Interventional radiology is a minimally invasive discipline based on diagnostic imaging, using puncture needles, catheters and other interventional devices to treat diseases or collect histological, bacteriological and physiological and biochemical data for diagnosis under the guidance of medical imaging equipment. It is an emerging and marginal discipline with the characteristics of minimally invasive, convenient, fast-acting and effective, and is now widely used in clinical practice. Interventional radiology is a discipline that integrates diagnosis and treatment, covering almost all parts and organs of the body. In the cardiovascular system whether it is the coronary arteries, or other parts of the vascular stenosis or occlusion, can be treated using interventional radiology molding procedures. Whether it is a vascular malformation in the nervous system or altered hemodynamics in other areas, it can be treated by embolization. Tumors represented by hepatocellular carcinoma have been treated using perfusion (embolization), and although the lesions cannot be completely eradicated, significant efficacy has been obtained in terms of improving the quality and prolonging the survival time. The treatment of abscess and cyst-like lesions is even easier and faster, and good therapeutic results can be obtained. Through the combination of multiple interventional radiology methods, the so-called integrated interventional radiology, we can independently provide effective treatment for some complex pathologies and diseases that are difficult to achieve good results with medical and surgical treatment, such as liver cirrhosis and intrahepatic bile duct cell carcinoma. Scope of treatment: 1.Interventional recanalization of esophagus, gastrointestinal tract, large intestine, tracheal stenosis and biliary stenosis (metal stent placement, balloon dilation); 2.Interventional evacuation of intestinal obstruction; 3.X-ray guided percutaneous gastrostomy; 4.Tranasal small intestine nutrient tube placement; 5.Interventional chemotherapy and embolization of malignant tumors; 6.Interventional drainage of obstructive jaundice (percutaneous hepatic puncture bile drainage); 7.Percutaneous nephrostomy of hydronephrosis 7. percutaneous nephrostomy and drainage of hydronephrosis (percutaneous nephrostomy and drainage); 8. minimally invasive interventional treatment of cysts, abscesses and effusions; 9. arterial embolization of symptomatic uterine fibroids and preoperative embolization of scar pregnancy; 10. embolization of arterial bleeding for various reasons; 11. partial splenic artery embolization for hypersplenism; 12. percutaneous percutaneous injection of drugs for extinction of hepatocellular carcinoma; 13. Biopsy.
