Since the invention of the Seldinger puncture technique, the discipline of interventional medicine has been developing at a rapid pace, and is now used not only for the treatment of vascular system diseases and bleeding, but also for the diagnosis and treatment of a variety of diseases in other systems. Interventional radiology was introduced to China in the early 1980s and has rapidly developed as an emerging edge discipline integrating medical imaging and clinical treatment. It is a “non-surgical” method to diagnose and treat various diseases by percutaneous puncture and cannulation under the guidance of imaging methods, such as drug infusion, vascular embolization or dilation and shaping. Because of its unique features in disease diagnosis and treatment (minimally invasive; reproducible; accurate positioning; high efficacy and quick results; low complication rate; easy application of multiple techniques) that traditional internal and external medicine does not have, it has rapidly established its important position in the modern medical diagnosis and treatment field. In November 1996, the State Science Committee, the Ministry of Health and the State Administration of Medicine jointly held a seminar on strategic issues of interventional medicine in China, which officially listed interventional therapy as the third major treatment discipline alongside with medical and surgical therapeutics, and called it interventional medicine. The development and popularization of interventional radiology has given patients more opportunities for recovery and has become the preferred method of elective treatment, which is much concerned and welcomed by patients. However, at present, the main patients of comprehensive interventional medicine are adults, and pediatric patients are blinded to comprehensive interventional treatment because of the low cost of treatment, the difficulty of patient management, the difficulty of operating puncture techniques, and the lack of experience of interventionalists in pediatric patient management, but children belong to the high incidence of vascular diseases, and the diagnosis and treatment of some diseases depend on DSA imaging; most pediatric liver tumors are found late and cannot be Most of the pediatric liver tumors are found late and cannot be surgically removed at the first stage; some patients, such as leukemia and short bowel syndrome, need long-term intravenous infusion. Traditional treatment methods seem to be helpless in the face of these problems, so there is a need and urgency to develop comprehensive interventional treatment in pediatrics. The scope of pediatric comprehensive interventional treatment: 1, solid tumors in various parts, especially hepatoblastoma, nephroblastoma and other soft tissue tumors can be significantly reduced or disappeared by interventional embolization chemotherapy. 2.Hemangioma and vascular malformation can be treated by image guided transcatheter or percutaneous sclerotherapy, which is effective and safe. 3, vascular diseases, DSA imaging diagnostic results are often the gold standard. 4, various organs, especially lung, liver, kidney masses of unknown nature, under the image guidance of percutaneous biopsy, can be simple, fast and safe to obtain a pathological diagnosis. 5, leukemia and other patients who need long-term chemotherapy or intravenous infusion, the implantation of the buried infusion system, eliminating various complications and psychological shadows of long-term infusion. 6.Dilatation of esophageal stricture caused by various reasons.
