Interventional therapy is a kind of minimally invasive treatment using modern high-tech means, that is, under the fluoroscopic guidance of digital subtractive imaging (DSA) and catheter technology, the therapeutic substances are sent into the localized lesions to treat the lesions in the body. Therefore, interventional therapy is characterized by minimally invasive treatment, strong reproducibility, accurate positioning, high efficacy, quick results and low complications. Interventional radiology is an emerging discipline integrating medical imaging and clinical therapeutics, which involves the diagnosis and treatment of many systemic diseases such as digestive, respiratory, cardiovascular, neurological, urological, and gynecological diseases. At present, interventional therapy has become one of the main means of clinical treatment in modern medicine, and it is the third major treatment method developed after internal and surgical treatment, solving the problems that cannot be solved by internal and surgical treatment. The Interventional Therapy Department of our hospital has a large digital angiography machine of GE Company of the United States, a modernized interventional operating room, equipped with advanced rescue equipment such as monitor, defibrillator and suction device, etc. The department also cooperates with many hospitals in China and the province. And with the domestic and provincial hospitals interventional experts often technical communication, a number of experts in person to guide, get a strong technical support. Now, we mainly carry out the treatment of the following diseases: 1, non-vascular diseases, such as congenital tracheobronchial and esophageal stenosis stenting treatment; tracheobronchial and esophageal stenosis stenting treatment caused by tumor trauma and postoperative; esophageal-tracheal fistula laminar stenting; benign and malignant tumors caused by obstructive jaundice (bile duct obstruction) of internal and external drainage or internal stenting; cardia dystrophy balloon dilatation Treatment of jaundice. Vascular diseases, such as thrombolysis or endovascular stenting for arterial stenosis and obstruction caused by various reasons; endovascular stenting for aortitis, renal artery stenosis, traumatic stenosis, Buerger’s syndrome, arterial entrapment; endovascular stenting or embolization for aneurysm; embolization for arteriovenous malformation. 3, bleeding disorders, traumatic bleeding, such as: liver and spleen rupture, kidney injury, pelvic hemorrhage, gastrointestinal bleeding drug perfusion or embolization treatment; hemoptysis of the bronchial artery embolization treatment; in order to reduce intraoperative bleeding in the operation of preoperative resection of lesions in the blood supplying artery embolization treatment. 4.Tumor diseases, such as: liver cancer, hepatic hemangioma, renal cancer, pancreatic cancer, pelvic tumors, bone tumors, drug infusion and embolization treatment. 5.Reproductive system diseases, such as: female infertility due to tubal stenosis, microcatheter and microguidewire recanalization treatment; uterine fibroid, uterine adenomyosis embolization treatment; ectopic pregnancy drug perfusion and embolization treatment. 6, lesion percutaneous puncture biopsy, such as lung occupation of puncture biopsy. 7.Interventional organ removal, such as the embolization treatment of hypersplenism. 8, Other, such as prevention of pulmonary artery embolism inferior vena cava filter placement.
