Complete vaginal atresia is mostly due to congenital developmental abnormalities, and the patient’s uterus is often underdeveloped, so even if surgery is used to correct the vagina, the chances of conception are extremely low. Incomplete atresia of the vagina is often formed by birth injury, corrosive drugs, surgery or infection and scar contracture narrowing, the center of which only leaves a small hole, the atresia position of the low can affect sexual life. During pregnancy, the scar can be softened by congestion with the progress of pregnancy. If there is only a mild circumferential or semi-circumferential stenosis, the preluxation part of the ring after labor has a continuous dilatation effect on the circumferential scar, which can often overcome this obstacle and complete the delivery. If the atresia is low, unilateral or bilateral prophylactic episiotomies may be performed as appropriate to prevent severe perineal lacerations. If the scar is extensive and high, vaginal delivery is contraindicated and cesarean section is preferred. Symptoms are similar to those of hymenal atresia, and there is no vaginal opening on examination, but the mucosal surface at the atresia is normal in color and does not bulge outward, and anal examination reveals a vaginal blood mass projecting toward the rectum, which is higher than that of hymenal atresia. Vaginal examination is diagnostic. Congenital anomalies, birth injury, corrosive drugs, surgery or infection and the formation of scar contracture stenosis.
