The advantage of uterine artery ligation is that it can stop the bleeding of the uterus and preserve the uterus. The disadvantage is that it can harm the uterus and ovaries, which will lead to reduced menstrual flow, prolonged cycle, premature ovarian failure and early menopause. 1. Advantages: Caesarean section and removal of fibroids can lead to heavy bleeding from the uterus. In order to protect the uterus as much as possible and minimize the damage to the woman, ligation of the uterine arteries can be used to stop the bleeding. 2. Disadvantages: Damage to the uterus will affect the blood circulation of the uterus and the ovaries, which will result in insufficient blood supply and lead to complications, such as decreased menstrual flow, prolonged cycle, premature ovarian failure and early menopause. Although uterine artery ligation can help to stop the bleeding of the uterus, it can cause certain damage to the body, so it is important to follow the doctor’s advice and choose the appropriate treatment in case of emergency.
