Interventional surgeries require the wearing of a lead suit for the procedure, as angiography and other x-ray emitting medical devices are used in interventional surgeries, and the doctor needs to wear a lead suit for self-protection. Lead coats can effectively minimize radiation damage, and the use of angiographic agents during interventional procedures makes the blood vessels in the body visible, which facilitates the operation and diagnosis of the doctor. Currently, interventional procedures are divided into several categories, including peripheral vascular intervention, neurological intervention, tumor intervention and so on. Interventional therapy is based on imaging equipment, it is inevitable to avoid radiation damage, wearing a lead suit can reduce the amount of radiation absorbed. Radiation has a great impact on the human body, and the amount of radiation received in interventional procedures is unavoidable for doctors, but we should pay attention to protection in our daily lives and stay away from sources of radiation.
