Pregnancy in a non-communicating, rudimentary uterine horn. A reason for failed therapeutic second trimester abortion. 1979

R Kirschner, and T Löfstrand, and J Mark

Anatomical aberrations in the female genital tract are due to maldevelopment of the Müllerian duct system. Various degrees of malformations are described (9). Some of these malformations are discovered during the investigation of amenorrhea, persistent dysmenorrhea or infertility, while others are discovered in connection with obstetrical problems. The incidence of uterine malformations is quoted as 1:1 500-2 000 (8, 11), the incidence of uterus unicollis bicornis being as rare as 1:100 000 (3). There is no unified nomenclature for the rare types of genital malformations. Semmens describes a group consisting of functional uteri of single Müllerian origin, labelled uterus unicollis bicornis with one rudimentary horn (8). Most rudimentary horns are hollow and allow the expansion of an up to 20 weeks pregnancy (3). Few cases of pregnancy in a rudimentary horn have been seen, causing complications during pregnancy and delivery, and when performing therapeutic abortions (2, 3, 4, 5, 6, 12).

UI	MeSH Term	Description	Entries
D009095	Mullerian Ducts	A pair of ducts near the WOLFFIAN DUCTS in a developing embryo. In the male embryo, they degenerate with the appearance of testicular ANTI-MULLERIAN HORMONE. In the absence of anti-mullerian hormone, mullerian ducts give rise to the female reproductive tract, including the OVIDUCTS; UTERUS; CERVIX; and VAGINA.
