(267 ) 268 SPECIAL DIAGNOSIS Etiology. Atresia of the vagina may be congenital or may be difficult to determine whether the malformation developedin intrauterine or in extrauterine life. In very young infants avaginitis may form adhesions of the vaginal surfaces without giv-ing rise to symptoms. Whether a fetal vaginitis can account forcongenital atresia of the vagina has not been demonstrated. The usual cause of stenosis and atresia of the vagina occurringduring the period of sexual maturity is trauma incident to labor. Fig. 100 Fimbriated extremityof tube. Broad ligament,upper part. \Artery vein. Vagina, anterior wall. The uterus and its appendages. Posterior view. The parts have been somewhat dis-placed from their proper position in the preparation of the specimen; thus the right ovary-has been raised above the Fallopian tube and the fimbriated extremities of the tubes havebeen turned upward and outward. (From a preparation in the Museum of the Royal Collegeof Surgeons of England.) In the postclimacteric stage an adhesive vaginitis may narrowor obliterate the vagina. Gonorrhoea is the usual underlyingcause of senile vaginitis. In congenital atresia the obstruction ismost often at the junction of the middle and upper third of thevagina, which is the lower limit of the Miillerian ducts. In theacquired form the obstruction is usually similarly situated. The obstruction may be merely a half-moon or annular ring, apartial or complete septum with perforations, or a membrane vary-ing in thickness even to filling the vagina complet
