What is interventional therapy? I believe many doctors do not know what it is, and many patients do not know what it is. Usually, when we talk about interventional treatment, we mean interventional radiology. Interventional radiology is an emerging and marginal discipline based on diagnostic imaging, using puncture needles, catheters and other interventional devices under the guidance of medical imaging diagnostic equipment to treat diseases or to collect histological, bacteriological and physiological and biochemical data for diagnosis and treatment. Since 1929, when German surgeon Werner Forssmann performed the first cardiac catheterization on himself, both interventional-oriented equipment, devices, drugs and techniques have undergone radical changes. In 1990, the Ministry of Health of China decided to change the radiology department for interventional radiology into a clinical department; in 1997, the State Science Committee and the Ministry of Health jointly listed the interventional radiology project as a “Ninth Five-Year Plan” research project, which laid the foundation for the vigorous development of interventional radiology in the 21st century. In 1997, the State Science Committee and the Ministry of Health jointly listed interventional radiology as a “Ninth Five-Year Plan” project, which laid a good foundation for the vigorous development of interventional radiology in the 21st century. Interventional radiology is a discipline that integrates diagnosis and treatment, covering almost all parts and organs of the body. In the cardiovascular system, whether it is the coronary arteries, or other parts of the vascular stenosis or occlusion, can be treated using interventional radiology molding procedures. Whether it is a vascular malformation in the nervous system or altered hemodynamics in other areas, it can be treated by embolization. Tumors represented by hepatocellular carcinoma are treated using perfusion (embolization), and although the lesion cannot be completely eradicated, significant efficacy has been obtained in terms of improving the quality and prolonging the survival time. The treatment of abscess and cyst-like lesions is even easier and faster, and good therapeutic results can be obtained. The combination of multiple interventional radiology methods, the so-called comprehensive interventional radiology, can independently provide effective treatment for some complex pathologies that are difficult to achieve good results with medical and surgical treatment, such as liver cirrhosis and intrahepatic bile duct cell carcinoma. At present, interventional radiology has become one of the three major disciplines alongside with internal medicine and surgery.
