The basic techniques of interventional radiology are puncture techniques, selective catheter techniques, and commonly used treatment modalities include selective angiography, transcatheter intravascular infusion (IAI), transcatheter intra-arterial embolization (TAE), percutaneous transluminal balloon angioplasty (PTA), percutaneous transluminal stenting (Stenting), microcatheter techniques, inferior vena cava strainer placement, cardiovascular foreign body removal The techniques include: intravascular thrombectomy, puncture biopsy, puncture drainage, etc. Various interventional radiology techniques have been widely used in clinical practice, and the diseases involved include all systems of the body, some of which can achieve very good results through interventional treatment, and some diseases can be completely cured. Neurological system: acute cerebral infarction, aneurysm, intracranial artery stenosis resulting in insufficient intracranial blood supply, arteriovenous malformation, intracranial tumor, etc. Head and neck diseases: carotid artery stenosis, hyperthyroidism, benign and malignant tumors of the head and neck, arteriovenous malformations, lacrimation, local hemorrhage, etc. Respiratory system diseases: tracheal stenosis, pulmonary arteriovenous leak, pulmonary arteriovenous malformation, lung cancer, bronchial arteriovenous malformation, major coughing up blood, etc. Digestive system diseases: esophageal stenosis, esophageal bronchial leak, intestinal stenosis, stem cell therapy for liver failure, hematemesis with cirrhosis, hypersplenism, blood in the stool due to vascular malformation of the digestive tract, Bukka’s syndrome, stomach cancer, esophageal cancer, liver cancer, intestinal cancer, hepatic hemangioma, etc. Orthopedic diseases: lumbar disc herniation, interventional treatment of cervical disc herniation, aseptic necrosis of femoral head,, vertebral compression fracture, malignant tumor of bone and joint soft tissue, vascular malformation, traumatic bleeding, vasculitis ischemia, etc. Obstetrical and gynecological diseases: ectopic pregnancy, postpartum hemorrhage, uterine fibroids, uterine adenomyosis, tubal incompetence, etc. Vascular diseases: pulseless evidence, 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.
