Interventional therapeutics began in foreign countries in the late 1960s and began to be applied in China in the early 1980s, but it has developed rapidly and some aspects have reached or are close to the world’s advanced level. At present, interventional therapy technology is becoming more and more perfect and has attracted widespread attention in the world medical community, setting off a wave of research and application. Because of its characteristics of minimally invasive, high efficiency and low complications, interventional therapy has become the preferred treatment option for many diseases and is widely used in various systems throughout the body. 1.
