Flashcards in Congenital anomalies of the cervix Deck (14):
paramesonephric (mullerian) ducts
sixth week of development
2 mullerian ducts give rise to
uterine corpus, cervix, and upper vagina
Müllerian duct anomalies result from (4 etiologies)
Most common type of mullerian fusion defect
lateral fusion defect--resulting organs may be symmetrical, asymmetrical; obstructed or unobstructed.
:Uterine septum; partial or complete
fusion of mullerian ducts with the urogenital sinus
What type of failure is characterized by a double cervix
longitudinal vaginal septum--lack of fusion
Single hemicervix or septate cervix composed of single muscular septum that can be an extension of a lower uterine segment or vaginal septum
20-30% of women with mullerian duct abnormalities also have
urinary tract abnormalities.--image urinary tract if gyn abnormalities found.
Sex characteristics of women with mullerian duct abnormalities
Normal ovaries and normal secondary sex characteristics.
Rare--absent uterine cervix with a normal uterine corpus and vagina
:failure of mullerian duct canalization or abnormal epithelial proliferation after canalization
absence of the cervix combined with absence of the uterine corpus and upper vagina
müllerian agenesis or Mayer-Rokitansky-Kuster-Hauser syndrome
Cervical agenesis with normal functioning uterine corpus must be differentiated from
cervical agenesis leads to retrograde flow--endometriosis
Nonsurgical and surgical treatments to lengthen or create a vagina
