Interventional medicine can be divided into: diagnostic interventions; therapeutic interventions according to the purpose. According to the operation route, it can be divided into: endovascular intervention; extravascular intervention. According to the anatomical site, it can be divided into: neurointervention; cardiovascular intervention; non-vascular intervention. According to the instrumentation used, it can be divided into: radiological intervention, ultrasound intervention, magnetic resonance intervention, and lumpectomy intervention. Interventional techniques have been widely used in clinical practice. The diseases involved include all systems of the body. The following diseases can be treated very well through interventional therapy, and some of them can be completely cured. Neurological system brain infarction, aneurysm, intracranial artery stenosis resulting in insufficient intracranial blood supply, arteriovenous malformation, interventional treatment of intracranial tumors, Parkinson’s, etc. Head and neck diseases different carotid artery stenosis, interventional treatment of hyperthyroidism, interventional treatment of benign and malignant tumors of the head and neck, arteriovenous malformation, lacrimation, etc. Respiratory system diseases stent treatment of tracheal stenosis, pulmonary arteriovenous leak, pulmonary arteriovenous malformation, interventional treatment of lung cancer, interventional treatment of bronchial arteriovenous malformation, large coughing blood. Digestive system diseases stent treatment for esophageal stenosis, intestinal stenosis, stem cell treatment for liver failure, interventional treatment for cirrhosis of the liver with vomiting blood, interventional treatment for hypersplenism, interventional perfusion plus embolization treatment for blood in the stool caused by vascular malformation of the digestive tract, Buka’s syndrome, gastric cancer, esophageal cancer, liver cancer, intestinal cancer, hepatic hemangioma, etc. Orthopedic diseases: interventional treatment of lumbar disc herniation, cervical disc herniation, interventional treatment of aseptic necrosis of femoral head, interventional treatment of compression fracture, embolization treatment of bone malignant tumor, etc. Obstetrical and gynecological diseases: interventional treatment of ectopic pregnancy, postpartum hemorrhage, uterine fibroids, adenomyosis, etc., interventional treatment of tubal incompetence, etc. Interventional treatment of vascular diseases such as pulselessness, thrombo-occlusive vasculitis, arterial thrombosis, venous thrombosis, varicose veins, atherosclerotic occlusive disease, diabetic foot, renal hypertension due to renal artery stenosis, subclavian artery steal syndrome, vasculitis, etc. Interventional medicine has become an important part of modern medicine, and it is believed that with the development of modern technology, interventional technology will relieve the pain of more patients.
