What does interventional therapy mean? As we know, surgical treatment is done after surgical exposure; medical treatment is done by taking medication; while interventional treatment is not like the kind of exposed, open surgery that is completely opened, and at the same time, it is not a kind of surgery that relies on medication to treat, it is between the two, so American doctors named it intervention (the meaning of interventional intervention), and it is called interventionalist treatment. Simply put, it is a minimally invasive endoluminal surgical treatment that uses high-tech equipment with a television monitor to make a small hole in a part of the body and then uses a catheter to penetrate deep into the patient’s body to repair, expand, and unblock the blood vessels. With clinical intervention as the main axis, the specialized discipline of interventional radiology was soon formed. The term “interventional radiology” was first coined by the American radiologist Margulis, who was keenly aware of the development of a new specialty in the field of radiology and wrote a review entitled “Interventional Radiology: A New Specialty”, published in March 1967 in the internationally renowned academic journal AJR. In this review, he defined interventional radiology as a diagnostic and therapeutic technique performed under fluoroscopic guidance. In this review, he defines interventional radiology as the practice of fluoroscopically guided diagnosis and treatment. However, the term “Interventional Radiology” became widely recognized by the academic community in 1976, when Wallace systematically described the concept of interventional radiology in the journal Cancer under the title “Interventional Radiology”. The term “Interventional Radiology” was officially recognized by the international academic community only after Wallace systematically described the concept of Interventional Radiology in the journal Cancer in 1976 and made a presentation at the first European Society of Radiology Interventional Radiology meeting held in Portugal in 1979. The name “Interventional Radiology” has been translated by domestic scholars in various ways, such as “surgical radiology”, “interventional radiology “therapeutic radiology”, “invasive radiology”, etc., and also “catheterization”, but now generally willing to accept The name “interventional radiology” is generally accepted now. China’s interventional radiologists have also made a specific definition of this name. Interventional radiology is based on diagnostic imaging, under the guidance of medical imaging diagnostic equipment (DSA, US, CT, MRI, etc.), to make independent diagnosis and treatment of disease. It is minimally invasive intracavitary surgical treatment in terms of clinical treatment attributes. Interventional treatment 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. Simply put, interventional treatment is the least invasive treatment method that involves making tiny channels of a few millimeters in diameter in blood vessels or skin, or through the body’s original pipelines, under the guidance of imaging equipment (angiography, fluoroscopy, CT, MR, B ultrasound) to treat the lesion locally without opening an incision to expose the lesion.
