What is interventional therapy? Interventional therapy is an emerging discipline that has been developed in recent years. Simply put, interventional therapy is a minimally invasive treatment using modern high-tech tools. In terms of methods and means, it is different from both “medication and injection” in internal medicine and “open surgery” in surgery, but it is a treatment of lesions in the body through the extracorporeal operation of special catheters placed in the body under the guidance of imaging equipment. Therefore, it has the characteristics of “no incision, little damage, fast recovery and good effect”. It is especially suitable for those patients who cannot be treated by medical drugs (such as liver cancer, lung cancer, etc.) and cannot, should not or do not want to receive surgical treatment. At present, interventional therapy has become one of the main means of clinical treatment in modern hospitals. Features of interventional therapy Minimally invasive, high-tech and highly efficient are its most important features. Minimally invasive: The interventional incision is usually only about 3 mm, and no sutures are needed. Patients can walk on the ground the day after the procedure. High-tech: Interventional devices and methods all adopt the most advanced technology in the field of medical development in the 21st century, representing the direction of contemporary medical development. High efficiency: Interventional treatment is especially suitable for patients who are unable to be treated with medical drugs and are unable, inappropriate or unwilling to undergo surgical treatment. What diseases can be treated with interventions? Since the beginning of clinical use of interventional techniques in the 1970s, interventional treatment has involved many diseases in various parts of the body due to the improvement of interventional devices and the development of interventional techniques. These mainly include: 1, tumor diseases: malignant tumors such as liver cancer, lung cancer, kidney cancer, stomach cancer, colon cancer, pelvis, etc., and benign tumors such as hepatic hemangioma, uterine fibroids, uterine adenomyosis, etc. 2.Vascular diseases: arterial stenosis/occlusion, aneurysm, arteriovenous fistula, Buga’s syndrome, deep vein thrombosis, pulmonary embolism, upper and lower vena cava obstruction syndrome, vascular malformation, etc. 3.Non-vascular diseases: benign and malignant esophageal and tracheal stenosis and esophageal fistula, benign and malignant biliary obstruction (obstructive jaundice) and intestinal stenosis/obstruction, etc.; liver and kidney cyst, liver abscess, aseptic necrosis of femoral head, etc. 4, bleeding disorders: arterial or venous gastrointestinal bleeding (vomiting blood, blood in stool), hemoptysis caused by lung diseases; bleeding of liver, spleen, kidneys and other organs caused by various reasons and intractable nasal bleeding, etc.
