The mechanism of interventional treatment for uterine fibroids: Essentially, the de-vascularization of uterine fibroids is an important part of interventional treatment for uterine fibroids, and this selective de-vascularization is related to the characteristics of the blood supply of fibroids. The advantages of interventional embolization of uterine fibroids: 1, exact efficacy: except for individual types, it has good efficacy for all types and sizes of uterine fibroids, and the fibroids shrink significantly after embolization and remain stable, with low recurrence rate and obvious elimination of clinical symptoms for those with mainly bleeding symptoms. 2.Small trauma: Only a small incision of 2~3mm is made on the surface of femoral artery, compared with traditional open surgery and laparoscopic surgery, the trauma is small, the technical operation is simpler, and the postoperative complication rate is low. 3.Uterus function and normal fertility can be preserved. 4, high patient satisfaction: foreign scholars through the two groups of patients after treatment satisfaction survey results show that 71% to 94% of women are willing to choose this treatment mode again, only 6% of women are willing to choose other treatment methods. Since the bleeding was controlled, menstruation returned to normal, and symptoms such as anemia, pelvic pressure and discomfort improved after treatment, it made most patients’ quality of life significantly improved. 5.Short hospital stay and quick recovery, you can get out of bed 20 hours after the operation. 6.After treatment, it does not affect other treatments, in other words, even if embolization fails, patients can receive other treatments. Interventional treatment of uterine fibroids has been carried out in China for nearly ten years, with mature technology and large number of case reports showing that its efficacy is certain and has been gradually accepted by the majority of patients with uterine fibroids, and has become the preferred treatment method in developed areas of China.
