What diseases can be treated by intervention? 1.Angiography diagnosis of various parts of the body, including coronary angiography and cerebral angiography, is the gold standard for the diagnosis of vascular lesions. 2.Localized puncture biopsy of masses of unknown nature in various parts of the body to determine their benignity and malignancy, avoiding blindness in treatment. 3.Interventional treatment of various malignant tumors (such as primary liver cancer, metastatic liver cancer, lung cancer, bile duct cancer, pancreatic cancer, intestinal cancer, kidney cancer, breast cancer, bladder cancer, esophageal cancer, stomach cancer, cervical cancer, endometrial cancer, ovarian cancer, brain glioma, bone tumors, etc.). Including transcatheter tumor blood supply artery chemotherapy drug infusion, tumor blood supply artery embolization blocking tumor nutrition and other methods. 4.Many benign tumors: hepatic hemangioma, uterine leiomyoma, meningioma, thyroid adenoma, etc. can be cured at one time. 5.Vascular diseases in various parts of the body: arteriovenous stenosis, vascular occlusion, aneurysm, deep vein thrombosis, vascular malformation caused by coronary heart disease, renal hypertension, cerebral hypertension, smog, pulselessness, aortitis, Bu-plus syndrome, lower limb arteriosclerosis occlusion, lower limb edema, etc. Interventional treatment. Such as balloon dilation of vascular stenosis, stent placement, catheter thrombolysis, filter implantation and vascular embolization, etc. 6.Treatment of thrombotic diseases: cerebral thrombosis, cerebral embolism, central retinal artery (static) embolism, acute pulmonary infarction, arteriovenous embolism or thrombosis of limbs, mesenteric artery embolism, etc. 7.Non-vascular intervention for luminal stenosis and obstruction, such as esophageal stent implantation for esophageal stenosis and dysphagia due to esophageal cancer, fundic cardia cancer, cardia achalasia; biliary drainage and stent placement for obstructive jaundice due to bile duct cancer, pancreatic head cancer, etc.; tracheal stenting for respiratory distress due to lung cancer and mediastinal tumor; and treatment of stenosis of duodenum, rectum, ureter, etc. 8.Aspiration and sclerotherapy of various cysts: such as liver cysts, kidney cysts, spleen cysts, ovarian cysts, etc. The treatment is complete, avoiding open surgery and not easy to recur. 9.Transcervical intrahepatic portosystemic shunt (TIPS), percutaneous puncture portal vein esophagogastric fundic varices embolization, etc. are used to treat cirrhosis portal hypertension, esophagogastric fundic varices, upper gastrointestinal hemorrhage, intractable ascites, etc. 10.Diagnosis and intervention of acute bleeding diseases (gastrointestinal bleeding, respiratory hemoptysis, organ rupture, vascular injury, pelvic organs such as uterine and bladder bleeding, etc.). Common diseases include bronchiectasis, pulmonary tuberculosis, rhinorrhea, gastroduodenal ulcer, tumor, gastrointestinal vascular malformation, traumatic liver, spleen and kidney rupture, bladder cancer, uterine hemorrhage, etc. 11.Selective tubal angiography and interventional recanalization for tubal infertility. 12.Interventional treatment of hyperfunctional diseases, including hyperthyroidism, hypersplenism, etc. 13.Cone molding (PVP) for the treatment of pain and cone instability caused by vertebral metastases, osteoporosis and vertebral hemangioma, etc. 14.Spermatic vein embolization to treat pain, infertility and sexual dysfunction due to varicocele. 15.Percutaneous lumbar disc excision and aspiration or collagenase lysis for the treatment of lumbar disc herniation. 16.Interventional treatment of aseptic necrosis of femoral head. 17.Inflammatory lesions: liver abscess, abdominal and pelvic abscesses, etc. 18.Ectopic pregnancy interventional treatment.
