General Information About Interventional Therapy II
There are many interventional techniques, which can be firstly divided into vascular interventional techniques and non-vascular interventional techniques. Coronary angiography, thrombolysis and stent placement for the treatment of angina pectoris and acute myocardial infarction, which are familiar to everyone, are typical vascular interventional techniques. The percutaneous biopsy, radiofrequency ablation, argon-helium knife, and radioactive seed implantation of tumors such as liver cancer and lung cancer belong to non-vascular interventional techniques. According to the system to which the disease is treated, it can be further divided into neuro intervention, cardiovascular intervention, tumor intervention, obstetrics and gynecology intervention, and musculoskeletal intervention.
There are many types of diseases that can be treated with interventional therapy, including almost all major diseases of various systems and organs in the body. Of course, its advantages mainly lie in the minimally invasive treatment of vascular and solid tumors.
Vascular diseases: including percutaneous transluminal angioplasty and vascular stent placement for the treatment of vascular stenosis and occlusion, thrombolytic therapy for the treatment of arterial and venous thrombosis, control of bleeding (acute and chronic trauma, postpartum, inflammation, varicose veins, etc.), Vascular malformations, embolization of arteriovenous fistulas and hemangiomas, inferior vena cava filter for prevention of pulmonary embolism, transjugular intrahepatic portosystemic shunt (TIPSS) technique for the treatment of portal hypertension in cirrhosis, various angiographic diagnosis, venous Blood tests, etc.
Tumor diseases: including tumor feeding arterial embolization and drug perfusion, preoperative tumor blood vessel embolization, tumor percutaneous biopsy, radiofrequency ablation, cryoablation (argon-helium knife), radioactive seed implantation, etc.
Non-vascular interventional techniques include various percutaneous needle biopsy, various non-vascular cavity angioplasty (including the dilatation and stenting of stenosis of the urinary tract, digestive tract, respiratory tract, biliary tract, etc.), local inactivation of solid tumors (via Skin puncture, intratumoral drug injection, radiofrequency ablation), cyst abscess drainage, ostomy (stomach, bladder, etc.), minimally invasive lithotripsy for bile duct and kidney stones, vertebroplasty for bone metastases or vertebral compression fractures , plexus block for the treatment of chronic pain.
