Uterine fibroids during pregnancy are prone to have various kinds of degeneration，but red degeneration is the most common and is one of the obstetric emergencies，which in severe cases might lead to adverse pregnancy outcomes. The degeneration of uterine fibroids during pregnancy should be adequately evaluated in clinical work，and symptomatic supportive treatment should be actively performed in order to reduce the risks associated with pregnancy.
