Interventional medicine is an independent clinical discipline in hospitals. It is a separate discipline that is fully juxtaposed with general surgery, orthopedics, brain surgery, internal medicine, neurology, and gastroenterology. Because of the word “interventional”, patients generally do not know much about it, but more people need to know what kind of department it is. In fact, interventional medicine covers a wide range of diseases, although not all diseases can be treated, but there may be diseases in each department that are suitable for interventional treatment, such as gastroenterology to treat gastrointestinal bleeding, but there may be no good way for hemorrhage, but only through traditional drug treatment may lead to hemorrhage or even life-threatening. However, in interventional medicine, whether it is arterial bleeding or venous bleeding due to portal hypertension, there is a solution, and in many cases the effect is immediate, and a small procedure or treatment can achieve a very good result. There is another disease such as cerebrovascular disease, where neurology is mainly based on internal drug treatment. However, if the blood vessel is really blocked by a large thrombus, interventional medicine can take out the thrombus with immediate effect, and the patient may have a very good follow-up recovery, which is a treatment modality that cannot be compared with the traditional treatment. Although interventional medicine is not a universal department, it can often achieve very good results in a particular disease. Therefore, as many patients as possible, and even more doctors, should know about interventional medicine. When faced with a very difficult disease and limited traditional treatment options, try consulting an interventional unit.
