Interventional medicine is a minimally invasive technique that applies modern high-tech means to diagnose and treat diseases. Under the guidance of medical imaging equipment, such as CT, MRI, DSA, ultrasound, etc., special puncture needles, catheters, guidewires and other instruments are introduced into the human body for purposeful local diagnosis and treatment of lesions in the body. Interventional therapy has become the third major clinical treatment alongside with medical and surgical treatment. It is divided into vascular interventions and non-vascular interventions according to treatment areas. Vascular interventions include vascular embolization, drug perfusion, angioplasty, etc.; non-vascular interventions include puncture, drainage, biopsy, ablation, etc. Interventional medicine is a beautiful flower in the garden of modern medicine. The magic of interventional medicine is that it has a large scope of treatment and small trauma, and it can explore the human body and do almost everything. It is less traumatic to the body, but can play a very reliable and significant therapeutic effect! Its most prominent advantages are simplicity, safety, no incision, small trauma, fast recovery, good results and few side effects.
