With the development of embolization therapy for adenomyosis, it has become a powerful treatment for adenomyosis. Currently, 80% of patients can be spared the pain of hysterectomy, and the efficacy of the treatment for excessive menstrual flow reaches 90%. This treatment has given hope to a large number of patients! However, there are huge efficacy gaps in the implementation of the technique! Poor quality control at every stage of the technique can lead to treatment failure! Specifically, the technology should pay attention to the following aspects: 1, the selection of patients, the same is adenomyosis different patients are not the same situation, the need to carefully distinguish the characteristics of each case, from the condition to the examination should be carefully distinguish to find out the appropriate case, rely on a single ultrasound results can no longer satisfy the requirements of the selection of patients; 2, uterine artery cannulation technology – the most basic Interventional techniques, the requirements of fast, accurate, light, to reduce the damage to the uterine artery, in addition, pay attention to the catheter on the blood flow, which is the most easily overlooked details affecting the efficacy of the treatment; 3, the choice of embolization materials, the current embolization of a wide range of materials, materials, specifications of a large number of, however, our experience illustrates the embolization of the choice of materials is very important, different embolization of materials may lead to varying efficacy, and the same choice of the correct specifications of the embolization material is also a major factor in the efficacy of the treatment. The choice of the correct specification of embolization material is also a guarantee of efficacy; 4. Embolization – the top priority of the whole technique! Embolization process, the size of the embolization material, embolization of the concentration of the embolization material, embolization material before and after the order of the embolization, the degree of embolization, these are the key in the key! It is a reflection of experience! 5. In addition, the dietary requirements for the patient after discharge from the hospital are likewise key to ensuring efficacy! We started this technique in 1998, which is one of the earlier units in China to carry out this technique, and at the same time, it is also one of the units with the largest number of single person times to do this operation, therefore, our experience is also rich, the above points are our experience, and we hope that it can bring good news to the majority of patients with adenomyosis!
