Ultrasound is a non-invasive, simple, economical and efficient examination method in modern medicine. Many people may already know about ultrasound in hospitals, which has become the preferred examination method for many diseases in clinical medical work, playing an important role in the diagnosis of clinical diseases and playing an irreplaceable role in people’s health care. However, interventional ultrasound, as a component of medical ultrasound, is probably not well understood by most people. What are the aspects of interventional ultrasound? What are the applications of interventional ultrasound in clinical practice? What are the advantages of interventional ultrasound? Today, we will talk about interventional ultrasound in hospitals on this topic. 1.What is interventional ultrasound? Interventional ultrasound is an important branch of modern ultrasound medicine, which was formally established at the World Conference on Interventional Ultrasound held in Copenhagen in 1983, and it is a new technology developed on the basis of ultrasound imaging to further meet the needs of clinical diagnosis and treatment. It is under the surveillance and guidance of real-time ultrasound to complete puncture biopsy, ultrasonography and operations such as aspiration, intubation, drug injection, microwave or radiofrequency treatment of various diseases, which can avoid certain surgeries and achieve treatment effects comparable to those of surgery. 2.What does interventional ultrasound include? (a) Diagnostic ultrasound intervention: ① puncture biopsy (lesions of liver, gallbladder, pancreas, spleen, kidney, prostate, head and neck, extremities, etc.); ② fluid aspiration and testing of pleural fluid, ascites, cysts, abscesses, etc.; ③ ultrasound imaging of liver, kidney, thyroid, breast, prostate and other tumors. (2) Therapeutic ultrasound intervention: ① thoracic and abdominal fluid aspiration; ② liver, spleen, kidney, pancreas, ovary and other organs cysts and abscesses aspiration and sclerotherapy; ③ thyroid nodules aspiration therapy; ④ ultrasound guided microwave or radiofrequency thermal coagulation ablation for liver, kidney and breast tumors, etc.; 3. ①. Real-time ultrasound surveillance and guidance improve puncture accuracy and reliability. ②The treatment of cysts, substantial benign and malignant tumors under ultrasound guidance is simple in method, less damage, quick recovery, low cost and good long-term efficacy. 4.What are the advantages of interventional ultrasound compared with traditional methods? Traditional surgical pathology biopsy is difficult for patients to accept because it requires surgical procedure and is more harmful to human body. Without ultrasound surveillance, “blind puncture” can easily cause unnecessary damage to important tissues and organs, and the success rate of puncture is not high. Compared with the first two, guided puncture diagnosis and treatment has the following advantages: l Easy to operate, no pain, no radiological damage, the patient can communicate with the operator in a waking state to cooperate with the puncture.2; requires surgery, quick recovery after puncture, no scar; some patients do not need to be hospitalized, can be completed in the outpatient clinic.3 No contrast agent can be used to obtain high-quality ultrasound images, which is conducive to It is also useful for choosing the ideal puncture route and finding the safest needle path to avoid important organs and large blood vessels, thus minimizing the damage to human tissues and organs. Interventional ultrasound has been proven to be a safe, simple and effective method. 5.What are the precautions for interventional ultrasound? ①Patient precautions: Interventional ultrasound procedure: application form → ultrasound specialist clinic or interventional ultrasound group physician examination (to determine whether it is an indication for interventional ultrasound) → laboratory tests and other preoperative preparations → patient and family sign informed consent form → interventional puncture diagnosis and treatment. ② Interventional ultrasonographers should take note Puncture interventions should, in principle, be performed on an empty stomach. If suffering from severe hypertension, heart disease, diabetes, coagulation mechanism disorders, etc. should be adjusted appropriately. After the interventional treatment, patients should carry out medical advice and rest appropriately; if they feel uncomfortable such as panic and increased pain, they should seek medical attention or stay in the hospital. 6.What are the latest applications of interventional ultrasound? In recent years, the latest application of interventional ultrasound mainly focuses on the treatment of solid occupying lesions of various parenchymal organs (such as liver, kidney, thyroid, uterine adnexa) by radiofrequency or microwave, HIFI and other thermal coagulation, which is easy to apply and can even be treated without hospitalization. In addition, ultrasonography is also a new diagnostic modality that has been rapidly developed for clinical application in recent years. 7.What is microwave coagulation therapy for tumor under ultrasound guidance? Percutaneous Microwave Coagulation Therapy (PMCT) is an emerging non-surgical treatment method for tumors. It is a one-time thermal coagulation and inactivation of tumors by inserting microwave electrodes directly into the center of the tumor for heating under the guidance of ultrasound monitoring in real time. This method has the advantages of no radioactivity, real-time monitoring, simple method, small damage, fast recovery, high efficacy, low cost, no obvious contraindications, etc. It is especially suitable for patients who have lost the opportunity of surgery, and has superior performance in improving the efficacy, improving the quality of life and prolonging the survival. 8.What are the indications for microwave or radiofrequency thermal coagulation therapy? Microwave or radiofrequency thermal coagulation inactivation therapy for benign and malignant tumors of liver and kidney; ② microwave thermal coagulation inactivation therapy for breast tumors; ③ microwave thermal coagulation destruction therapy for thyroid tumors and hyperthyroidism; ④ thermal coagulation destruction therapy for splenomegaly and hypersplenism (can achieve the purpose of treating hypersplenism without cutting the spleen).
