Interventional therapy” in the old white surname is actually an emerging discipline – interventional radiology, which is a marginal discipline and cross-discipline combining medical imaging and clinical treatment developed in the 1970s. Due to the rapid advancement of medical imaging equipment and technology, the discipline has been rapidly popularized around the world, and with the development in the past 30 years, it has now become the third largest treatment technology alongside internal medicine and surgery. Previously, medical and surgical interventions for incurable or intractable diseases have opened up new and effective treatment methods. Since it is not like the traditional medical drugs, it is different from the surgical “drastic”, between the two, so it is called interventional radiology. The latest standard concept of interventional radiology is: under the surveillance of medical imaging equipment (X-ray machine, B ultrasound, CT, and even MRI), a minimally invasive technique is used to insert a puncture needle or introduce a catheter or guide wire through the skin or lumen to do aspiration, injection, drainage, fistula, or to shape, perfuse, or embolize official cavities and blood vessels for diagnosis and treatment. From the concept we can analyze: 1, interventional radiology is first of all a medical imaging (diagnostic) technology. 2, interventional radiology is a minimally invasive technology. 3, interventional radiology is a clinical treatment method. 4.Interventional radiology is a marginal and interdisciplinary discipline. Interventional radiology treatment scope (including vascular and non-vascular): 1. Vascular interventions Tumor lesions of all systems: liver cancer, kidney cancer, esophageal cancer, pelvic tumors, bone tumors, metastases, benign hepatic hemangioma, uterine fibroids, etc. Peripheral vascular lesions: arterial and venous stenosis and thrombotic diseases, aneurysms, arteriovenous fistulas, etc. For example, renal artery stenosis, Buccal’s syndrome, superior vena cava syndrome, deep vein thrombosis of the lower extremities, embolism and occlusion of the arteries of the extremities, etc. Cardiac and macrovascular diseases: coronary artery stenosis and occlusion (coronary artery disease), pulmonary valve and aortic valve stenosis, precordial disease (patent ductus arteriosus, atrial septal defect, ventricular septal defect), coarctation aneurysm, etc. Cerebrovascular diseases: cerebral thrombosis, cerebral aneurysm, carotid artery, vertebral artery and other intracranial vascular stenosis, cerebrovascular malformation, carotid cavernous sinus fistula, etc. Hemorrhagic diseases: Gastrointestinal bleeding (vomiting blood, fecal blood), hemoptysis caused by pulmonary lesions, hemorrhage caused by obstetrical and gynecological diseases, persistent rhinorrhea, hemorrhage of liver, kidney, spleen and other organs caused by trauma and other causes, etc. Other pathologies: hypersplenism, ectopic pregnancy, portal hypertension, acute pancreatitis, etc. 2. Non-vascular interventions: biopsy of various organs throughout the body: biopsy of pulmonary and hepatic occlusions, etc. Stenosis, occlusion and stenting of benign and malignant lumen: esophageal stenosis, tracheal stenosis, esophageal-tracheal fistula, biliary stenosis and obstruction, ureteral obstruction, ureteral recanalization and family planning ureteral ligation, etc. Aspiration and sclerosis of cysts and drainage of abscesses in various organs of the body: such as aspiration and sclerosis of cysts in liver, kidney and adnexa, drainage of liver abscesses, etc. Ion implantation of malignant tumors, intervertebral disc aspiration and vertebroplasty Interventional treatment is preferred by more and more patients for its small trauma, low cost (short hospital stay of 3-5 days, some patients do not even need to be hospitalized), high efficacy and fast results. New interventional treatment methods are emerging, and related reports are in the press, so I believe the future of interventional treatment is bright.
