Interventional therapy refers to the method of inserting specialized medical devices into specific parts of the human body to examine and treat diseases with the assistance of radiological equipment. It is one of the fastest growing and most widely used emerging medical disciplines. So what can it treat?
Liver diseases: including liver cancer liver, hemangioma, liver puncture biopsy, cirrhosis, portal hypertension. Splenic duct and pancreatic lobe diseases: gallbladder cancer, cholecystitis, pancreatic cancer; gastrointestinal tract and spleen: gastric cancer, gastrointestinal bleeding, hyperfunction of the liver. Diseases of urinary and reproductive system: kidney tumor, bladder tumor, varicocele, prostatic hyperplasia, tubal infertility, gynecological malignant tumor. Adrenal diseases: primary and metastatic adrenal tumors. Abdominal vascular lesions: multiple aortitis, abdominal aortic adenoma, renal vascular hypertension, pelvic hemorrhage and so on. It can be seen that the diseases suitable for interventional therapy are mainly cancer and vascular diseases.
So how does interventional therapy treat these diseases? It is through some special tubes - medical catheters - that the items and medicines needed for treatment are delivered to specific areas, so that the diseased areas can be restored to normal or be in a therapeutic state. For example, interventional therapy for liver cancer is performed by inserting a puncture needle into the femoral artery from the patient's groin (root of the thigh) and then placing a catheter so that it travels along the femoral artery through the abdominal aorta to the hepatic artery, where it releases some contrast agent (a drop of medicine that can be seen under the X-ray). With the help of X-ray, the specific location of the lesion can be found by observing the flow of the contrast agent, and then the catheter can be pushed along the artery into the artery of the corresponding area, releasing some drops (bolus) that temporarily block the flow of blood to temporarily interrupt the blood supply to the area of the lesion, and followed by the injection of some chemotherapeutic drugs, so that they can stay for a long period of time in the area of the lesion at a concentration that is hundreds of times higher than the systemic use of the drug, and the effect of the treatment is greatly improved

Simple understanding is:
1. What is intervention?
You may know about medication in internal medicine, surgery in surgery, and radiation therapy in radiotherapy ...... but you may not have heard of interventional therapy. What is interventional therapy? Interventional therapy is a minimally invasive treatment using modern high-tech means - that is, under the guidance of medical imaging equipment, special catheters, guide wires and other precision instruments, introduced into the human body, the body's pathology for diagnosis and local treatment. Interventional therapy applies digital technology to expand the doctor's field of vision, with the help of catheters and guide wires to extend the doctor's hands, and its incision (puncture point), which is only the size of a grain of rice, without cutting through the body's tissues, can treat many diseases that could not be treated in the past, and which must be operated on or have poor efficacy of internal medicine treatments, such as tumors, hemangiomas, and various kinds of bleeding. Interventional therapy is characterized by no incision, little trauma, fast recovery and good results.
