However, many patients do not know what interventional therapy is, including some doctors who are confused about what interventional therapy can actually do. But they don’t know when to see the interventional department? Now let’s talk about what interventional therapy is. Interventional therapy is developed gradually with the development of medicine and other disciplines, such as physics, materials science, etc. It has been developed abroad for nearly a hundred years, and in China it was first carried out in large hospitals such as Shanghai and Beijing after the 1970s, and then gradually developed to the municipal level and now even to the county level. Some hospitals have set up interventional therapy departments or interventional radiology departments, set up wards and outpatient clinics, and some are attached to radiology departments to carry out interventional treatments of varying difficulty. Interventional therapy, or interventional radiology, is a discipline that uses minimally invasive techniques to diagnose or treat diseases under the surveillance of imaging equipment such as X-ray machines, CT, MRI, ultrasound machines, and so on. From the definition, we can see that interventional radiology includes two aspects; on the one hand, it can be used for diagnosis, such as using a biopsy needle to remove a small piece of tissue from a lesion for pathological examination to clarify the nature of the lesion; on the other hand, it can be used for minimally invasive treatment, which is to receive results comparable to surgical procedures with minimal trauma, or even better than surgical treatments in some cases. Interventional treatment can be divided into endovascular and non-vascular interventions depending on the method. As the name implies, endovascular interventions are treatments performed inside blood vessels, which can treat benign and malignant tumors, bleeding, vascular stenosis or occlusion, vascular malformation, hemangioma, etc. Non-vascular interventions are treatments performed in tissues or non-vascular lumen, such as stenting or balloon dilation treatment for esophageal stenosis, interventional treatment for bile duct stenosis or obstruction, intra-tumor drug injection ablation, radiofrequency ablation of tumors, microwave therapy, argon helium knife treatment, radioactive treatment, and radioactive treatment. treatment, argon helium knife treatment, radioactive particle implantation, and so on. Whether it is endovascular intervention or non-vascular intervention, the trauma is very small, the patient suffers little pain, recovers quickly, and the effect of the procedure is obvious. In some cases, such as bleeding, esophageal stenosis, vascular stenosis or occlusion, interventional treatment can achieve immediate results, and the patient can receive the treatment effect immediately. The development of interventional therapy has provided many good treatments for clinical treatment, solving many clinical problems and relieving patients of their pain, so interventional therapy should be understood and utilized to better serve patients.
