaging equipment by making tiny channels of a few millimeters in diameter on the skin or through the body’s original cavities without opening the lesions to expose them. According to its technology, it can be divided into vascular interventional technology and non-vascular interventional technology. According to the scope of treatment, it can be further divided into tumor intervention, non-tumor intervention, neurointervention, cardiovascular intervention, gynecological intervention, skeletal muscle intervention, etc. Since it is different from surgical open surgery and not just medication in internal medicine, it has a wide range of clinical applications and can treat a variety of diseases that cannot be treated in internal medicine. It is more non-invasive compared to surgical open surgery and has taken an important position in the field of disease treatment. And with the advantages of accuracy, safety, high efficiency, wide indications and few complications, it has become the preferred treatment method for many diseases.
