Interventional therapy is a minimally invasive treatment using high-tech means. It is different from “medicine and injection” in internal medicine and “open surgery” in surgery, but under the guidance of medical imaging equipment such as DSA, ultrasound, CT and MRI, special puncture needles, catheters, guidewires, stents and embolic agents are used instead of traditional scalpels to diagnose and treat diseases. Instead of traditional scalpel, special puncture needles, catheters, guidewires, stents and embolic agents are used to diagnose and treat diseases. It has the characteristics of “accurate positioning, no incision, little damage, good efficacy and quick recovery”. At present, interventional therapy has become one of the main means of clinical treatment in modern hospitals and is becoming more and more popular among patients. What are the main diseases that can be treated by interventional therapy? 1.Liver cancer and lung cancer: interventional therapy is the first choice for the treatment of middle and late stage liver cancer, and radiofrequency ablation treatment for some small liver cancers can achieve the effect of surgical resection; for middle and late stage lung cancer, interventional therapy + radioactive particle implantation can significantly improve the survival quality of patients. 2.Uterine fibroids: In Europe, America and China, interventional therapy has become one of the main treatment methods for uterine fibroids. It can save 90% of patients with fibroids that need to be removed surgically from the pain of hysterectomy. 3.Cerebrovascular lesion treatment: diagnosis of cerebrovascular disease atherosclerosis and cerebrovascular stenosis, embolization of cerebral arteriovenous malformation, spring coil filling of cerebral aneurysm, ultra-early arterial selective thrombolysis of thrombotic cerebrovascular disease, thrombolysis of intracranial venous thrombosis, angioplasty and stent implantation, repair of cerebral arterial endothelial entrapment. 4.Vascular lesions: arterial (venous) stenosis and occlusion caused by various reasons, aneurysm, arteriovenous malformation, venous thrombosis, hemangioma (especially hepatic hemangioma, limb hemangioma), feasible vascular balloon formation, thrombolysis, vascular stenting, vascular embolization treatment. 5, bleeding diseases: gastrointestinal bleeding (vomiting blood, blood in stool), hemoptysis caused by lung diseases, pelvic hemorrhage, ruptured liver, spleen, kidney bleeding, interventional arterial embolization treatment of bleeding diseases can achieve “immediate” effect of hemostasis. 6.Malignant tumor: Interventional treatment including interventional embolization and particle implantation radiotherapy is an important method of comprehensive tumor treatment, which can treat head and neck tumors (nasopharyngeal cancer, tongue cancer, etc.), abdominal tumors (stomach cancer, bile duct cancer, pancreatic cancer, kidney, etc.), pelvic tumors (bladder cancer, prostate cancer, cervical cancer, ovarian cancer, etc.). 7, luminal stenosis lesions: benign and malignant esophageal stenosis, esophageal fistula, benign and malignant biliary obstruction (obstructive jaundice), urinary tract obstruction, post-surgical anastomotic stenosis, nasolacrimal duct obstruction, etc. 8.Diseases of portal vein system: cirrhotic portal hypertension, esophagogastric fundic varices. 9.Partial splenic artery embolization: treatment of splenomegaly, hypersplenism, thalassemia, thrombocytopenic purpura. 10.Fallopian tube angiography and recanalization for female infertility, sclerosing embolism of varicocele. 11.percutaneous puncture biopsy of chest and abdominal masses. Various cysts and abscesses treated by percutaneous aspiration and drainage.
