Simply put, it is a minimally invasive endoluminal surgical treatment that uses high-tech equipment with a TV monitor to open a small hole in a certain part of the human body and then use a catheter to penetrate deep into the patient’s internal blood vessels for repairing, expanding, and unblocking. By the clinical interventional therapy as the main axis, the professional discipline of interventional radiology has also been formed. Interventional radiology, also known as interventional therapy, is a rapidly developing discipline in recent years that integrates diagnostic radiology and clinical therapeutics. It is a clinical application of diagnostic radiology equipment (digital subtraction X-ray machine, CT machine, MRI machine and conventional X-ray machine, etc.) under the guidance of a small incision through the introduction of specific devices into the human body for treatment of the diseased area. Interventional medicine adopts “non-surgical, minimally invasive surgical” methods to treat a variety of diseases. In recent decades, interventional medicine has developed rapidly and has become one of the three pillars of clinical medicine, together with internal medicine and surgery.
