Interventional therapy is an emerging discipline – interventional radiology. Interventional therapy is a marginal and cross-disciplinary discipline combining medical imaging and clinical treatment developed in the 1970s. Due to the rapid advancement of medical imaging equipment and technology, it has also led to the rapid popularization of this discipline all over the world. With the development of the past 30 years, it has now become the third major diagnostic and treatment technology along with internal medicine and surgery. Previously, internal medicine and surgery are considered incurable or intractable diseases interventional radiology have opened up new and effective treatment methods. Because it is not like the traditional internal medicine, there are different from the surgical “bold”, between the two, so the image is called interventional radiology. The concept of the latest standard of interventional radiology is: in the medical imaging equipment (X-ray machine, B ultrasound, CT, and even MRI) under the supervision of percutaneous or trans-luminal insertion of puncture needles or the introduction of catheters, guide wires to do suction, injection, drainage, fistula, or the cavity, blood vessels to do molding, perfusion, embolization of minimally invasive diagnostic and therapeutic techniques. From the concept we can analyze: 1, interventional radiology is first of all a medical imaging (diagnostic) technology. 2, interventional radiology is a minimally invasive technology. 3, interventional radiology is a clinical treatment. 4, interventional radiology is a marginal, cross-disciplinary. Above is Handan 285 Hospital Interventional Center for us to introduce what is the interventional therapy, the next continue to say what benefits of interventional therapy in the end. Interventional therapy is characterized by small trauma, simple, safe, effective, fewer complications and significantly shorter hospitalization time. For diseases that require medical treatment, the advantages of interventional therapy compared to medical treatment are: the drug can act directly on the lesion site, not only can greatly increase the concentration of drugs in the lesion site, but also greatly reduce the dosage of drugs and reduce drug side effects. For diseases that require surgical treatment, the advantages of interventional therapy over surgical treatment are: 1, it does not require incision to expose the lesion, usually only a few millimeters of skin incision, the treatment can be completed, epidermal damage is small, beautiful appearance. 2, most of the patients only need local anesthesia, and the patient can be treated with local anesthesia, and then the patient can be treated. 2.Most patients only need local anesthesia rather than general anesthesia, thus reducing the risk of anesthesia. 3.Small damage, fast recovery, satisfactory results, and small impact on normal organs of the body. 4.For malignant tumors which are difficult to be treated nowadays, interventional therapy can try to confine the drugs to the lesion area and reduce the side effects on the body and other organs. Some tumors are equivalent to surgical resection after interventional therapy.
