(1) digestive system: interventional chemotherapy and embolization of medical malignant tumors of the liver, stomach, pancreas and intestines; dilation and stenting of benign and malignant stenosis and obstruction of the esophagus and biliary tract; interventional embolization of hepatic hemangioma, hepatic cysts and hypersplenism. (2) Respiratory system: interventional chemotherapy and embolization of lung cancer; interventional embolization of hemoptysis; expansion and stenting of benign and malignant stenosis and obstruction of airway. (3) Circulatory system: dilation and stenting of arterial and venous stenosis; thrombolysis of acute and chronic peripheral arterial and venous thrombosis; embolization of peripheral aneurysm and cavernous hemangioma. (4) Neurological system: embolization of cerebrovascular disease (aneurysm, arteriovenous malformation, cavernous sinus fistula, etc.); thrombolysis of cerebral thrombosis in the acute stage. (5) Bone and soft tissue system: interventional chemotherapy and embolization for malignant tumors of bone and soft tissue; vertebroplasty (for vertebral collapse and vertebral hemangioma caused by osteoporosis and metastatic tumors); interventional treatment of intervertebral disc herniation; interventional treatment of aseptic necrosis of the femoral head. (6) Genitourinary system: interventional chemotherapy and embolization of malignant tumors of kidney, pelvis and breast; embolization of uterine fibroids in the blood vessels;, interventional treatment of renal cysts, interventional treatment of pelvic hemorrhage. Thus, with the continuous progress of clinical medicine and the development of modern science and technology, interventional therapy can undoubtedly bring a new dawn to mankind in conquering persistent diseases, and at the same time discover a broad prospect for the development of human life sciences.
