1.Angiographic diagnosis of all parts of the body, including coronary angiography and cerebral angiography, is the gold standard for diagnosing vascular lesions. 2.Localized perforation biopsy of masses of unknown nature in various parts of the body to determine their benign or malignant nature, avoiding blindness in treatment. 3.Interventional therapy for various malignant tumors (such as primary liver cancer, metastatic liver cancer, lung cancer, cholangiocarcinoma, pancreatic cancer, intestinal cancer, renal cancer, breast cancer, bladder cancer, esophageal cancer, gastric cancer, uterine cervix cancer, endometrial cancer, ovarian cancer, cerebral gliomas, bone tumors, etc.). Including transcatheter tumor blood supply artery chemotherapeutic drug perfusion, tumor blood supply artery embolization to block tumor nutrition and other methods. 4.Many kinds of benign tumors: hepatic hemangioma, uterine fibroid, meningioma, thyroid adenoma, etc. Most of them can be cured at one time. 5, vascular diseases in all parts of the body: arterial stenosis, vascular occlusion, aneurysm, deep vein thrombosis, vascular malformation caused by coronary heart disease, renal hypertension, cerebral hypoperfusion, smoky disease, pulselessness, aortitis, Bugatti’s syndrome, atherosclerosis occlusion of the lower extremities, lower extremity edema and other interventional treatments. Such as balloon dilatation of vascular stenosis, stent placement, catheter thrombolysis, filter implantation and vascular embolization. 6.Treatment of thrombotic diseases: cerebral thrombosis, cerebral embolism, central retinal artery (static) embolism, acute pulmonary infarction, limb arterial and venous embolism or thrombosis, mesenteric artery embolism and so on. 7.Non vascular interventional treatment of luminal stenosis and obstruction, such as esophageal stent implantation for esophageal stenosis and dysphagia due to esophageal cancer, gastric fundus cardia cancer, pancreatic achalasia; biliary drainage and stenting for obstructive jaundice due to cholangiocarcinoma, pancreatic cancer, etc; tracheal stenting for respiratory difficulties due to lung cancer and mediastinal tumors; as well as treatment for stenosis of the duodenum, rectum, and ureter. 8.Suction sclerotherapy for various cysts: such as liver cyst, kidney cyst, spleen cyst, ovarian cyst, etc. The treatment is thorough, avoids open surgery and is not easy to recur. 9.Transjugular intrahepatic portal vein shunt (TIPS), percutaneous puncture portal vein esophageal fundus varices vein embolization, etc. are used for the treatment of cirrhosis portal hypertension, esophageal fundus varices, upper gastrointestinal hemorrhage, intractable ascites and so on. 10, acute bleeding disorders (digestive bleeding, respiratory hemoptysis, organ rupture, vascular injury, pelvic organs such as uterus, bladder bleeding, etc.) diagnosis and interventional therapy. Common diseases include bronchiectasis, tuberculosis, nosebleed, gastroduodenal ulcer, tumor, gastrointestinal vascular malformation, traumatic rupture of liver, spleen and kidney, bladder cancer, uterine hemorrhage and so on. 11.Selective tubal imaging and interventional recanalization for tubal infertility. 12.Interventional treatment of hyperfunctioning diseases, including hyperthyroidism, hypersplenism, etc. 13.Pyramidoplasty(PVP) to treat pain and cone instability caused by vertebral metastasis, osteoporosis and vertebral hemangioma. 14.Spermatic vein embolization to treat pain, infertility and sexual dysfunction caused by varicocele. 15, Percutaneous lumbar disc cutting and aspiration or collagenase dissolution for lumbar disc herniation. 16.Interventional therapy for aseptic necrosis of femoral head. 17.Inflammatory lesions: liver abscess, abdominal and pelvic abscess. 18.Ectopic pregnancy intervention.
