Vaginal atresia

Introduction Complete occlusion of the vagina, mostly due to congenital malformation, the patient's uterus is often underdeveloped, so even if surgery is used to correct the vagina, the chance of conception is minimal. Incomplete vaginal atresia is often a scar contracture stenosis caused by birth injury, corrosive drugs, surgery or infection. It has only small holes in the center, and the lower position of the lock can affect sexual life. In pregnancy, scars can be softened and softened as the pregnancy progresses. For example, only mild annular or semi-circular stenosis, the first exposed part of the scar has a continuous expansion effect on the annular scar, and often overcomes such obstacles and completes the delivery. If the position of the lock is low, one-sided or bilateral preventive perineal side-cutting may be performed according to the situation to prevent severe perineal laceration. If the scar is wide and the part is high, it is not suitable for vaginal delivery.
