If a pregnant woman with fibroids is in a positive position and labor is progressing well, and the fibroids do not interfere with the birth canal, labor progress can be closely monitored and vaginal delivery can be performed. If the fetal position is abnormal, or if labor is stalled during the trial of labor, and the fibroids are blocking the soft birth canal and interfering with the descent of the fetal head, a cesarean section is required to terminate the pregnancy. In pregnant women with a history of myomectomy, vaginal delivery is possible if the fibroids are small or subplasmic; if the fibroids being removed are large and penetrate the endometrium or are close to the uterine cavity, especially in the posterior wall of the uterus, it is recommended to plan a cesarean delivery around 37-38 weeks of gestation to reduce the risk of uterine rupture. Therefore, a record of previous myomectomy is very important for the obstetrician to assess the risk. Ding Xilai, Department of Gynecology, Beijing Mizhong Yihe Women’s and Children’s Hospital
