Interventional radiology is a major component of the emerging discipline of interventional radiology, which has evolved in recent years. Simply put, interventional therapy is a kind of minimally invasive treatment using modern high-tech means. It is different from both “medicine and injection” in internal medicine and “open surgery” in surgery, but it is an extracorporeal operation under the guidance of imaging equipment (including DSA, CT, ultrasound, etc.) and special equipment (such as puncture needle, catheter guide wire, probe, etc.). It is a treatment method that can be used to achieve the purpose of treatment. It has the advantages of “no incision, little damage, fast recovery and good effect”. It is particularly suitable for the treatment of diseases for which medical treatment is ineffective and surgical procedures are not feasible, appropriate or desirable. What are the main diseases that can be treated by interventional therapy? Interventional therapy has been applied to many diseases in various parts of the body. Our department can perform most of the following interventional procedures, mainly including: 1, tumor diseases: malignant tumors such as head and neck cancer, lung cancer, liver cancer and liver metastases, gastrointestinal cancer, pancreatic cancer, kidney cancer, bladder cancer, malignant bone tumors; benign tumors such as nasopharyngeal fibrovascular tumors, liver cavernous hemangioma, etc. 2, vascular lesions: arterial stenosis lesions, Boo-ga syndrome, varicose veins of the spermatic cord or ovaries, limb and visceral aneurysms and arteriovenous malformations, etc. 3, ischemic diseases: ischemic necrosis of the femoral head, arterial or venous thrombosis, limb ischemia due to diabetes mellitus. 4.Hemorrhagic diseases: intractable rhinorrhea, pulmonary hemoptysis, gastrointestinal hemorrhage, postpartum hemorrhage, hemorrhage caused by pelvic fracture, etc. 5, non-vascular lumen obstruction: benign and malignant gastrointestinal strictures (including esophagus, cardia, pylorus, colon and trachea); obstructive jaundice (bile duct cancer, pancreatic head cancer, benign biliary tract disease); overflow of tears due to nasolacrimal duct obstruction, etc. 6.Gynecological lesions: uterine fibroids, ovarian cysts, tubal infertility, cervical cancer, uterine cancer, ovarian cancer, malignant hyperemesis gravidarum, etc. 7.Osteoarthrosis diseases: lumbar disc herniation, vertebral compression fracture due to osteoporosis, vertebral hemangioma, bone malignant tumor, etc.; 8.Other important interventional procedures: argon helium knife targeted tumor treatment, deep soft tissue metal foreign body removal, tumor puncture biopsy, hypersplenism inactivation, pulmonary herpes puncture curettage, etc. Interventional treatment of benign and malignant tumors This technique is a method of injecting drugs directly into the tumor local area and/or embolizing the tumor blood supply artery via catheter. It is suitable for intermediate and advanced malignant tumors that cannot be surgically removed. For hepatic hemangioma, this technique has gradually replaced the traditional surgical resection surgery. At present, our department has treated more than 10,000 cases of various malignant tumors, among which, the longest survival period after interventional treatment of primary liver cancer has reached more than 10 years. Interventional treatment of ischemic necrosis of the femoral head The principle of this technology is to adopt the intravascular interventional thrombolytic method to introduce the thrombolytic agent and vasodilator directly into the donor artery of the femoral head to dilate the local blood vessels, improve blood circulation and dissolve the embolus through the action of local high concentration of drugs to restore the normal blood supply to the femoral head, delay necrosis, and promote the resorption of dead bone and the formation of new bone. At present, our department has treated more than 800 cases of this type of patients, with an overall efficiency of more than 90%. Interventional treatment of vascular diseases Through a variety of advanced vascular interventional techniques, treatment of various types of vascular stenosis or aneurysm and arteriovenous fistula is carried out. For example, balloon catheter dilation and endovascular stent placement can be performed for vascular stenosis; arteriovenous fistula or arteriovenous malformation can be embolized. Interventional treatment of non-vascular obstruction/stenosis This technique uses advanced interventional techniques such as percutaneous transhepatic or transoral balloon dilation and/or endoprosthesis and endotracheal tube placement to treat non-vascular obstruction such as benign and malignant intra- and extra-hepatic biliary obstruction, benign and malignant esophageal and tracheal stenosis, esophageal fistula, and other non-vascular obstruction. It can achieve the purpose of restoring normal lumen patency and eliminating symptoms. Interventional treatment of uterine fibroids and tubal infertility The interventional treatment of uterine fibroids is performed by inserting a catheter into the uterine arteries bilaterally and then injecting embolization or sclerosing agent. It has the advantages of small trauma, quick recovery, cost saving, good effect, and can preserve the uterus and does not affect fertility. The indications for interventional treatment of uterine fibroids include: 1. symptomatic fibroids between the ages of 20 and 50; 2. those for whom conservative treatment (including drug treatment and myomectomy) is ineffective or recurrent; 3. those who are not suitable for blood transfusion and surgery; those who refuse surgery and require preservation of the uterus and fertility. Vertebroplasty Percutaneous vertebroplasty is a new technique and method to treat destructive lesions of the vertebral body to improve the stability of the spine, relieve or eliminate pain, and prevent the occurrence or development of vertebral collapse. Various patients with vertebral compression fractures due to osteoporosis and other spinal pain and spinal instability caused by primary or metastatic vertebral tumors are also indications for this procedure. Ar-He knife targeted treatment of malignant tumors and other diseases The Ar-He knife treatment system is suitable for the treatment of the following diseases: primary and metastatic liver cancer, lung cancer, prostate cancer, pancreatic cancer, breast cancer, glioma, abdominal wall tumors, etc. Advantages of argon helium knife for cancer treatment: high success rate, less damage, complete treatment, light side effects and fast recovery. The latest generation of CryocareTM minimally invasive surgery system from Endocare, the Ar-He knife, introduced by our department, was approved by the U.S. FDA for clinical use in 1998. It is a perfect combination of cryogenic cryotherapy with modern imaging technology, electronic computer technology, space technology and targeted therapy technology. It has achieved ideal therapeutic effects in the local ablation treatment of solid tumors such as lung cancer, liver cancer, kidney cancer, pancreatic cancer, prostate cancer and brain tumors. Argon Helium Knife targeted tumor treatment mechanism 1.Entering the tumor area directly and selectively, completely destroying the tumor cells through cold and heat reversal at ultra-low temperature (-140~-190℃). 2.Embolize the microtubules around the tumor, so that the potential malignant lesions around the tumor die due to ischemia and hypoxia, thus increasing the possibility of tumor eradication. 3.Enhance the sensitivity of tumor to radiotherapy and chemotherapy. For tumor cells that are insensitive to radiotherapy and chemotherapy, their sensitivity can be restored after argon helium knife cryotherapy. 4.Regulate tumor antigen, reverse tumor drug resistance and immune evasion, and significantly improve the tumor immune effect of the body. 5.The blood pool effect makes the “resection” of tumors near large blood vessels (such as the lung portal, liver portal and other large blood vessels) a reality. Advantages of argon helium knife targeted therapy 1. Significant efficacy, high success rate, and few complications. 2.Little damage, little pain, high safety, fast recovery after surgery, some patients can get up and walk in bed immediately after surgery. 3. Short operation time, suitable for patients with all stages of solid tumors, especially for patients who are inoperable or failed in other treatments. 4.Low overall cost, short hospitalization time and fast recovery. 5.Ar-He knife can be used in combination with radiotherapy, chemotherapy or surgery. Indications for argon helium knife targeted therapy In a broad sense, argon helium knife can be applied to all solid benign and malignant tumors that can be punctured, and the size is not limited, so the scope of application is relatively wide. For example: 1. respiratory system: lung cancer, benign lung tumors: 2. digestive system: liver cancer, liver metastases, hepatic hemangioma, pancreatic cancer; 3. skin lesions: skin cancer, melanoma; 4. urinary system: prostate cancer, kidney cancer, adrenal tumors, prostate hyperplasia; 5. reproductive system: perineal tumors, uterine cancer, ovarian cancer, penile cancer; 6. nervous system: temporal and parietal lobe within 4 cm Glioma, meningioma; 7. Other: breast cancer, breast fibroadenoma, oral cancer, etc. Ozone therapy is a kind of “green therapy” in the field of chronic diseases of bone and joint, which has been widely popularized in Europe, America and other developed countries in recent years. It is a novel treatment option for chronic refractory bone and joint diseases based on the strong oxidative properties of ozone gas (O3-O2) and its significant anti-inflammatory and analgesic biological effects, and the selection of the appropriate gas concentration and dose according to the characteristics of the patient’s condition to implement precise “target treatment”. Minimally invasive ozone interventional therapy has been gaining popularity among physicians and patients around the world because of its low cost and lack of significant toxic side effects. The Medical Imaging Interventional Center has recently introduced the most advanced HermannTM Ozone Therapy System from Germany, which is precisely controlled by a computer program to produce the precise concentration of gas required for treatment, with rapid infusion, and equipped with air pressure and concentration safety monitoring devices to make the entire treatment complete in one go. At present, it adopts external inflatable therapy, intramuscular injection, subcutaneous injection, painful area injection and other methods to treat a variety of bone and joint diseases such as cervical and lumbar disc herniation, frozen shoulder, “tennis elbow”, knee periarthritis, joint and muscle injury pain, etc. with excellent efficacy. The treatment process is short and the cost is low. The advantages of ozone injection treatment: 1. high safety factor, the use of fine needle puncture, almost no damage to normal tissue; 2. wide indications, can avoid the pain of open surgery; 3. accurate positioning, under the guidance of X fluoroscopy or CT puncture treatment target, to ensure that the target; 4. fast onset of action, the curative effect is stable. Generally, one to three times of treatment can achieve pain relief, with little rebound; 5, very few complications, can also treat surface infectious diseases.
